“If we’re the only ones, it’s an awful waste of space” - J Foster, Contact.
"Either we are alone or not, either thought is frightening."- A, Cooke
It was actually Carl Sagan who said it originally. The film Contact was based on his theory.
@@dougyates7218 i dont find either thought even the slightest bit frightening
@@jimmybrice6360 Good for you.
Raymond Palmer Very fanciful, would make an interesting SF movie but is a rubbish hypothesis.
What a great presentation. We need more teachers like you!
I teach this too. Am an Electronics Engineer
He's giving you only the good news, so he's coloring the truth with his wishful thinking.
He is indeed a great teacher
With the way we treat our fellow Earth species, no wonder intelligent life won't contact us. They may just be peaceful, unlike us.
Remember the old joke,"See ya later...not if I see you first". You can believe with confidence that the advanced people found us way before we thought to even think about it.
Ok boomer
Paul R zzzzzz....I remember when that was funny.
Steffen Langeland ...lm sure they would see us as a virus, something that would need to be contained.
Amen. Gotta become a people of love instead of a people of fear first.
Thank you Chris Crowe for talking about this fascinating subject ❤️
Watching and learning from Ontario, Canada ... WE ARE NOT ALONE !!
I had an Electronics Professor in school that stated: electricity does NOT in fact, follow the path of least resistance.
It DOES follow EVERY path available!
I believe life, in the cosmos, does the same thing. Everywhere we look on planet Earth, we find some form of life, whether it is niche-like or truly abundant... it's Everywhere!
And we're going to also find at least, several other forms of life, based on other elements...
don lang what a great analogy. I would love to see a non carbon based life form. I wonder what forms they would take!?!?
It's not uniquely my thought! I base it on years of scientists and book authors' thoughts, pick out over years of reading, hearing things.
Carl Sagan, Issac Azimov, Robt. Heinlien, Ray Bradbury, Ben Bova, Dr. Robt. L. Foreward, Arthur C. Clark, many more... maybe right, maybe wrong. Who knows, until we start getting out into at least a little piece of our cosmic backyard?
Like SILICON.
let's be honest here..Aliens fly by Earth and lock their doors.
@aboctok they stop at a red star...and suddenly the mom and dad look at each other and hit the lock button.
Hilarious!
LMAO
We’re in the hood
YOU should give a TED Talk.
Well, we do know theres alot of unintelligent life here on earth
Unfortunately I thought those people were only the few. But now, especially during this pandemic, I agree with you wholeheartedly
You prob assume you're not one of them 😂
Yep. Leftys.
@@TheGreatAlan75 I guarantee I am not😉
You got that bloody right mate'
its crazy to think theres not other life when you realize what this guy is saying, its actually absurd to think we are the only ones.
Life so so so complex like ours is an exception, not a rule
@@sandipanbera and the Universe is SO huge, as in even bigger than our complex life.
@@davidca96 at many stages over the history of Earth, certain things had to go absolutely right and only then we have evolved to be so powerful. I have no doubt that life had started in cellular form in millions of planets. But I have serious doubts whether anyone else reached our level
@@sandipanbera well said, Chris is talking just for numbers of planet that are in that "habitable" zone, which is ofc huge, but then when you think about it, and start to add other things in equation, that number is not that great.
How many of those planets have water? How many of those have all those thing to life even start as simplest cell? Prob not that many.
And then on those where life started in form of cell, lets say as you said million, or even 10 millions, how many of those have all those things needed for that cell to survive and evolved thru billion years to become intelligent? If dinosaurus where not hit by asteroid, which was just perfect size to kill them, but not the other species, if that asteroid was jus a bit bigger we wouldn't be here, aswell if he was a bit smaller, dinos would survive and would still walk the earth. What coincidence is that?
And theres hundreds of things like that, which occurred just perfect for us so we are here where we are..
Let me shortened, we are alone as intelligent species..
@@tr1x243 yes I am afraid so
wish i had a teacher like that at school
Then I suggest you look to Sir George King who had 43 years of well documented contact with our neighbours from other planets of this system. See The Aetherius Society.
trust me you don't he is my comp sci teacher he sucks poo
Right!
Extremely nervous
PARK you what?
My favourite bumper sticker.
“Beam me up Scotty, there’s no intelligent life down here”.
I laughed at that because it seems so. But we are being created by super intelligent energy and light creatures called our souls. So we are brilliant holograms proven by how fast atoms vibrate and spin. Its just that the oligarchy doesn't want us to know. I had a NDE as a child, so I know what it feels like to have "aliens" around to talk to me. I felt them. Now I tell others that we are aliens, too.
100% Conscious Eternal Light Hologram: You had an NDE and did not see god or Jesus? I have only heard one other person say that when they had an NDE they saw aliens. Very interesting.
@@anonymousjohnson976
I didn't write that I saw aliens. I probably wrote that all of us are ONE energy and ONE mind, so no matter what I think I see I will know I am ONE with them.
"Extraterestial life is more certain than death and taxes"
Until ETs begin to kill us and tax us, they are certainly NOT more certain.
@@jelink22 What about meeting us? Having a drink with us?
*Being friends* with us?
Eh?
Ever thought of that one?
That is just very bad statistics. A statement of faith, not science. I have evidence for both death and taxes. The evidence for extraterestial life is very thin on the gound. So it's obviously not as certain. Sorry to spoil the dream with simple logic.
Habitable range, always measuring to human needs. There's life in the darkness of our deepest oceans, around underwater volcanoes. Lizards and creatures that live in the hottest deserts. And life in bellow freezing temperatures in the Arctic and Antarctica.
I couldnt agree more with you. I understand the perspective of where scientists are coming from, the best example they have is looking for water and Earth like conditions because that's the only known conditions for life they have. But it just seems so narrow minded. I know it's a question of resources and they have to aim at what is more likely, but for all we know there could be methane breathing, silicon-based beings with metalloid skeletons that can only survive at extremely hot temperatures. We aren't going to find them in an 80 degree water pond somewhere in Alpha Centauri.
The point you should take from this is that even when we narrow the search down to "human needs", the potential is astronomical, so if there is different forms of life with completely different environmental needs, then the chance that they exist only increases. So even with this "narrow minded" approach, the possibility of e.t life existing is still beyond huge.
He mentioned this.
Jack Exactly. Also, the more specific concern isn’t just about life, it’s about human-level intelligence, not some alien bacteria in Planet Volcano.
They could be made of gases or whatever. We apply our rules to them but i imagine they dont play by our dame rules...
The universe is teaming with life.
teeming
Definitely
@@dalea1691 not likely. Darwinian Evolution has been soundly falsified. If life cannot evolve here, then there is zero scientific rationale to believe it evolved elsewhere. There are no aliens. Fallen angels however...
@@lukehelpmetakethisdangmaskoff WHAT? To think that life can't be anywhere else, out if trillions of stars. Is not normal. Lay off the bible for a while.
@@dalea1691 WHAT?! Abiogenesis is absurd and intellectually offensive. On what possible grounds could you possibly believe in life on other planets? Perhaps you should lay off mythology and read a Bible. Seriously.
It is insane how knowledgeable and prepared this presentation is. I can tell he rehersed this. Beautiful
I believe that as continents are separated by vast oceans, also the vast outer space separate planet civilizations.
'As above, so below!'
Bit like me and as a child I realised the universe is a collection of millions of galaxies and there are many other universes, because we are limited for many of us it is hard to grasp that Space goes on forever and forever, there is no ending or edge, if there was then what is beyond that. we live on a 3rd dimensional world which does really limit us. Our galaxy alone is filled with millions of stars and billions of planets including all the other matter and gases.
Always thought same thing. Someone once told me space had to end. I said what ends it. He’s like a wall or something. I was like well what’s on the other side of that wall. Duh…
My take on this subject is this: we do know there is intelligent life (relatively speaking) here on earth. We do know that we reside in a galaxy we call the Milky Way. So, what we do know as FACT is that there exists at least ONE form of intelligent life in ONE galaxy. If we extrapolate this simple assumption to each of the countless galaxies in the cosmos, that there is at least one form of intelligent life in each galaxy, then by default there must be a significant number of intelligent life forms in the cosmos as a whole. This is a bare minimum number. As we gradually, in time, unlock the secrets of universe, we will find each other.
We won't find each other until our vibration equals their's. Until our cosmic intelligence equals theirs. The speed of light of intelligence we are a long way from.
Intelligent life would likely be interested in pretty much everything including other life intelligent or otherwise. Most likely this would start off by a visual/ radio telescope search and progress to AI probes sent out in vast numbers to candidate regions of space as they would require minimal resources and have indefinite mission duration tolerance. No aliens are likely going to go flying the galaxy to conquer others as that would be a resource heavy task with little reward and they aren't going to be trying to take our water/ air etc. as there is by far enough water ice out in space much easier to capture. So if we travel to other life bearing planets the life will probably be very simple at best and any intelligent life we might very occasionally encounter that either visits us or is space bound would most probably be some sort of robot of at least the complexity of the Voyagers we sent out but more likely far more advanced. I think we will only meet intelligent biological life if either we or they develop FTL travel.
@@steeveedee8478 The thought that we will travel to other stars even at half the speed of light is unthinkable and unachievable. In the great distant future, I suspect interstellar travel will most likely will be from inter dimensional hops or jumps or the bending of space time as a way to travers the vastness of space.
If we assume that the universe is a hamster then there must be countless other assumptions we could make one of them being that you should watch more history channel
Just because there's a possibility of life elsewhere, that doesn't mean there is just because we want to believe the odds favor it. If the universe is expanding that means its expanding IN something.(like blowing up a balloon expands it inside the air around it.) What's around the universe would, I'm thinking, be another or other dimensions so I'm more leaning to life coming from dimensions. It will not be just like us and may be not very nice!
Throughout our history, we always thought we were special. The Universe revolves around the Earth, then the Sun revolves around the Earth, etc. Why continue to think we’re special or unique in this Universe ?
The Nimitz encounter in 2004. Navy fessed up, it happened, physics got turned on its head.
Really? Physics got turned on its head? GFOH
@@Costa_Conn I have to be honest I’m very skeptical about the Navy UFO videos. I watched a great debunking video by Mick West and thought it was explained nicely. However when I hear eyewitness accounts from experienced Navy Top Gun pilots it really makes me wonder. They definitely saw something out there.
@@Costa_Conn Physics as we know it! Try explaining the workings of something mundane as a flat screen tv to a New Guinea native from the jungle.....they would be convinced it was magic.....we know it isn't.....but it is based on physics that they are no chance of understanding, or believing....get it?
@@iverstim he addressed the videos but not Fravor and the other pilot (sorry I forget her name) who were literally face to face with this object and watched it rise from the water and speed away. He also ignored all the radar data. Now there's not much he can do to examine those but I wouldn't say he debunked anything with Fraviors encounter. They actually don't know if the video associated with his encounter is actually the same object.
Great Talk Chris. Simple and easy to understand.👍🏻
We are glad you found us
An intriguing, mind bending discussion! Science is so cool!
RD; I'v been watching the night sky for over half a century , haven't seen a thing ! but a half a century is just a blink-of-an-eye when it comes to time-space ! Mr. Crowe makes a great mentor for the subject !
Out there? They are already here, flying around in big metal tic-tacs!
WTF? Why are there questions still like this? The top brass and engineers working in our military already stated clearly they can't explain the submerged object and the airborne object that made our fastest fighter aircraft look like they were standing still.
@@mandomtn1962 yeah about a 20,000 ft. decent in a second.
@@bryanguilford5807 I feel like this slow leak, the media and arts exposure are all getting us ready for the big news one day. I mean if the admission from the Dept of Navy is just a peak behind the curtain then what else is back there? Roswell? Maybe so. Contact?
Ive seen one of those flying tic-tacs up close ...well from a mile or two away and with two other witnesses. possibly about 50 - 60 feet across and the classic silver job. About the only thing we could say about it that it wasn't built by Airbus or Boeing. So the question of "are there aliens lurking about the joint" has been answered at least for us three who saw the crazy silver tic-tac doing its thing.
@@theadoresmith2777 Interesting. Was it erratic in its flight pattern? We saw something here in s.Florida, was a large (I mean it must have been huge) wash light blinking erratically and then two planes in formation looking like they were coming from Mc Dill AFB flew right at it and of course it disappeared. Then two weeks later I was stretching on the ground after a fun looking up at Andromeda and saw a bizarre delta shape with steady lights at all three points float above us at about what seemed like 8K feet then just disappear. Can't say what either was, but I have been a paratrooper and been around all kinds of aircraft and never seen anything like these two instances.

What i find so interesting is on top of all the perfect conditions that have to come into play for the earth to support life is how simple cells came into being from the basic elements in the universe and on the earth itself. Let alone group together to form the different species that exist today. So awesome.
Stephen Lane I agree when you think about what it probably takes for life to develop then go undisturbed for long enough for the life to become intelligent and self aware it’s quite a rare thing nonetheless there’s certainly some other life out there and probably intelligent as well just because of the sheer numbers
Mind blowing 4 sure!!
Well when we die on earth , we are then able to travel at light speed, our soul, spirit, or the electric charge that makes us alive. Just because you don't see it doesn't mean it's not there. We are limited in human form. Just my opinion.
Valid point
Alot of scientists believe this, and they also believe that reincarnation/consciousness being transferred to a new body. argue against it all you want but no one truly knows. imo the universe is too weird and amazing for life to just be a simple concept of life then death.
The Egyptians and many cultures believe in this also even though most in the the past have brought this up people don't learn from history only what they see now
And just your opinion.
There is no afterlife. Matter is all there is. Consciousness is not energy.
It’s our lack of appreciation for the miracle we call home, and this might be our shortcoming that gives birth to the idea the many earths have likely been repeated across the universe. However, what if the expanse of the universe is simply a measure of how great our world is, and for our world to come about, it required the perfection and stability that only an infinite universe could provide. I think we lack imagination and understanding - we are like fools taking for granted the miracles around us as mere chance. No doubt we’d treat this place with more respect if we understood the gift we’ve been given.
Not surprisingly, so far, science has proven we’re alone.
Chance. It's all it is. And we don't lack imagination. That's why so many people believe so many different things without any science evidence ...and many times, in spite of the science.
And still, it deserves all our respect for how wonderful and precious all of this is.
@UCPbFzCpWpigj26C2ppsIS3w True. Considering space and time. Distances are way too big for us to travel anywhere. Even to scan the universe, the speed of light is just too slow.
But not knowing, is not reason to believe there aren't any. After all, our planet is kind of average. Our sun is also an average star. Our carbon based life is just made of the most common elements in the universe...
Mik S - stop and smell a rose, and consider, you need to first create the universe before you can experience that simple miracle.
I think you prove my original point. The idea of thinking of our sun as average is limiting - our sun is built perfectly for purpose. If it was only slightly larger, or smaller, or closer, or further away, we wouldn’t exist.
@@JMichael2x2 Yes. Not being a "creation" and "miracle" kind of person, doesn't prevent me to enjoy and admire what we have. :)
Mik S - that’s great
There's life out there but will never be seen as the distances are to vast.

Anyone ever watch that movie, Final Countdown, where the aircraft carrier from 1980 travels back in time to 1941, and could single-handedly win WW II by itself? That's what a 40-year gap in technology can do. Now imagine an alien race from one of these planets that is just 4-Million years ahead of us! We are insects to these races. Not even stone-age level compared to them. That's why they don't talk to us.
It's my opinion that, if such a race exists, not advertising our existence would be a good thing. Considering how rare intelligent life is, logic would dictate that they destroy us before we have the opportunity to become a threat. Any creatures capable of acknowledging our existence would acknowledge that fact, especially if they've had the opportunity to observe our warlike nature.
@@donmiller2908 To such an advanced race, they would have no need to destroy us no matter how bad we get as we will never amount to any trace of a threat to them. They could probably annihilate all of humanity in a few seconds if they wanted to.

@@donmiller2908 Our warlike nature? You postulate an alien species that (would/should?) destroy our species because... we might someday become a threat ... and it's humans that would be warlike in nature??

Imagine a star system with multiple habitable planets
I hope the life forms on other planets are more Humane than our history shows we have been.
Who says life forms have to be associated with planets? Star Trek writers tried to break free of planet-based life.
Loved this
Don’t know why so many people believe in religion, but can’t fathom that there can be life on other planets just like there is on Earth. The joke is that humans now want to go to Mars, so they can destroy that planet too.
Mars is already destroyed. No magnetic field, thin atmosphere, high temperature and so on.
Ekansh Gupta Duh 🙄 I’m not talking about the atmosphere, I’m talking about everything else!
Yeah Mars is an already irradiated frozen wasteland. We may as well put it too use to help us stop destroying the Earth which IS worth protecting.
@@jedaaa so mars is like a big landfill or dustbin to us🤣
I’m not talking about the atmosphere! I’m talking about society, lives, etc, etc!!
That 10% doesn’t take into account whether it has a rotating molten core that allows the planet to create an atmosphere and em field
to protect itself from harmful rays or if the gravity is too high or too low, these things will reduce the viability of life. Even at 1%, the chances of life are high.
Earth like planets are probably much lower than 1% and that’s still a lot
There is a big difference between life and intelligent life. Remember, life has existed on Earth for hundreds of millions of years, but only recently, geologically speaking, has there been intelligent life. I've read that a large meteor impacted the Earth and caused the extinction of the dinosaurs allowing mammals, particularly primates, to evolve intelligence. If that event had not occurred the Earth might still be ruled by reptiles making me believe intelligent life is exceedingly rare.
He mentioned a lot of that!
I would like to see into the future and have a look at earth 10,000 years from now. It is going to be very a diffrent world.
I would rather look into past.
Wonderful talk. Thank you Chris.
Great presentation!
At this point, everyone can have their own planets... awesome presentation!
PLANETS!?! NAW!! At this point everyone throughout all history gets their own Galaxy Cluster! And, whether by creation or evolution, I think we're _ALONE._ (Not including life in or from other dimensions.)
Michael JC ain’t coming dude.
@@Michael-ee6tl well if evolution is true then there is almost absolute certainty that there is a life in there somewhere
@@jindrichsander9555 Some phrases I use may be harsh. No insult is intended.
Even with 14 billion years, there's still not enough time to justify life originating from rocks. Somebody has to be first. Who's to say it's not us? I know you think it's unimaginable to look at Hubble Deep Field and think, "We're first" but if we are not the first planet with life, then some other planet was. How difficult would it be for _them_ to acknowledge that _they_ were the first life in the universe? And please notice the phrase, "almost absolute certainty". Is that technically an oxymoron? And almost absolute certainty based on what? Would it be your inability to imagine that our planet could be first to "evolve" life due to the absolute shocking numbers of planets and the sheer size of the universe? I believe there is not enough evidence to _assume_ that life exists elsewhere in the time-space universe. But I can see your faith. You have more faith in rocks and random chance than I do.
Let's say you're wondering along through the forest and run across a garden with rows of plants in line and a border to help keep out critters. Do you suppose that garden just _evolved randomly?_ How many gardens would you expect to see evolving in the universe?
Again, I mean you no insult. And please go easy on me. With the brain damage I've endured, I shouldn't even be alive. I may unintentionally segue from one subject to another without noticing.
@@Michael-ee6tl but you assume that things have to happen one after another but that is not always the case, when you look at it your organs when you were in your moms belly were (with enough nutrition) evolving all at the same time, its not that the brain was first and heart or feet were last if you take away an important organ out of someone you realize the whole of human body is dependent on itself everything has to be there for it to work properly and so it had to happen all at once, life didnt wait for us to evolve first, life is evolving always, constantly and so we have no idea if there are aliens we have no visible proof of them but if we think how big the universe is and how far exactly we can grasp now its no secret that life has a big possibillity to be there and us and them being (roughly) the same technological level and being so far from each other that our radio waves cant reach the other.

'Let's hope that there's intelligent life somewhere out in Space, 'coz there's bugger all of it down here on Earth' - M Python
I'M BRIAN AND SO IS MY ALIEN !
Amazing!! If the conditions for life have to be the same i.e water and sunlight within the "habitable zone" is it safe to assume that its likely that life and evolution have taken similar courses and alien life maybe very similar to ours. So perhaps other beings close to or the same as "humans" are at various stages of evolution right now? 👽🌎
with such a vast universe, and so many planets. the chances of life evolving on a similar path to ours has to have been met time after time. we came from somewhere, the asteroids meteors and space dust filtering into our atmosphere carried small pieces of organic materials, combined over the millions of years, they eventually started life. This must have happened elsewhere too, to think otherwise is just crazy.
I totally agree. Why cant we hear them. They have to be giving off detectable signals(maybe not intentionally) that we should able to hear. I dont know, Im asking.
If we can listen for a few more millions of years, the chances will improve a lot. We're listening just for the past 30 years or so.
And we've to consider the universe is really big. It's easy to miss where to look for.
And we're also very limited by the speed of light.
100 light years is nothing in terms of distance in our own galaxy - let alone the rest of the universe.
So, even if some other civilization also starts to emit some signals, we will have to wait many more years to give time for the signal to arrive.
Having many more civilizations out there doesn't mean we will ever be able to communicate in our civilization life time.
@@miks564 I believe it's because intelligent life is extremely rare. The universe is far too violent to support intelligent life. We could very well be alone.
Alabama Mothman
I agree it will be extremely rare. But then again, Extremely rare is not enough in the whole universe context.
If there’s a slight chance for something to happen, then it will surely happen somewhere give or take some million years. ...and we’ve a couple hundred billions of galaxies available for it to happen in one of its own several hundred billion stars.
We’re a living proof of that.
I think it's more probable that not only are there other beings out there but they put us here. An experiment of sorts with the dinosaurs being a failed design. Just a thought
Quite a design leap.
I think we may have been placed here as an experiment. However I don't think the dinosaur was a failed experiment. They were doing fine but happened to be in the path of an asteroid.

@@beatarmy2570 I don't know. I'm still trying to figure out exactly what seeded us?
Are we a hybrid?
How long ago?
What was the purpose?
@@jackderipper2233 I think the Bible and other religious texts detail the "gods"/aliens quit well. If you take what is said literally.
i am so sick of everyone trying to calculate “earth like conditions” to justify if there is life elsewhere. sorry to burst their scientific bubble but life as we know it here on earth is not the only type of life in this infinite universe. not every species needs the exact conditions we need to survive. that’s the arrogant mindset of humans at work again
The problem, though, is that if there is life that is not carbon-based, would we even detect it? Would we be able to see it if it was right in front of our noses? There’s actually a fringe field of science where they’re trying to detect alien life... HERE, on Earth. We’re not talking about Star Trek aliens that walk and talk but might breathe different gases. It could be an unusual rock formation that communicate in such a foreign way that we don’t even know it’s there. So my point is, it’s not about arrogance or bias, we’re looking for life “as we know it” because it’s probably the only sort of life we can find. It may be pointless to try to look for life that’s so alien to us that we won’t even see even if we look directly at it. That’s a waste of time.
@@artman2oo3 that's a really interesting way of thinking about it
Miranda people who can see things that nobody else can see, are genius! A lot of them are just nuts though!
@artman
that was my exact point
JohnnyBlaze5680 Agreed.
Interesting idea
Brilliant, thanks
Nice presentation. Enjoyed very much.
Yes there is life outside of the earth!
Probably, maybe not.
wow that number with the sand is mind blowing!
Great teacher 👏👏
Just arrived from Jaxtuxia V. They had an interplanetary war with the Goghroians and both planets were destroyed.
May they rest in peace. :'(
They’re not only out there. They made us.
Never-ending party not quite
I agree... And they are watching us... Closely. It would boggle our minds if we only knew. Maybe theres a ultimate purpose to our being. And one day it will be revealed to us.
aboctok there is a mountain of evidence. If you are too lazy to find it, I can’t help you.
aboctok I’m not going to hold your hand and lead you to the evidence, objective and subjective. I haven’t got time for that. Believe what you will. Have a great day.
aboctok oh I could “lead” you to lots of evidence. However I don’t feel inclined to. Particularly when it comes to small minded arrogant fools who think they are smarter than others. The multiverse is a far stranger place that your little 5 senses tell you my friend. Crack that little mind open a mite and you just might begin to gain some subjective evidence of what I speak of for yourself. As for the objective evidence. Well do your own homework as I have for 31 years. I’m not going to hand it to you on a plate, not with that attitude.
not to mention the way they formulate answers as viewed through the telescope forces a ton of guess work.
Incredible!
It's very simple ,if life is here it's out there how do you think we got here
God created us here! Did he do it elsewhere? Without God there would be less then blackness of space. There would be no space or blackness because blackness is something, and there is nothing without God.
@@johnwriterpoet1783 what god are you referring to
John A your worldview and beliefs are very limited as they do not conform to the modern science. There are endless other galaxies and planets you can find proof of it quite easily. Why would “God” make all those planets and universes and then not even mention them in his precious little book? Please don’t tell me you believe in Christianity, a religion of misunderstood texts that aren’t even the original translations. Why are we humans, a speck, less than a grain of sand in the grand scheme of things so special? We probably aren’t, unless you believe it’s all some sort of conspiracy in which large numbers of the scientific community are lying and misleading the masses with new scientific findings about space, the Earth, and the origin of our species.
@@johnwriterpoet1783 ha ha ha...good grief!...eventually everyone will realise there is no such thing as God...thankfully, and the world will be a better place
@@steveedwards3217 I'm going to believe in something bigger than me because I'm not all that and whatever energy and life I'm filled with came from somewhere and it most likey will go somewhere and that's better than being nobody from nowhere that will cease to exist. takes too much meaning out of life to live in that reality. alot of good can be done in a lifetime if you don't live only for your personal self interests at all times
Can you imagine them landing and they say, “ Take me to your leader?” 😂
I will take them to my gf's father
and "sorry we stomped all over your crops"
Awesomeness ❤️
Great show! Get ready, as Disclosure is near.
To anyone with a sense of science AND life, it's pretty clear the number of planets with life out there, will be something like the number of grains of sand in the whole World
But instead of science spending so much time looking for Aliens, how about for now we focus just little bit more in preserving life in this one?
If any of the species we've led to extinction was Alien, the entire World would be outraged, but because they're the next door neighbors, most are Ok with it😤
Human imagination is the psychic connection to the realities of an infinite multiverse.
When I was comatose I traveled here from another dimension. So, you are correct.
RU Foreal and also the speed of thought is faster than the speed of light...
It's not the water, it's the carbon. At our temperature range, it's carbon and water.
At every temperature range, different forms of carbon are stable and interactive. They would rely on different liquids to facilitate chemical interactions. Maybe liquids that didn't expand when frozen might more easily facilitate complex carbons?
Good video !
they already know about us
I just watched another distinguished lecture on why we may be all alone. Go figure. I figure I have the answer fairly well narrowed down to two possibilities; yes or no.
I think the Fermi paradox is an explanation for why it's not as easy as we might think, but not much more than that. It's a thought experiment and the only supporting evidence for it is "I don't see anything" - with little emphasis on the fact that space-observations have been a very recent advance.
I'm particularly interested in the investigation of potential life under the sub-surface oceans on Jovian and Saturnian moons like Enceladus and Europa - which seem to share many geologic characteristics with one of the likely sources of life on earth. Its hard to get there and getting a submarine there, yet alone one rated for space and a 65km deep ocean (which is about 5 times deeper than our deepest ocean trenches) to check out potential volcanic and possible chemosynthetic life. That's in this solar system.
If we found evidence of life elsewhere in the solar system, even if it were just a fossilised virus deep in the Martian crust, wouldn't that change it?
The question boils down into - how often does life form and how often does life go out and how often does life get intelligent enough to survive, thrive or do something that we've merely not thought of as of yet. Evidence is increasing that there are more planets than we thought and if we get evidence that life can form multiple times in a given system, then you can appriciate that the odds have indeed increased - but there's always the potential that intelligence can't sustain itself. But that's just a possibility. Don't forget the universe may be 14 billion years old, but the last stars go out in 100 trillion years time. There's still a lot of time for other intelligent species to grow even from scratch - we could well be the first. We just don't have the answer just yet. But that's it, just yet.
There are 3.67 million civilizations just in our galaxy. More than 15 races have visited Earth. Billy Meier is still in contact to this day. They are giving is information about the vi rus.
@@onewhostudies6856 interesting... But I don't think there's much evidence for that... Consider we've known about viruses for around a century by now and corona viruses are a family including SARS and MERS which were previous pandemics that had higher death rates but lower infectivity (so got a lot of attention and were quashed down, a bit like ebola).
It's just that while Covid-19 does have some unique things about it, it's not the sort of thing we should need alien help with... Sorting our plastic pollution issue or our lack of carbon management would be far more helpful.
While driving between two farm communities i passed a metallic cylinder object about the size of a mobile home on the ground in a field along a tree line. 20 to 30 minutes later, passing back thru same area object was gone. I know enough about moving heavy equipment to know it would be impossible for cranes to be brought in, set up to lift object, position a flat bed truck to load object on, secure the object with chains and straps to the flatbed, with all personal and vehicles leave the area in 30 minutes or less
At what site can we find the data?
Why do humans believe they are the supreme physical life form and life has to be like us?
We're inately spiritual beings; designed for life on this Earth. That's the answer.
Do you?
We dont know... We just search for life like us because we dont know any other kind
Because a lot of people are credulous and have huge egos, thus, they believe in ancient fairytales that claim an invisible man in the sky made the universe just for them because they’re “special” 🤦♂️🤣
AussieNaturalist Not for us ding bat but for himself. He didn’t have to create anything but since he did you exist.
I'm sure that there are thousands of planets out there with life on them. Ocean worlds filled with something like fish, planets with endless plains with grasslike plants, jungle worlds with amazing varieties of animals...but worlds with intelligent life which ALSO developed space travel? That's a steep ask!
The vastness of space is too much for there not to be though.
Thousands is a huge understatement.
Just inside the galaxy are TENS of BILLIONS of habitable zone planets with water.
If life is on 0.1% of them, that's TENS of MILLIONS with life.
If just 0.1% have advanced lifeforms, that's tens of thousands with civilizations.
If just 0.1% have interstellar civilizations, that's at least ten civilizations capable of traveling here.
That was using 0.1% chances as a super conservative estimate.
He said about analyzing data
How can we learn and find that
where did the first live come from ?
To say that their is no intelligent life elsewhere in the universe is like being a fish in a pond and saying to the other fish that this is the only fish pond in the world
1:46 crickets 😂🤣
He better not give up his day job 😂😂😂
On one end of the spectrum, you have the vast number of potential planets mentioned here. On the other end of the spectrum, you have all of the incredibly freak occurrences outlined by the "Rare Earth Hypothesis." While I certainly think Chris is right about the potential for simple life to be out there, perhaps even abundant, the real questions arise with complex life. For instance, if you "do the math" solving for all of the astronomically rare 'chance occurrences' that needed to happen - essentially perfectly - for single cells to make the jump to complex organisms on this planet, your number might just be comparable to that potential number of planets out there... which, unfortunately, makes it very difficult to determine whether or not we're the only lifeform cool enough to contemplate our own existence.
PsyintZ
You shouldn’t assume that life out there will be just the same., needing the same type of planet and same type of star. But even assuming that, life basically happen on this planet as soon as it was bearable ready to sustained it. And it took even less time (in terms of our planet age) to evolve into intelligent life.
Freak occurrences are frequent if we give them billions of galaxies and billions of years.
Where can I get all this data?
10 thousand billion billion quadrabadollion, + 6 milliom badollion shabadadoolion stars. For you to imagine this take a box of sand and then multiply that box of sand by 6 milliom badollion shabadadolion and you can imagine how big the universe is.
Meanwhile all stars and planets spinning in Evey direction at different unimaginable speeds. Yeah we know he says!
Actually our whole galaxy and all celestial bodies in it spin on the same plane and if im not mistaken in the same direction...
Incredible...
It's good there's life out there and also that is so far, you never how aggressive and vicious other aliens can be
Sabininho you’re assuming they’re at or below our level of technology. Let’s hope they are or don’t find our Voyager probes/hear our radio messages. :-D
IRememberJeep exactly, it’s quite a dilemma, right?
We are probably worse than they are
@@irememberjeepz well I was presuming they could be surpassing us in technology, but then they could be anything from pacifists to lunatic planet destroyers and then all things in between
The Moon we have gives me a great deal of doubt about life beyond microbial elsewhere. Considering how we think it formed, it was a planet sized body that collided with another and both bodies ended up with just the right mass to fall into place. That is a very unlikely event in the least, to get just the right sized moon, just the right tilt, just the right spin. I do not say this to make any claims but only to point out how much we do not know and if that much is true there most certainly is a lot more stuff we don't know we don't know. But we already know this. Moons.
what if consciousness creates everything? QT indicates this.
@@imrablakeman3467 What if, we don't know if consciousness has anything to do with anything as we have yet to even know what consciousness is or if it even is. Maybe but we are nowhere close to being able to determine such a position. I have yet to see any compelling evidence either way. Lets talk again when we confirm dark matter. lol
@@imrablakeman3467 That would be more Copenhagen interpretation which is one of a few views held. It is incorrect to say QT implies this, it is better said a certain interpretation of QT implies this and even that is hazy at best. We do not know. Not yet.
@Dennis Feenstra In terms of probabilities in a certain view not in all, I do not hold to any idea on the moons formation. I was speaking to the most common one not on its position being accurate or not. If it is a requirement that such an occurs as in the predominantly held view holds then it would be rare. This is the rare earth hypothesis in short, I am not saying I agree with it, only that it gives me doubt in regard to Fermi's.
The moon is a space station, brought here after the destruction if the planet that's now the asteroid belt, it brought the survivors to this planet, and then our civilisations started...
We live in a digital reality!
Distance and time are illusions!
I wonder where space ends and if so what's beyond it
Earth is a planet big enough to hold onto an atmosphere, but not so big we can't get off it
