This was a great reaction thank you for doing it! I find the conversations you were having when your mind tries to wrap around the real scale of how big things are, is so interesting. Hope you enjoyed it as well!
@@AsiaandBJReact Ill never put a video down that inspires people to start talking, for that the video deserves commendation. However i would take some of it with a pinch of salt, the original video while informative, has an incredible amount of speculation in it masked as fact. In fairness i suspect its to simply help the viewer understand the concepts easier, but at the same time its very misleading and ultimately delivers misinformation which doesn't really help anyone. I'll give you a single example (of which there are many), he said "Any Civilization outside this space would be unaware of our presence". For one, he cannot possibly know that, unless he has discovered alien life it is an assumption and pure speculation. Secondly, any civilization that was technologically advanced enough would not be using radio to communicate, its too slow. When you are dealing with the LY scale and civilizations that explore and traverse these kinds of distances, Radio would be the equivalent of smoke signals using a match. Admittedly, this is speculation on my part, but you would think they would use somthing like quantum entanglement for data transmission. Entanglement would negate distance as a hurdle, regardless of the scale. Hell, we as humans havent even visited another planet yet and we know how to make entanglement work. A single assumption that any other life in the universe would follow the exact same technological path a humans is very arrogant to say the least.
Now that you've watched this one and realize the enormity up the visible universe, you should check out "Origin: probability of a single protein forming by chance" by Philip C. Religious or not it's hard to wrap your head around it. The idea of a higher intelligence or God is just inescapable.
Intuitively, we tend to think that there are as many stars out there as there are grains of sand in a fire bucket...maybe. In fact, here are more than there are grains of sand on this entire planet...by several orders of magnitude. And the nearest one is 4.2 light years away. Absolutely mind-blowing.
Asia, think about Voyager 1 this way: It was launched on Sept 5, 1977 - 45 years ago! - and has been traveling at 38,000 miles per hour! Yet it's only gone that far.
I love that guy. He got me into astrophysics, him an Brian Cox. Now I'm hooked on Neil DE Grasse Tyson. I'm too old old, hope I can inspire the kids to start early and get good grades in the Physics and Maths
@@scottdarden3091 Point is you can't describe it because anything is a possibilty, but you have little to no idea what exists, or existed in our time period.
@@scottdarden3091 Your mind cannot actually conceive infinity, just a vague concept of something that does not end. The scope of the universe is not only beyond your understanding, but far beyond anything your brain is capable of understanding.
What blows my mind is when you look up, you're looking into the past. Even if you look at the sun you're looking 8 min into the past. Some of the stars you look at you are looking millions of years into the past.
I remember when Voyager was spun to take the picture of earth, in schools and on the news worldwide everyone was asked if they were able to participate in a global event. At a set time walk outside look up smile and wave. It was 9 PM ish I recall I was allowed to stay up a little past my bedtime. Me and my brothers and sisters all walked out and did it. Later I realized how cool it was that I looked up and down the block and seen people I knew joining in, then realizing people around the world in every time zone in countries Id only read about. People I'd never know where sharing in that with us. A beautiful moment of global unity. We used to have those then. Not so much anymore with the global elite tarring it all down.
Elon Musk, along with the rest of the billionaires and international cooperation for the JWST are points that objectively tear apart your last sentence. The Artemis mission is scheduled for like right now and you've gone and screwed up what otherwise was a beautiful memory and message with utter BS. Good job. 👍
Here's the idea going in the opposite direction: Every cell in our body contains 2 meters of DNA. Our bodies are comprised of about 30 Trillion cells. The speed of light is almost exactly a billion kilometers per hour. And that means it would take light about 30 hours to travel the length of the DNA inside each of our bodies. From tiny to huge, the universe is worth paying attention to. You guys should consider doing the Veritasium video on what trees are made of. His stuff is super well explained, but fascinating. And he's solid in his facts. He gets tested by the best--he has highly educated viewers keeping tabs on him. :-)
That's true and they called him out on one of his sponsored videos where he is less than totally honest, head doing amazing work of bringing the sciences to the masses
That bit about the cumulative length of DNA in a person’s body just sent me for a trip. It always amazes me when a handful of concepts I understand rationally are reframed in a novel way, such that I can immediately sense my entire instinctual understanding of the universe reshaping itself.
I can't even see straight right now. What's crazy to think about is as big as the universe is, its equally as mind blowing if you start looking in the opposite direction into the molecules that make up everything we can observe. How small everything gets.
Yea that's crazy because we don't know what's up there, and we don't know what's down here like under the oceans. We don't know the very big, but not the very small either
@@roxee57 You might even say a million times smaller than 'the' electron, if you follow the idea that only one electron exists in multiple places. And, in fact, if you consider the positron as an electron that's going backward through time, then all positrons and electrons are the same particle swinging forward and backward through time. I personally don't think this is right, but it's fun to consider.
What they said about it taking 20 minutes at lightspeed for a message to go from Earth to Mars: The Mars rovers are the same so when they want to send a computer command to the Mars rovers it takes 20 minutes for the message to get there and 20 minutes for the response to get back to Earth. Can you imagine everytime you did something on your computer it took 40 minutes for your computer to respond to your command? It makes things complicated!
It’s actually wrong information, it does not take light 20 minutes to travel to mars, it only takes 3 minutes, I’m not sure where he got 20 minutes. Since it takes only 8 minutes for light to hit the earth from the sun and Mars is much closer.
@@YoungBlood507 The minimum amount of time is ~4 minutes, the maximum is 20 minutes depending on the position of the planets. The distance changes as the planets orbit.
Astronomy is a fun and very ancient science. But only now, with modern telescopes and space crafts, we are starting to understand the huge vastness of the universe.
Well intentioned but false. There were many ancient tribes who had maps of the stars and knew about other planets when it should not have been possible. One such device is the Antikythera mechanism. I believe its from ancient greece.
@@shaemarshall5156 why wouldn’t it be possible? Stars are huge and very bright we can see it easily at night, we’ve always used Stars for navigation and probably the first way we navigated
@@YoungBlood507 because it doesnt explain the in depth knowledge that these ancient tribes had. Also, the other guy said "only now with modern telescopes are we starting to understand the vastness of the universe." False. There have BEEN many tribes who mapped the stars. Far beyond what we even knew of 100 years ago. Hence why his statement was incorrect. For some reason, the human population of today hold this ridiculous belief that we are advanced as we have ever been on this planet in this age. Proper research, OUTSIDE of mainstream teachings, will prove otherwise. The information is there for those who seek it.
I love stuff like this. With as many stars and planets out there, it's almost a certainty that SOMEWHERE has intelligent life on it - BUT - with as far away as everything is it gets even more unlikely to ever find each other. PLUS - you have the problem that even if we're sending messages out there, that whoever is listening needs to have the equipment to hear it and to be able to respond. We've only had the technology to listen to outer space for less than 100 years now, but for all we know, aliens could have been sending us radio messages during biblical times and gave up because nobody here at that time could respond. This is why all the sci-fi shows have "warp speed" that goes faster than the speed of light - we still have NO idea how to do that for real yet. Without it, finding aliens would be as likely as a snail in Texas and a snail in New York ever running into each other by accident. Cheers
"Neptune is closest to the Sun" Oh Asia..... The planets are easily remembered with this old saying "My Very Elderly Mother Just Sat Under the North Pole" How does that help, the order is Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto. So BJ is correct, Neptune and Pluto are the outer planets. Just to update from this video, as of January this year Voyager is now about 156 Au's away from us. For a Comparison Pluto is just 40 Au from us so Voyager 1 is already 4 times as far away as Pluto is.
I applaud you for trying to wrap your head around this. I'm big into astronomy and this is all very true. The observable universe is very, very big. Bigger than the human mind can really comprehend.
Keep in mind that "observable universe" just means the parts of the universe that we can see. The entire universe itself is probably much, much larger than that.
@@TheIceMurder2 They're americans. They need everything repeated 100 times before they understand it. Also she has extremely long claws and probably uses caterpillar eyelashes which means required repetitions is 500.
"Astronomy is a humbling experience" wrote Carl Sagan, the astronomer referenced in the video you guys watched, and we know all this because our telescopes are _amazing._ We can actually see all the way to the edge of physics, literally.
Here’s a thought: our sun is a G-type main sequence star, the 2nd most likely class of star that could host planets with potential life to evolve. Despite orbiting the second most likely star for life, here we are. The most likely are thought to be K-type stars, which are orange, cooler, and have longer lifespans than sun-like stars (remaining stable for 18-34 billion years). Get this, they’re just over two times more common out there than stars like our sun. G-type stars only represent 6% of stars, K-types are 13%. There’s no chance that there isn’t other life out there somewhere.
The theory of evolution and all the chances for an info-processing capable species like ours to evolve randomly from the process of evolution puts the chance that we are alone, VERY VERY HIGH. Our existence, when looking at the numbers, is quite literally a miracle that most likely has never occurred anywhere else in the known universe. Then on top of that, the type of star, the size of their moon, a Jupiter like planet nearby to catch asteroids, and countless more variables required not only for the existence of life but also for the sustainably of life. We are most likely alone when it comes to high intelligent beings. Of course there most definitely is maybe microscopic life or even maybe animal life out there. But intelligent agents like us, very unlikely.
Also to point out, the size of our universe is a required variable for the origin of life in the universe at all. So just because of many stars or how big our universe is, doesn’t raise the chances for life out there, the size is simply a necessity for life to exist in the universe at all. This is what they call the teleology of the universe or fine-tuning of the universe for life.
True, No one alive on Earth today is ever likely to visit another planet in our Solar system, not even Mars we are so far away from the Technology needed to do that (effects of Solar Radiation, effects of low gravity, etc) And , without a major breakthrough in Technology, the human race is unlikely to EVER leave the Solar System, or to make contact with another civilisation, of which there are probably thousands. If we could ever invent a propulsion system that could fly close to the speed of light, it would still take something like about 90 years to reach the next Star System - Truly mind blowing :)
I got started with being fascinated with the universe for the same reasons you two experienced in the video - curiosity and awe! I lived in a very remote area as a kid, so the night sky was as dark as it gets. I used to spend hours just staring up at the stars wondering what they were, how they got there, how far away they are etc. To the point where I had neck strain problems as a kid! I also noticed and wondered about how there were different stars visible in winter and summer, and why the moon rose at different times throughout the year etc. Then I became a teenager and asked for a telescope for my birthday! Alongside reading A Brief History of Time, that was one of the most important event in my life as far as giving me an absolutely insatiable lust for knowledge. I used that little 4 1/2" reflector until I wore it out and it fell apart! As an adult, I live in a city, but I get to the dark skies as often as I can, and have spent some money on equipment to help me see and experience all of the weird and wonderful stuff that's out there - and believe me there's plenty! Now that I know more about how things work out there in space, I'm even MORE into it and fascinated by it than when I was a child. It has become an endless hobby for me, reading as much as I can about the universe, and seeing it as much as I can. It's a lifelong type of thing. Once you get into reading about galaxies, clusters, nebulae, stars, planets, black holes, asteroids, comets, orbital mechanics, measurements, our own sun and solar system etc you just get more and more hooked, and the more you want to know. Then you've got a keen interest for life. RUclips is a great platform for astronomy, for the first time in history we can look through expensive telescopes on the other side of the World, for free! Lots of great astronomy and physics channels on here that I watch regulary, such as Deep Sky Videos, SEA, Astrobackyard, John Godier, Astrobiscuit etc. etc. It's a great time to be interested in this stuff, I don't even have to go outside to see the amazing things up in the sky! Learning about the universe is very rewarding for the mind, and even helps with mental health and stress, I really believe that.
The way they can "zoom out" is the way you could draw a map of your yard while you're standing in it. You don't have an above view but you can extrapolate an above view from your surroundings.
Here's one that will blow your mind.... If we took all of the stars in the visible universe and we decided to divide them up equally and give them to every person on the planet, and we use one BB to represent each star, how many BB's would each person on earth receive? Let's say a 50 gallon drum will hold 1 million BB's. If we gave every single man, woman and child on earth 10 drums of BB's (that's 10 million BB's) every singe day, how many day's would it take for everyone to have enough BB's to represent their share of the stars in the universe? According to calculations I did several years ago, every person would have to receive 10 drums of BB's every single day for 19 and a half YEARS to have a BB for every one of their stars.
So the math according to your numbers would look like this 100,000,000 BBs each day for each person multiply that by 7,837,000,000(number of people in the world) times 7,117(19 years 6 months in days) = 5.5775929e+21 That’s what the calculator says idk what that is in numbers lol
They are not literally zooming out using something which has captured all of this. They have put together a 3-D model of what they know so to show just how tiny we are in comparison to the universe. If the universe were a human body....our planet, to the universe, would likely be smaller than an atom is to us. Andromeda is the closest galaxy to ours...and you need a telescope to see it. Asia...yep! we ain't never getting out of here. LOL
Someone actually did the math on this, to a certain level. If the entire universe were the size of our solar system, we would be about 19 Femto meters high. That's 19^-15 meters high. To put that in perspective, not only would we be smaller than an atom, we would be almost as small as a quark.
@@somersetcace1 LOL...this solar system is much larger than our bodies. So I was a bit off on my estimation. I did a good bit of math for mechanical engineering...but I didn't even want to give that one a go. 😂
Not sure if you have checked in your location if there are any visible, or if the light conditions prevent it, but where I live I just need to drive out of town a little (light pollution) on a clear night to see two galaxies in the night sky. When I lived out in the country, I could see them from my back door.
“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.” ― Douglas Adams, The Hitchhiker's Guide to the Galaxy And yet the human brain, about the size of a melon, can form an idea of just how big it is.
@@grabtharshammer you can’t even do that, none of these calculations are accurate, these are just educational guesses, they are a lot of variables they can’t calculate in. And very true it’s impossible to fathom the size of it and that’s just the observable universe which is 13-16 billion years old and has been expanding since the first second. This is why we refer the size of the universe as infinite because it really is, it will never stop expanding and growing in all directions and at the speed of light.
Take a look at the Hubble 'deep field' photographs. They observed a point in the sky with nothing visible and by using Hubble they identified hundreds of galaxies in the tiny bit of sky. There are also some other videos that give you a different perspective of the vast scale of the distances.
hobbypassion: I remember seeing that in a huge spread in National Geographic. I was stunned. It was simply the most beautiful, awe-inspiring thing I'd ever seen
Some of of my favorite photos are of the different nebulae throwing off whole new galaxies. It’s completely insane, and stunningly beautiful, and humbling, and terrifying all at the same time.
So basically, the moral of the story/video is, we are not as big as we think we are. With that said, if we could all just get along, relearn to love, (if you've forgotten), put yourself last, if you want to be 1st and practice being selfless. 👍Oh, and one more thing, treat your fellow humans with dignity & respect. It goes a long way and should make you feel good about yourself. I know it makes me stay positive, smile more and it allows me to talk to strangers. Remember, strangers are just unmet Friends! Love you Both. ✌️❤️🙏
Some 40 + years ago when I was a super nerd (I wouldn’t call myself super nerd anymore, nerd yes but not super) I was BIG into Astronomy. It was, and still remains, a fascinating subject. It leaves you in awe. If you want absolutely gorgeous images of what’s out there checkout the Hames Webb Telescope images; it will blow your mind!!
We Know the Speed of of various wavelengths of Light. The Microwave Background Radiation was thought to be the edge of the Universe because the microwaves have a certain wavelength. I worked on Voyager's Star Tracker back in 74. Voyagers were launched in 1976 and are currently outside of the Solar System
My father also worked on Star Tracker, I'm not sure of the time frame. He was in California and Florida at different times. His name is Len Ortiz, he tested equipment with nitrogen I remember and worked on structural repair and modification as well as fuel systems. Perhaps you're an engineer or other design personnel and never met.
One of the ideas that give me comfort --- at 13:50 " We never gonna get out of here" This will likely mean that the virus that is humanity will never ever infect any significant portion of our galaxy. What a relief.
The question "Is all this research even worth it?" was beautifully addressed in the tv show Babylon 5. The Commander of the titular Space Station had this to say in an interview: Mary Ann Cramer : I have to ask you the same question people back home are asking about space these days. Is it worth it? Should we just pull back? Forget the whole thing as a bad idea, and take care of our own problems, at home. Cmdr. Jeffrey Sinclair : No. We have to stay here. And there's a simple reason why. Ask ten different scientists about the environment, population control, genetics, and you'll get ten different answers, but there's one thing every scientist on the planet agrees on. Whether it happens in a hundred years or a thousand years or a million years, eventually our Sun will grow cold and go out. When that happens, it won't just take us. It'll take Marilyn Monroe, and Lao-Tzu, and Einstein, and Morobuto, and Buddy Holly, and Aristophanes, and - all of this - all of this - was for nothing. Unless we go to the stars.
Put it this way kids. The Milky Way has an elliptical orbit around two blue giants where even the smaller one is 800x the size of our solar system. This cycle takes about 40 years to complete. That being point A to point B, it doesn't include the route around each giant. So as that spin around happens, it creates our extended weather patterns. Something Agriculture aka farmers have known for years. Take a night out, west of D/FW in the gap between Wichita Falls and Bowie, where you don't get urban light pollution and look up. Pack a lunch and camping gear because the show is after the sun goes down.
There are many ways to measure vast distances in the universe. One common technique is to use "standard candles" as a distance marker. It goes something like this: - Each different type of atom will glow and emit specific wavelengths of light when they get really hot. - A device called a spectrum analyzer can be used to look at a light source and measure the wavelength patterns to determine what types of atoms are glowing there. - We know what combination of atoms should be present for different masses of stars when they go supernova, based on the process of radioactive decay in a fusion reaction. - There are different types of supernova. A type 1A supernova has a very specific chemistry, wavelength pattern, and brightness. - The brightness of any light source decreases over distance based on the inverse square law. So, you point a telescope at different bright spots in the sky, measure the pattern of the wavelengths of light that are emitted using a spectrum analyzer, if you detect the wavelength pattern for a type 1A supernova, then you know that it should have a specific brightness per unit of distance based on the inverse square law. You measure how dim the light is from the supernova, and with that you can calculate how far away the supernova is. Scan the sky for numerous type 1A supernovas, and use that to create a map of distances to those specific points.
I LOVE that you are getting into Astronomy!! Common mistake, but *Astrology* refers to the Zodiac. What's your sign, look up your horoscope, do your birth chart stuff. (I'm a Leo!) Tons of fun, but totally different. xD
@@lusiouse right! A galaxy consists of billions of solar systems. Each star is basically it’s own solar system. Most stars we look at today have at least one or more planets orbiting them. There are over 2 trillion individual galaxies each with 100’s of billions of solar systems. They estimate there are at least 200 billion trillion galaxies. That’s 1/5 of a quadrillion. 😂😂😂😂 How could there not be other life out there?
The big question, " how would they be able to see all that?" This is why the Hubble telescope was such a great invention. Hubble is a massive orbital telescope, and we've been using it to map out the observable universe for a few decades now (30 years), but, it's still just shows what we can see based on reflections of light out in the universe. Also Voyager sends information back to earth on what it is getting as well. Takes about 2 days for earth to send and receive info from the probe currently.
Because short term thinking people believed it wasn't worth it. Without public support no politicians were willing to hang their hat on further manned missions to the moon. If we hadn't stopped going in the mid 1970's we would have been on Mars decades ago.
All this information is completely mind blowing and makes you feel so insignificant. - until you realize what everything really is, the entire universe and yourself - then that realization could either drive a person insane or set them free. I haven't figured out yet which way its driven me. need to meditate more.
think about this the four most abundant chemically active elements in space are carbon nitrogen oxygen hydrogen .... guess what the four most abundant elements are in your body (what it's mostly comprised of)? u are truly a child of the universe. we live in the universe but a piece of the universe lives in each of us 🤯
@@dansharp2860 we are conscious, as of now we are the only conscious beings in the universe that we know... that makes us the most significant thing in the universe. "i think therefore I am" if there 8s no conciseness in the universe do it even exist? its our duty to explore the universe... and we will, it is in our nature. that's the meaning of life to learn and share the experience that is consciousness
Hey guys! So you can measure distances with some ease. For example: Time= Distance divided by speed or Time= Distance / speed. We can measure the speed of light so that helps us work out the distance. So to find the distance of something you would do... The speed of light = 299792458 meters per second Distance=Speed x Time. There are other ways to work out distance such as triangulation but i think the speed of light x time equation. Now if you look at the sizes of something like Black holes, that's something quite frightening, lol! Even trying to imagine the size of some of them isn't easy. Not to imagine just how scary they are if you were ever to come across on or if one was heading towards the earth. A great video guys. Have a fantastic day, enjoy!
Voyager 1 is 138 AU's from us and 1 AU is the distance we are from the Sun (not the moon). Light travels at about 186,000 miles per second! The Voyagers, 1 and 2, are travelling at about 11 miles per second. Messages from Voyager 1 take just under 19 hours 6 minutes to reach Earth.
If we ever get the ability to travel all the way to another galaxy, it would have to be something that also allows us to travel all over the universe, like either teleportation or time dilation of some kind. What I never understood was the last part about some places are expanding away from us, and because we are also expanding away from them, the combination makes the difference faster than light, so we will never be able to see it... That's weird to me because the light isn't tethered to the object so all it would have to do is move faster than we are from it's current location, since we are not moving at the speed of light, and light has a constant speed... It's not like being in the back of a truck and throwing a baseball, cuz the object (you) are effecting the speed of the light (the baseball).
The answer I think you are looking for concerning this has to do with the fabric of space time expansion to be correct. You are correct about the speed of light being constant. Keep in mind that the constant is approximately 300,000Km/second. That's distance over time. However, if distance is expanding greater than 300,000Km/Second, meaning the starting point of light and the target point of that light distance is expanding faster than the speed of light then do you think the light will ever get to the target point? Keep in mind, it is not either point that is moving in relation to itself. it is the expansion of time and space itself that is expanding the distance of the two points.
You guys are awesome! Love your reactions, but the proper term in this video is astronomical derived from astronomy, which is the scientific study of the universe vrs. astrological which has to do with the mystic study of astrology having to do with astrological signs such as Leo, Libra, Sagittarius, Gemini, etc.
I had a piece of petrified horn coral I found identified at the museum. They told me it was approximately 380 million years old. When I place it in other people's hands, I ask them to try and even comprehend that amount of time. it really is incomprehensible to us as humans who only live 100 years if we are lucky.
I'm grateful that y'all are watching stuff like this cuz it means more people will get exposure to how truly amazing the fact we exist is. I was lucky and got shown stuff like this as a kid and it still amazes me decades later. The more people excited about our world and universe, the better our hearts and minds become. Who needs virtual reality when reality itself is insanely interesting
To quote Hitchhiker's Guide to the Galaxy: "Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."
We are but a speck of a speck in an ocean of galaxies We are not alone and never have been. Our ancestors rock paintings that showed Star people visiting and are thousands of years old is evidence of that. The only way to escape this universe, is when we graduate from this life and our spirit enters into a new realm which cannot be found anywhere in this universe. Awesome reaction Asia and BJ ❤️
So well said MickeyG, but your words & comments always are so lovely! We appreciate all the love you give us, as well as the Fam! Thanks so much for the super thanks, we love you too ❤️❤️
When you look at how many billions of stars are in our galaxy times billions of galaxies, it is pretty much mathematically impossible for this to be the only planet to have developed complex life
In Laymens terms, the reason they know how to map galaxy is they can measure galaxys by how far away it is. They find out how far by looking at the light coming from that galaxy. The longer the wave length of the light, the further away it is. They call this red shifted. Basically, a blue light from galaxy is close, a red light is further away. They measure how much each galaxy has shifted to measure how far away it is. Also, we have only surveyed 10% of whats our there.
Awesomeness!!! That was very informative and fun watching yalls reaction. Every morning while having coffee i put me on some Asia and BJ to start my day. Thank you for doing what yall do...
That is what telescopes are for, guys; when lights from galaxies or planets hit the telescope that we use on earth, then we know those galaxies or planet are out there and using mathematics, we can see how far those galaxies or planets are👌👍
We aren’t even 1 galaxy, we are literally orbiting only 1 star in a galaxy of billions of other stars…. Each with the potential to have their own system of planets orbiting them…
How fascinating that not only are we self aware as a species, but we can learn and understand our evolution both terrestrial and our cosmos. Magnificent.
Thank you for this video reaction. It`s so mind numbing for me to even imagine. Love always your reactions and insight. Now this makes me think, in the movie "Men in Black", their Galaxy was in a marble around a dogs neck on a collar. Could we be in there. There supposed to be more solar systems that can support life as there are grains of sand on all the planet Earth. totally mind boggling concept. Keep up the great content. Do some Ancient Alien videos, this will open a lot of interest.
To Answer Your Question about How They are Able to Zoom Out like That, All the Known Images That Have been Captured from Hubble and Other Telescopes Have Been Stored and A 3D Model of the Known Universe Can be Created, You Could Basically Zoom In and Out of the Known Universe on Your Computer These Day's
Most things in astronomy are actually public domain and available to everyone. If we look at the new space telescope - the James Webb - some groups pay for priority access which lets them have 6 months with the data before everyone else gets access to it.. but 6 months later you could download it and look at it yourself. There are lots of discoveries the last decade that have come from amateurs going through data released from NASA, ESA or some other space organization.
Easy way to remember the bodies in our solar system. 4 rocks, Mercury, Venus, Earth, Mars and 4 gas giants, Jupiter, Saturn, Uranus, Neptune. Pluto has generally been downgraded from "Planet" status.
The pale blue dot photo was taken as voyager went through Saturns rings. Those rays of light were Saturns rings, and the dot was earth from that perspective. Amazing in my opinion
Optical and radio telescopes are able to capture images of galaxies (you can see galaxies yourself with a decent sized amateur telescope). Astrophysicist can determine size, distance and velocities of galaxies through various means. With this information, along with their location in the night sky, they can create a 3d map of the universe (they haven't actually mapped every galaxy obviously, but enough to get a very detailed understanding of the structure of the universe). Galaxies that are measured within a certain distance form others are grouped into clusters, and those clusters are grouped into clusters with others that are within a certain distance from them.
For easy math, when they talk about light years, The voyage probe is going about 36,000 mph! And even at that speed, it would take 20,000 years to travel 1 light year
The new james webb space telescope is the first telescope designed to detect artificial light sources. But its also capable of seeing further than any current technology. Its mission is to study all the exo planets (about 163 currently) we have discovered to see if they have alien life.
I've already seen so many reacts to this video, but no one has addressed what I think is the most important statement in this video. "we can discover TOGETHER". No country can do this alone. When we finally learn to work together without prejudice and not money rule everything then we will explore and invent things that are beyond our imagination.
Yes, these facts are mind blowing. But what also amazes me, is that the sphere that describes the eath and moon system, by volume, would fit 8 times into the volume of the sun.
Just to add some insight...@9:12 in the video when your discussing people traveling to Proxima Centauri, they weren't referring to the humans traveling there not existing by the time of reaching it, but the fact that the star would be long dead by the time anybody got there. The galaxy is so vast that many things have long blown up or died but the light hasn't had time to reach us to let us know that it happened yet.
The mnemonic to remember the planets is: My Very Elegant Mother Just Served Us Nachos. The first letter of each word stands for a different planet, in the order from closest to the Sun to the farthest one: Mercury Venus Earth (3rd rock!) Mars Jupiter Saturn Uranus Neptune (The dwarf planet Pluto spends most of its time beyond the orbit of Neptune.)
Just in case nobody else has pointed it out, it's astronomy that you learn about in school, not astrology. Astrology is using star signs and the position of planets to try and make predictions about the future. Astronomy is the actual study of astral bodies in space. They did say that Voyager 1 is 138x farther away from us than the sun. BJ is stuck thinking about how much farther away Mars is compared to the moon. They did not say 100 galaxies, they said 100 groups of galaxies. There are far more than 100 galaxies there in the Virgo super cluster. More like thousands of galaxies, at least. You couldn't have been following astronomy too closely if you don't know about this stuff. They use telescopes to find these things, as well as interpretations of data. None of it is completely accurate, but it's a close approximation which will become better defined with time. Also, the word is astronomical, not astrological. Again, wrong thing. One is science, the other is not. Neptune is not closest to the sun, Mercury is. Venus is the second closest. Neptune is the farthest out of the 8 famous planets. Pluto, whether you consider it a planet or not, is then farther out than Neptune most of the time, though sometimes it is closer. There are also other worlds in the solar system that some consider to be planets and others do not, to the point where there could be about 600 planets orbiting our sun. When you say that Neptune and Pluto are the farthest out planets in our galaxy, you mean in our solar system. As I said before, though, there are other planet-like bodies orbiting the sun even father out than those. These days we've even seen planets around other stars.
6:57 theres so much space out there in space between everything you could travel in a straight line from one edge of the observable universe to the other and NOT run into anything at all. Space is that spacious
The Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and I still think of it as a planet, Pluto. When I took Astronomy in college and Pluto was still considered a planet the simple phrase was "My Very Educated Mother Just Served Us Nine Pies. "
The kind of mind numbing size that makes you realise that the human species may come and go from the universe, but no other alien life would never know we ever existed, and millions of other alien civilisations may do the same. VERY humbling!
6:25 When you're talking about us being the only planet we know of that has life, Arthur C Clarke (the author of 2001: A Space Odyssey) said it best: "Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying."
The way I look at it is there can never be a wall in the universe because there’s always something on the other side it can never end. That blows my mind.
I think the writer Douglas Adams summed it up in 'The Hitchhikers Guide to the Galaxy': “Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space. Listen; when you're thinking big, think bigger than the biggest thing ever and then some. Much bigger than that in fact, really amazingly immense, a totally stunning size, real 'wow, that's big', time. It's just so big that by comparison, bigness itself looks really titchy. Gigantic multiplied by colossal multiplied by staggeringly huge is the sort of concept we're trying to get across here..”
NGC is an identifier for each galaxy. It is the New General Catalog. Basically, a long time ago, an astronomical was observing space and jotted down what object is where in the sky and cataloged that object. So, for example, the NGC 6744 would be the 6744th object I. The catalog of all the observed objects in space.
Actually guys AU is the distance between the earth to the sun, she was right the first time. Also Pluto is the furthest planet then Neptune and Uranus are closer to the sun than Pluto. Planets in order from closest to furthest from the sun: The Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
It is pretty crazy. I feel as humans, we would never be able to travel such distance, by simply only traveling at the speed of light. I think the only way for humans to travel, would be to figure out how to manipulate space instead. Oh, how they measure distances and stuff in space is by this: Radar - measuring distances in our solar system. Parallax - measuring distances to nearby stars. Cepheids - measuring distances in our Galaxy and to nearby galaxies. Supernovae - measuring distances to other galaxies. Redshift and Hubble's Law - measuring distances to objects far, far away.
The Voyager spacecrafts were both launched in 1977, one in August and one in September. (The September one got to Jupiter first!) They were launched at that time because the planets would line up perfectly by the time each spacecraft reached important locations like the gas giant planets. Each planet provided a gravity boost to fling the spacecraft towards the future location of the next planet. Voyager 1 visited Jupiter and Saturn. Voyager 2 also visited these two planets but also went on to fly by Uranus (pronounced “your ahn us” with the accent on the first syllable) and Neptune. It is so far the only spacecraft to visit the outer two gas giants. 45 years later, the Voyager spacecrafts are approaching the true boundary where our solar system ends and interstellar space begins. The Pale Blue Dot photo was taken in 1990, only 13 years after launch and 10 years after its flyby of Saturn. By contrast, Voyager 2 flew by beautiful blue Neptune in 1989. So, the Pale Blue Dot photo was taken in space past the orbit of our 8th planet, but still inside the orbit of Pluto.
If I remember correctly, both the Voyager probes carry a gold disk with information about Earth and depictions of Humanity on it. Of course, by the time any other intelligent, space faring species finds it, we will likely be extinct.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto (no longer considered a planet though)... Order of the planets from the sun outward. ♥️
This was a great reaction thank you for doing it! I find the conversations you were having when your mind tries to wrap around the real scale of how big things are, is so interesting. Hope you enjoyed it as well!
Cali, shoot we really, really enjoyed it! So interesting, we were mind blown on a lot of the info. Thanks, great suggestion!!
I was involved in Hybrid Microelectronics design. Our business was with Photon and Electrons, the other end of the Universe.
@@AsiaandBJReact Ill never put a video down that inspires people to start talking, for that the video deserves commendation. However i would take some of it with a pinch of salt, the original video while informative, has an incredible amount of speculation in it masked as fact. In fairness i suspect its to simply help the viewer understand the concepts easier, but at the same time its very misleading and ultimately delivers misinformation which doesn't really help anyone. I'll give you a single example (of which there are many), he said "Any Civilization outside this space would be unaware of our presence". For one, he cannot possibly know that, unless he has discovered alien life it is an assumption and pure speculation. Secondly, any civilization that was technologically advanced enough would not be using radio to communicate, its too slow. When you are dealing with the LY scale and civilizations that explore and traverse these kinds of distances, Radio would be the equivalent of smoke signals using a match. Admittedly, this is speculation on my part, but you would think they would use somthing like quantum entanglement for data transmission. Entanglement would negate distance as a hurdle, regardless of the scale. Hell, we as humans havent even visited another planet yet and we know how to make entanglement work. A single assumption that any other life in the universe would follow the exact same technological path a humans is very arrogant to say the least.
Now that you've watched this one and realize the enormity up the visible universe, you should check out "Origin: probability of a single protein forming by chance" by Philip C. Religious or not it's hard to wrap your head around it. The idea of a higher intelligence or God is just inescapable.
Intuitively, we tend to think that there are as many stars out there as there are grains of sand in a fire bucket...maybe. In fact, here are more than there are grains of sand on this entire planet...by several orders of magnitude. And the nearest one is 4.2 light years away. Absolutely mind-blowing.
Asia, think about Voyager 1 this way: It was launched on Sept 5, 1977 - 45 years ago! - and has been traveling at 38,000 miles per hour! Yet it's only gone that far.

We have photos of galaxies that are billions of light years away too...those could not even exist present day that we know of
I remember when Voyager was spun to take the picture of earth, in schools and on the news worldwide everyone was asked if they were able to participate in a global event. At a set time walk outside look up smile and wave. It was 9 PM ish I recall I was allowed to stay up a little past my bedtime. Me and my brothers and sisters all walked out and did it. Later I realized how cool it was that I looked up and down the block and seen people I knew joining in, then realizing people around the world in every time zone in countries Id only read about. People I'd never know where sharing in that with us. A beautiful moment of global unity. We used to have those then. Not so much anymore with the global elite tarring it all down.
That must be a cool thing to think about everytime you see the Pale Blue Dot photo
You're thinking of the Cassini probe to Saturn. Still a fantastic event.

Elon Musk, along with the rest of the billionaires and international cooperation for the JWST are points that objectively tear apart your last sentence. The Artemis mission is scheduled for like right now and you've gone and screwed up what otherwise was a beautiful memory and message with utter BS. Good job. 👍
did they feather it all down too?
Here's the idea going in the opposite direction: Every cell in our body contains 2 meters of DNA. Our bodies are comprised of about 30 Trillion cells. The speed of light is almost exactly a billion kilometers per hour. And that means it would take light about 30 hours to travel the length of the DNA inside each of our bodies. From tiny to huge, the universe is worth paying attention to.
You guys should consider doing the Veritasium video on what trees are made of. His stuff is super well explained, but fascinating. And he's solid in his facts. He gets tested by the best--he has highly educated viewers keeping tabs on him. :-)
That's true and they called him out on one of his sponsored videos where he is less than totally honest, head doing amazing work of bringing the sciences to the masses
Thank you for sharing this.
That bit about the cumulative length of DNA in a person’s body just sent me for a trip. It always amazes me when a handful of concepts I understand rationally are reframed in a novel way, such that I can immediately sense my entire instinctual understanding of the universe reshaping itself.
Care to explain that geometry or are you just repeating something you don't actually understand?
I can't even see straight right now. What's crazy to think about is as big as the universe is, its equally as mind blowing if you start looking in the opposite direction into the molecules that make up everything we can observe. How small everything gets.
Molecules are big in comparison to quarks, electrons, & neutrinos which are a million times smaller than an electron.
Yea that's crazy because we don't know what's up there, and we don't know what's down here like under the oceans. We don't know the very big, but not the very small either
Quantum Physics practically breaks our understanding of the Universe itself...
@@roxee57 You might even say a million times smaller than 'the' electron, if you follow the idea that only one electron exists in multiple places. And, in fact, if you consider the positron as an electron that's going backward through time, then all positrons and electrons are the same particle swinging forward and backward through time. I personally don't think this is right, but it's fun to consider.
Yup, zoom in far enough and suddenly an atom is as big as a planet
"we never guna get out of here" best line in the vid,, too funny, still laughing 🤣🤣🤣🤣
Made me laugh too! Funny!
My favorite comment, in that moment you could hear the humor and a little sadness.
also probably true.
I love hearing this from a layman's perspective.
What they said about it taking 20 minutes at lightspeed for a message to go from Earth to Mars: The Mars rovers are the same so when they want to send a computer command to the Mars rovers it takes 20 minutes for the message to get there and 20 minutes for the response to get back to Earth. Can you imagine everytime you did something on your computer it took 40 minutes for your computer to respond to your command? It makes things complicated!
Why, it would be like using a 56K Modem way back in the day to communicate from my house to the school computer! 🙃
@@GanciEnglishIdioms also every now and then, someone picked up the phone and you lose connection XD
It’s actually wrong information, it does not take light 20 minutes to travel to mars, it only takes 3 minutes, I’m not sure where he got 20 minutes. Since it takes only 8 minutes for light to hit the earth from the sun and Mars is much closer.
@@YoungBlood507 The minimum amount of time is ~4 minutes, the maximum is 20 minutes depending on the position of the planets. The distance changes as the planets orbit.

Astronomy is a fun and very ancient science. But only now, with modern telescopes and space crafts, we are starting to understand the huge vastness of the universe.
Well intentioned but false. There were many ancient tribes who had maps of the stars and knew about other planets when it should not have been possible. One such device is the Antikythera mechanism. I believe its from ancient greece.
@@shaemarshall5156 Nothing I said is false. What you said doesn't contradict what I said.
@@shaemarshall5156 why wouldn’t it be possible? Stars are huge and very bright we can see it easily at night, we’ve always used Stars for navigation and probably the first way we navigated
@@YoungBlood507 because it doesnt explain the in depth knowledge that these ancient tribes had. Also, the other guy said "only now with modern telescopes are we starting to understand the vastness of the universe." False. There have BEEN many tribes who mapped the stars. Far beyond what we even knew of 100 years ago. Hence why his statement was incorrect. For some reason, the human population of today hold this ridiculous belief that we are advanced as we have ever been on this planet in this age. Proper research, OUTSIDE of mainstream teachings, will prove otherwise. The information is there for those who seek it.
I love stuff like this. With as many stars and planets out there, it's almost a certainty that SOMEWHERE has intelligent life on it - BUT - with as far away as everything is it gets even more unlikely to ever find each other. PLUS - you have the problem that even if we're sending messages out there, that whoever is listening needs to have the equipment to hear it and to be able to respond. We've only had the technology to listen to outer space for less than 100 years now, but for all we know, aliens could have been sending us radio messages during biblical times and gave up because nobody here at that time could respond. This is why all the sci-fi shows have "warp speed" that goes faster than the speed of light - we still have NO idea how to do that for real yet. Without it, finding aliens would be as likely as a snail in Texas and a snail in New York ever running into each other by accident.
Cheers
Hey Colonel B, Thanks! Appreciate always showing us love with your comment and super thanks! ❤️❤️
"Neptune is closest to the Sun" Oh Asia..... The planets are easily remembered with this old saying "My Very Elderly Mother Just Sat Under the North Pole" How does that help, the order is Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto. So BJ is correct, Neptune and Pluto are the outer planets. Just to update from this video, as of January this year Voyager is now about 156 Au's away from us. For a Comparison Pluto is just 40 Au from us so Voyager 1 is already 4 times as far away as Pluto is.
I applaud you for trying to wrap your head around this. I'm big into astronomy and this is all very true. The observable universe is very, very big. Bigger than the human mind can really comprehend.
Asia: "We're never going to get out of here". OMG LMAO!!!! You two are adorable together. I love your reactions.
Asia's great!
Telling it like it is!
I loved that! “We’re never going to get out of here!” It made me laugh. Thank you.
Keep in mind that "observable universe" just means the parts of the universe that we can see. The entire universe itself is probably much, much larger than that.
Yea, the video covered that pretty well.
The video already explained that...

"Astronomy is a humbling experience" wrote Carl Sagan, the astronomer referenced in the video you guys watched, and we know all this because our telescopes are _amazing._ We can actually see all the way to the edge of physics, literally.
Here’s a thought: our sun is a G-type main sequence star, the 2nd most likely class of star that could host planets with potential life to evolve. Despite orbiting the second most likely star for life, here we are. The most likely are thought to be K-type stars, which are orange, cooler, and have longer lifespans than sun-like stars (remaining stable for 18-34 billion years). Get this, they’re just over two times more common out there than stars like our sun. G-type stars only represent 6% of stars, K-types are 13%. There’s no chance that there isn’t other life out there somewhere.
well there is a chance that there isn't, albeit very small
The theory of evolution and all the chances for an info-processing capable species like ours to evolve randomly from the process of evolution puts the chance that we are alone, VERY VERY HIGH. Our existence, when looking at the numbers, is quite literally a miracle that most likely has never occurred anywhere else in the known universe. Then on top of that, the type of star, the size of their moon, a Jupiter like planet nearby to catch asteroids, and countless more variables required not only for the existence of life but also for the sustainably of life. We are most likely alone when it comes to high intelligent beings. Of course there most definitely is maybe microscopic life or even maybe animal life out there. But intelligent agents like us, very unlikely.
Also to point out, the size of our universe is a required variable for the origin of life in the universe at all. So just because of many stars or how big our universe is, doesn’t raise the chances for life out there, the size is simply a necessity for life to exist in the universe at all. This is what they call the teleology of the universe or fine-tuning of the universe for life.
This was very interesting. I had no idea how little we truly are. I love your comment, We are never getting outta here.😂😂😂
"We're never getting out of here" is the best line of the day!
True, No one alive on Earth today is ever likely to visit another planet in our Solar system, not even Mars we are so far away from the Technology needed to do that (effects of Solar Radiation, effects of low gravity, etc) And , without a major breakthrough in Technology, the human race is unlikely to EVER leave the Solar System, or to make contact with another civilisation, of which there are probably thousands. If we could ever invent a propulsion system that could fly close to the speed of light, it would still take something like about 90 years to reach the next Star System - Truly mind blowing :)
Haha facts!
A feeling of resignation.
"The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself"

No matter how big you think the universe is, it's even bigger.
Human comprehension completely breaks down after we go beyond our own solar system.
I got started with being fascinated with the universe for the same reasons you two experienced in the video - curiosity and awe! I lived in a very remote area as a kid, so the night sky was as dark as it gets. I used to spend hours just staring up at the stars wondering what they were, how they got there, how far away they are etc. To the point where I had neck strain problems as a kid! I also noticed and wondered about how there were different stars visible in winter and summer, and why the moon rose at different times throughout the year etc. Then I became a teenager and asked for a telescope for my birthday! Alongside reading A Brief History of Time, that was one of the most important event in my life as far as giving me an absolutely insatiable lust for knowledge. I used that little 4 1/2" reflector until I wore it out and it fell apart!
As an adult, I live in a city, but I get to the dark skies as often as I can, and have spent some money on equipment to help me see and experience all of the weird and wonderful stuff that's out there - and believe me there's plenty! Now that I know more about how things work out there in space, I'm even MORE into it and fascinated by it than when I was a child. It has become an endless hobby for me, reading as much as I can about the universe, and seeing it as much as I can.
It's a lifelong type of thing. Once you get into reading about galaxies, clusters, nebulae, stars, planets, black holes, asteroids, comets, orbital mechanics, measurements, our own sun and solar system etc you just get more and more hooked, and the more you want to know. Then you've got a keen interest for life. RUclips is a great platform for astronomy, for the first time in history we can look through expensive telescopes on the other side of the World, for free! Lots of great astronomy and physics channels on here that I watch regulary, such as Deep Sky Videos, SEA, Astrobackyard, John Godier, Astrobiscuit etc. etc. It's a great time to be interested in this stuff, I don't even have to go outside to see the amazing things up in the sky!
Learning about the universe is very rewarding for the mind, and even helps with mental health and stress, I really believe that.
The way they can "zoom out" is the way you could draw a map of your yard while you're standing in it. You don't have an above view but you can extrapolate an above view from your surroundings.
Here's one that will blow your mind.... If we took all of the stars in the visible universe and we decided to divide them up equally and give them to every person on the planet, and we use one BB to represent each star, how many BB's would each person on earth receive? Let's say a 50 gallon drum will hold 1 million BB's. If we gave every single man, woman and child on earth 10 drums of BB's (that's 10 million BB's) every singe day, how many day's would it take for everyone to have enough BB's to represent their share of the stars in the universe? According to calculations I did several years ago, every person would have to receive 10 drums of BB's every single day for 19 and a half YEARS to have a BB for every one of their stars.
What’s a BB?
@@Worstestvideos I think it's a small little ball they use in Airsoft guns.
So the math according to your numbers would look like this
100,000,000 BBs each day for each person multiply that by 7,837,000,000(number of people in the world) times 7,117(19 years 6 months in days) = 5.5775929e+21
That’s what the calculator says idk what that is in numbers lol
They are not literally zooming out using something which has captured all of this. They have put together a 3-D model of what they know so to show just how tiny we are in comparison to the universe. If the universe were a human body....our planet, to the universe, would likely be smaller than an atom is to us. Andromeda is the closest galaxy to ours...and you need a telescope to see it. Asia...yep! we ain't never getting out of here. LOL
Someone actually did the math on this, to a certain level. If the entire universe were the size of our solar system, we would be about 19 Femto meters high. That's 19^-15 meters high. To put that in perspective, not only would we be smaller than an atom, we would be almost as small as a quark.

Not sure if you have checked in your location if there are any visible, or if the light conditions prevent it, but where I live I just need to drive out of town a little (light pollution) on a clear night to see two galaxies in the night sky. When I lived out in the country, I could see them from my back door.

@@grabtharshammer you can’t even do that, none of these calculations are accurate, these are just educational guesses, they are a lot of variables they can’t calculate in. And very true it’s impossible to fathom the size of it and that’s just the observable universe which is 13-16 billion years old and has been expanding since the first second. This is why we refer the size of the universe as infinite because it really is, it will never stop expanding and growing in all directions and at the speed of light.
“We’re never gonna get out of here”
I haven’t laughed that hard in a long time. 😂
You can see galaxies at night because there's no way the night sky is filled up with stars like that.
Take a look at the Hubble 'deep field' photographs. They observed a point in the sky with nothing visible and by using Hubble they identified hundreds of galaxies in the tiny bit of sky. There are also some other videos that give you a different perspective of the vast scale of the distances.
hobbypassion: I remember seeing that in a huge spread in National Geographic. I was stunned. It was simply the most beautiful, awe-inspiring thing I'd ever seen
Some of of my favorite photos are of the different nebulae throwing off whole new galaxies. It’s completely insane, and stunningly beautiful, and humbling, and terrifying all at the same time.
So basically, the moral of the story/video is, we are not as big as we think we are. With that said, if we could all just get along, relearn to love, (if you've forgotten), put yourself last, if you want to be 1st and practice being selfless. 👍Oh, and one more thing, treat your fellow humans with dignity & respect. It goes a long way and should make you feel good about yourself. I know it makes me stay positive, smile more and it allows me to talk to strangers. Remember, strangers are just unmet Friends!

We Know the Speed of of various wavelengths of Light. The Microwave Background Radiation was thought to be the edge of the Universe because the microwaves have a certain wavelength.

If you put the star Betelgeuse where the sun is, Betelgeuse would engulf the orbit of Jupiter. Betelgeuse a big boi.
The question "Is all this research even worth it?" was beautifully addressed in the tv show Babylon 5. The Commander of the titular Space Station had this to say in an interview:
Mary Ann Cramer : I have to ask you the same question people back home are asking about space these days. Is it worth it? Should we just pull back? Forget the whole thing as a bad idea, and take care of our own problems, at home.
Cmdr. Jeffrey Sinclair : No. We have to stay here. And there's a simple reason why. Ask ten different scientists about the environment, population control, genetics, and you'll get ten different answers, but there's one thing every scientist on the planet agrees on. Whether it happens in a hundred years or a thousand years or a million years, eventually our Sun will grow cold and go out. When that happens, it won't just take us. It'll take Marilyn Monroe, and Lao-Tzu, and Einstein, and Morobuto, and Buddy Holly, and Aristophanes, and - all of this - all of this - was for nothing. Unless we go to the stars.
That show is fantastic, despite the lack of budget in the first season. It's still relevant to this day.
Put it this way kids. The Milky Way has an elliptical orbit around two blue giants where even the smaller one is 800x the size of our solar system. This cycle takes about 40 years to complete. That being point A to point B, it doesn't include the route around each giant. So as that spin around happens, it creates our extended weather patterns. Something Agriculture aka farmers have known for years. Take a night out, west of D/FW in the gap between Wichita Falls and Bowie, where you don't get urban light pollution and look up. Pack a lunch and camping gear because the show is after the sun goes down.
LOL "We're Never gonna get outta here!" The line of the video! My sentiments exactly 😀
The only planet ?
As someone said before "it would a waste of space"
There are many ways to measure vast distances in the universe. One common technique is to use "standard candles" as a distance marker. It goes something like this:
- Each different type of atom will glow and emit specific wavelengths of light when they get really hot.
- A device called a spectrum analyzer can be used to look at a light source and measure the wavelength patterns to determine what types of atoms are glowing there.
- We know what combination of atoms should be present for different masses of stars when they go supernova, based on the process of radioactive decay in a fusion reaction.
- There are different types of supernova. A type 1A supernova has a very specific chemistry, wavelength pattern, and brightness.
- The brightness of any light source decreases over distance based on the inverse square law.
So, you point a telescope at different bright spots in the sky, measure the pattern of the wavelengths of light that are emitted using a spectrum analyzer, if you detect the wavelength pattern for a type 1A supernova, then you know that it should have a specific brightness per unit of distance based on the inverse square law. You measure how dim the light is from the supernova, and with that you can calculate how far away the supernova is. Scan the sky for numerous type 1A supernovas, and use that to create a map of distances to those specific points.
I LOVE that you are getting into Astronomy!! Common mistake, but *Astrology* refers to the Zodiac. What's your sign, look up your horoscope, do your birth chart stuff. (I'm a Leo!) Tons of fun, but totally different. xD
yea that and galaxies arent the same as solar systems ,, and mercury is the closest planet to the sun lol
@@lusiouse right! A galaxy consists of billions of solar systems. Each star is basically it’s own solar system. Most stars we look at today have at least one or more planets orbiting them. There are over 2 trillion individual galaxies each with 100’s of billions of solar systems. They estimate there are at least 200 billion trillion galaxies. That’s 1/5 of a quadrillion. 😂😂😂😂 How could there not be other life out there?
The big question, " how would they be able to see all that?" This is why the Hubble telescope was such a great invention. Hubble is a massive orbital telescope, and we've been using it to map out the observable universe for a few decades now (30 years), but, it's still just shows what we can see based on reflections of light out in the universe.
Also Voyager sends information back to earth on what it is getting as well. Takes about 2 days for earth to send and receive info from the probe currently.
Because short term thinking people believed it wasn't worth it. Without public support no politicians were willing to hang their hat on further manned missions to the moon. If we hadn't stopped going in the mid 1970's we would have been on Mars decades ago.
All this information is completely mind blowing and makes you feel so insignificant. - until you realize what everything really is, the entire universe and yourself - then that realization could either drive a person insane or set them free. I haven't figured out yet which way its driven me. need to meditate more.
think about this the four most abundant chemically active elements in space are carbon nitrogen oxygen hydrogen .... guess what the four most abundant elements are in your body (what it's mostly comprised of)?
u are truly a child of the universe. we live in the universe but a piece of the universe lives in each of us 🤯
I'm at the point where I've chosen to be set free, because even if that means I'm also insane at least I'm free 💃🥰😍🙏😁🥳🎉
Take heart. We might be insignificant on a universe scale but there is still meaning to life if you want there to be.
@@dansharp2860 we are conscious, as of now we are the only conscious beings in the universe that we know... that makes us the most significant thing in the universe. "i think therefore I am" if there 8s no conciseness in the universe do it even exist? its our duty to explore the universe... and we will, it is in our nature. that's the meaning of life to learn and share the experience that is consciousness
those zoomed out images are made from digital mapping. figuring distance and direction, the map is constructed
Hearing people not know that this stuff exists is mildly concerning.
Hey guys!
So you can measure distances with some ease.
For example: Time= Distance divided by speed or Time= Distance / speed.
We can measure the speed of light so that helps us work out the distance.
So to find the distance of something you would do...
The speed of light = 299792458 meters per second
Distance=Speed x Time.
There are other ways to work out distance such as triangulation but i think the speed of light x time equation.
Now if you look at the sizes of something like Black holes, that's something quite frightening, lol!
Even trying to imagine the size of some of them isn't easy.
Not to imagine just how scary they are if you were ever to come across on or if one was heading towards the earth.
A great video guys.
Have a fantastic day, enjoy!
Absolutely mind boggling.
The universe is expanding at the speed of light every second.
I feel very very small after that.
Faster than light as it's space expanding
Voyager 1 is 138 AU's from us and 1 AU is the distance we are from the Sun (not the moon). Light travels at about 186,000 miles per second! The Voyagers, 1 and 2, are travelling at about 11 miles per second. Messages from Voyager 1 take just under 19 hours 6 minutes to reach Earth.
If we ever get the ability to travel all the way to another galaxy, it would have to be something that also allows us to travel all over the universe, like either teleportation or time dilation of some kind. What I never understood was the last part about some places are expanding away from us, and because we are also expanding away from them, the combination makes the difference faster than light, so we will never be able to see it... That's weird to me because the light isn't tethered to the object so all it would have to do is move faster than we are from it's current location, since we are not moving at the speed of light, and light has a constant speed... It's not like being in the back of a truck and throwing a baseball, cuz the object (you) are effecting the speed of the light (the baseball).
There isn't a lot of reason to travel to another galaxy.
The answer I think you are looking for concerning this has to do with the fabric of space time expansion to be correct.
You are correct about the speed of light being constant. Keep in mind that the constant is approximately 300,000Km/second. That's distance over time. However, if distance is expanding greater than 300,000Km/Second, meaning the starting point of light and the target point of that light distance is expanding faster than the speed of light then do you think the light will ever get to the target point? Keep in mind, it is not either point that is moving in relation to itself. it is the expansion of time and space itself that is expanding the distance of the two points.
"We aint ever gonna get out of here!"...HAHAHA...that made me laugh hard..... This was great thanks ya'll!
You guys are awesome! Love your reactions, but the proper term in this video is astronomical derived from astronomy, which is the scientific study of the universe vrs. astrological which has to do with the mystic
study of astrology having to do with astrological signs such as Leo, Libra, Sagittarius, Gemini, etc.
I had a piece of petrified horn coral I found identified at the museum. They told me it was approximately 380 million years old. When I place it in other people's hands, I ask them to try and even comprehend that amount of time. it really is incomprehensible to us as humans who only live 100 years if we are lucky.
Crazy to think about just crazy
the biggest laugh I've had in a long time is when you said: "we"re never gone a get out of here". Love you guys.
Though amazing to think that we've worked out where here actually is now!
Just as a quick heads up.
Astrology: pseudoscience with your star sign and stuff.
Astronomy: study of the universe.
"Two possibilities exist: we are either alone in the universe or we ar not both are equally terrifying." Arthur C Clarke
I'm grateful that y'all are watching stuff like this cuz it means more people will get exposure to how truly amazing the fact we exist is. I was lucky and got shown stuff like this as a kid and it still amazes me decades later. The more people excited about our world and universe, the better our hearts and minds become.
Who needs virtual reality when reality itself is insanely interesting
This is freakin' awesome! You guys need to do more stuff like this.
To quote Hitchhiker's Guide to the Galaxy: "Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."
We are but a speck of a speck in an ocean of galaxies We are not alone and never have been. Our ancestors rock paintings that showed Star people visiting and are thousands of years old is evidence of that. The only way to escape this universe, is when we graduate from this life and our spirit enters into a new realm which cannot be found anywhere in this universe. Awesome reaction Asia and BJ ❤️
So well said MickeyG, but your words & comments always are so lovely! We appreciate all the love you give us, as well as the Fam! Thanks so much for the super thanks, we love you too ❤️❤️
When you look at how many billions of stars are in our galaxy times billions of galaxies, it is pretty much mathematically impossible for this to be the only planet to have developed complex life
@@TonyM1961 Yes you are so right Tony.
In Laymens terms, the reason they know how to map galaxy is they can measure galaxys by how far away it is. They find out how far by looking at the light coming from that galaxy. The longer the wave length of the light, the further away it is. They call this red shifted. Basically, a blue light from galaxy is close, a red light is further away. They measure how much each galaxy has shifted to measure how far away it is. Also, we have only surveyed 10% of whats our there.
Awesomeness!!! That was very informative and fun watching yalls reaction. Every morning while having coffee i put me on some Asia and BJ to start my day. Thank you for doing what yall do...
That is what telescopes are for, guys; when lights from galaxies or planets hit the telescope that we use on earth, then we know those galaxies or planet are out there and using mathematics, we can see how far those galaxies or planets are👌👍
We aren’t even 1 galaxy, we are literally orbiting only 1 star in a galaxy of billions of other stars…. Each with the potential to have their own system of planets orbiting them…
How fascinating that not only are we self aware as a species, but we can learn and understand our evolution both terrestrial and our cosmos.
Magnificent.
Thank you for this video reaction. It`s so mind numbing for me to even imagine. Love always your reactions and insight. Now this makes me think, in the movie "Men in Black", their Galaxy was in a marble around a dogs neck on a collar. Could we be in there. There supposed to be more solar systems that can support life as there are grains of sand on all the planet Earth. totally mind boggling concept. Keep up the great content. Do some Ancient Alien videos, this will open a lot of interest.
To Answer Your Question about How They are Able to Zoom Out like That, All the Known Images That Have been Captured from Hubble and Other Telescopes Have Been Stored and A 3D Model of the Known Universe Can be Created, You Could Basically Zoom In and Out of the Known Universe on Your Computer These Day's
The aren't zooming out from a picture we've taken. They can measure how far a galaxy is and then make a model of the galaxy clusters.
Most things in astronomy are actually public domain and available to everyone. If we look at the new space telescope - the James Webb - some groups pay for priority access which lets them have 6 months with the data before everyone else gets access to it.. but 6 months later you could download it and look at it yourself. There are lots of discoveries the last decade that have come from amateurs going through data released from NASA, ESA or some other space organization.
Easy way to remember the bodies in our solar system. 4 rocks, Mercury, Venus, Earth, Mars and 4 gas giants, Jupiter, Saturn, Uranus, Neptune. Pluto has generally been downgraded from "Planet" status.
The pale blue dot photo was taken as voyager went through Saturns rings. Those rays of light were Saturns rings, and the dot was earth from that perspective. Amazing in my opinion
Optical and radio telescopes are able to capture images of galaxies (you can see galaxies yourself with a decent sized amateur telescope). Astrophysicist can determine size, distance and velocities of galaxies through various means. With this information, along with their location in the night sky, they can create a 3d map of the universe (they haven't actually mapped every galaxy obviously, but enough to get a very detailed understanding of the structure of the universe).
Galaxies that are measured within a certain distance form others are grouped into clusters, and those clusters are grouped into clusters with others that are within a certain distance from them.
For easy math, when they talk about light years,
The voyage probe is going about 36,000 mph! And even at that speed, it would take 20,000 years to travel 1 light year
The new james webb space telescope is the first telescope designed to detect artificial light sources. But its also capable of seeing further than any current technology. Its mission is to study all the exo planets (about 163 currently) we have discovered to see if they have alien life.
I've already seen so many reacts to this video, but no one has addressed what I think is the most important statement in this video. "we can discover TOGETHER". No country can do this alone. When we finally learn to work together without prejudice and not money rule everything then we will explore and invent things that are beyond our imagination.
"We're never gunna get out of here" - Best comment, ever.
The thing that threw me as a child was. There are more galaxies in space than grains of sand on on the Earth. It shows you how big it really is.
Yes, these facts are mind blowing. But what also amazes me, is that the sphere that describes the eath and moon system, by volume, would fit 8 times into the volume of the sun.
Just to add some insight...@9:12 in the video when your discussing people traveling to Proxima Centauri, they weren't referring to the humans traveling there not existing by the time of reaching it, but the fact that the star would be long dead by the time anybody got there. The galaxy is so vast that many things have long blown up or died but the light hasn't had time to reach us to let us know that it happened yet.
A lot of the stars we see in the night sky no longer exist.
The mnemonic to remember the planets is: My Very Elegant Mother Just Served Us Nachos. The first letter of each word stands for a different planet, in the order from closest to the Sun to the farthest one:
Mercury
Venus
Earth (3rd rock!)
Mars
Jupiter
Saturn
Uranus
Neptune
(The dwarf planet Pluto spends most of its time beyond the orbit of Neptune.)
Just in case nobody else has pointed it out, it's astronomy that you learn about in school, not astrology. Astrology is using star signs and the position of planets to try and make predictions about the future. Astronomy is the actual study of astral bodies in space.
They did say that Voyager 1 is 138x farther away from us than the sun. BJ is stuck thinking about how much farther away Mars is compared to the moon.
They did not say 100 galaxies, they said 100 groups of galaxies. There are far more than 100 galaxies there in the Virgo super cluster. More like thousands of galaxies, at least.
You couldn't have been following astronomy too closely if you don't know about this stuff. They use telescopes to find these things, as well as interpretations of data. None of it is completely accurate, but it's a close approximation which will become better defined with time. Also, the word is astronomical, not astrological. Again, wrong thing. One is science, the other is not.
Neptune is not closest to the sun, Mercury is. Venus is the second closest. Neptune is the farthest out of the 8 famous planets. Pluto, whether you consider it a planet or not, is then farther out than Neptune most of the time, though sometimes it is closer. There are also other worlds in the solar system that some consider to be planets and others do not, to the point where there could be about 600 planets orbiting our sun.
When you say that Neptune and Pluto are the farthest out planets in our galaxy, you mean in our solar system. As I said before, though, there are other planet-like bodies orbiting the sun even father out than those. These days we've even seen planets around other stars.
6:57 theres so much space out there in space between everything you could travel in a straight line from one edge of the observable universe to the other and NOT run into anything at all. Space is that spacious
The Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and I still think of it as a planet, Pluto. When I took Astronomy in college and Pluto was still considered a planet the simple phrase was "My Very Educated Mother Just Served Us Nine Pies. "
The kind of mind numbing size that makes you realise that the human species may come and go from the universe, but no other alien life would never know we ever existed, and millions of other alien civilisations may do the same. VERY humbling!
6:25 When you're talking about us being the only planet we know of that has life, Arthur C Clarke (the author of 2001: A Space Odyssey) said it best: "Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying."
Fun fact the first flag put on the moon was made here down the street from me in Rhodhiss NC 1969 always thought that was awesome
The way I look at it is there can never be a wall in the universe because there’s always something on the other side it can never end. That blows my mind.
Carl Sagan was a god! The intro music to his terrific show "cosmos" gives me goosebumps
I think the writer Douglas Adams summed it up in 'The Hitchhikers Guide to the Galaxy':
“Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
Listen; when you're thinking big, think bigger than the biggest thing ever and then some. Much bigger than that in fact, really amazingly immense, a totally stunning size, real 'wow, that's big', time. It's just so big that by comparison, bigness itself looks really titchy. Gigantic multiplied by colossal multiplied by staggeringly huge is the sort of concept we're trying to get across here..”
NGC is an identifier for each galaxy. It is the New General Catalog. Basically, a long time ago, an astronomical was observing space and jotted down what object is where in the sky and cataloged that object. So, for example, the NGC 6744 would be the 6744th object I. The catalog of all the observed objects in space.
Actually guys AU is the distance between the earth to the sun, she was right the first time. Also Pluto is the furthest planet then Neptune and Uranus are closer to the sun than Pluto.
Planets in order from closest to furthest from the sun:
The Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
They use the Hubble and now James We b telescope to determine this stuff, as well as other instruments and technology. But primarily the telescopes.
It is pretty crazy. I feel as humans, we would never be able to travel such distance, by simply only traveling at the speed of light. I think the only way for humans to travel, would be to figure out how to manipulate space instead. Oh, how they measure distances and stuff in space is by this:
Radar - measuring distances in our solar system.
Parallax - measuring distances to nearby stars.
Cepheids - measuring distances in our Galaxy and to nearby galaxies.
Supernovae - measuring distances to other galaxies.
Redshift and Hubble's Law - measuring distances to objects far, far away.
The Voyager spacecrafts were both launched in 1977, one in August and one in September. (The September one got to Jupiter first!)
They were launched at that time because the planets would line up perfectly by the time each spacecraft reached important locations like the gas giant planets.
Each planet provided a gravity boost to fling the spacecraft towards the future location of the next planet.
Voyager 1 visited Jupiter and Saturn. Voyager 2 also visited these two planets but also went on to fly by Uranus (pronounced “your ahn us” with the accent on the first syllable) and Neptune. It is so far the only spacecraft to visit the outer two gas giants.
45 years later, the Voyager spacecrafts are approaching the true boundary where our solar system ends and interstellar space begins.
The Pale Blue Dot photo was taken in 1990, only 13 years after launch and 10 years after its flyby of Saturn.
By contrast, Voyager 2 flew by beautiful blue Neptune in 1989. So, the Pale Blue Dot photo was taken in space past the orbit of our 8th planet, but still inside the orbit of Pluto.
If I remember correctly, both the Voyager probes carry a gold disk with information about Earth and depictions of Humanity on it. Of course, by the time any other intelligent, space faring species finds it, we will likely be extinct.
cool
(in frustration) "We're never gonna get out of here." Asia, you rock.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto (no longer considered a planet though)... Order of the planets from the sun outward. ♥️
