Its crazy how light can travel for 13.4 billion years through space to reach our telescopes on Earth. How the hell do the photons stay together without falling apart for 13.4 billion years. I just cannot wrap my mind around it.
orangedac from the photon's point of view, the journey was instantaneous, and its source and destination were the same point. Yay for weird physics of relativity!
I hope governments keep investing in space exporation because it keeps so many people interested in math and science that without it we lose a lot of future scientist. And that would be bad in general.
That's what in worrying about. Considering the current presidential candidates, I'm very worried about space funding. It may get less money so less exploration. But I do agree that I want more space!
I have a feeling spce isn't going to get much more attention or funding than it currently is for at least a few more decades untill some sort of change in government about hte opinion of space exploration and what it can do for us.
I believe that with the James Webb Telescope lots of theories about the Universe will come into question . The first theory to come into question may be the age of the Universe itself . I for one believe it to be far older and larger than currently theorized . But we shall see .
I wish I was born 500 years in the future from now, the things we would know, the places we would have visited, wow! Well, atleast we are the starting generations for the great things to come!
going on about this though, imagine if we sometime find a very far mirror-like space object/planet. if we look at it from earth, we would see very early into our solar system (disregarding the convex-light bounce effect that would flip everything upside down), right?
The voice comment of this video contains several mistakes. Early galaxies had a different chemical composition (much more hydrogen) than ours. Their stars were also much bigger, their lifetime was shorter, and they had no planets. Our planet exists because the sun is a third generation star, made from the ashes of former, disappeared stars. Furthermore, those early distant galaxies very likely had *not* the spiral shape that you find with space Engine. Space Engine is a magnificent simulation program but is not always as accurate as you would expect.
considering those stars had very very short life spans i’m assuming by that there already could’ve have been some second generation stars at that point which obviously doesn’t really help for life due to the sheer amount of complex molecules but planets could have formed by that point especially gas giants
Too good. Love that zoom out and zoom in details starting from the earth. Love that speed indication in Gly, Mly....Thanks for sharing your knowledge ...Great video...
+Anton Petrov (WhatDaMath) You literally blew my mind when you told me you reached the end of the visible universe because it's expanding to fast for us to see. Thanks
+Anton Petrov (WhatDaMath) Thar's not the real Anton... he sounds familiar though *takes off mask 🚢 👔 👖 I KNEW IT!!! He was the Titenic the whole time!!!!!
Just to reiterate, distant galaxies beyond our visible horizon, while having their own intrinsic motion, they're are not moving away from us through space faster than light. It is the expansion of the space itself that is carrying the galaxies away faster than light can permeate through it from those regions, beyond the horizon.
Time and distance boggles my mind soooo much that i tend to believe we are living in a simulation of some sort, but thank for all the pictures of space Anton !
I tried it in spaceengine, all stars had a lowered magnitude, so I raised it to a level where at least some got visible, so around +12.0, and at that point the program crashed.
Are we ever in the same place twice? If we were able to time travel, would we be in the same spot in our galaxy, in space if even in space we are moving constantly and expanding at the same time?
Anton god I really love your videos.😍 Please keep up the good work. You are exceptionally intelligent and knowledgeable on astronomy about other galaxies and stars. I am so so so so into this as well. This is my new hobby. Within the last 3 years I have taken a very deep interest on space and the more I read the more I want to know. It’s a vicious cycle But I love it.
When we say that the Galaxies are moving away from us faster than the speed of light it raises several more questions. 1. Are all Galaxies moving away from one point in the same direction? 2. Are all Galaxies moving at the same speed? 3. If we are also moving at a certain speed then is our speed slower than those Galaxies which are moving away from us? 4. Are Galaxies moving away from each other in opposite directions which makes them move faster than the speed of light? If Galaxies are moving in opposite direction then obviously they are circling each other which implies that the space has boundaries.
you should turn up the visibility/apparent brightness of all the objects.. at this distance you can see the overall structure of the entire universe in SE its amazing there is no way there were terrestrial planets back then, it would have taken billions of years for the stars to go through all the processes required to form the heavier elements in enough quantities that could form planets
Well,probably nothing,in fact if you got past the edge(which even if you were going the speed of light you still wouldnt get past the expansion of the universe but lets just say you can in the hypothetical situation)your body may turn into hawking radiation.
I really liked that you got into the topic of colonizing space in the end of the video. I for my part definitely think that's what it's all about... Then again... Are we really ready to go to other planets when we don't even manage to get along on our own home planet? A lot needs to get sorted out before we can get that ambitious, I think...
"~400 million years after big bang, there might have been life" I don't think so, since the atomic nature of the universe back then would have consisted mostly of Hydrogen and helium, with scarce or no heavier elements needed for complex life. At least the complex life that we know.
Space/Time is fluidic, according to Einstein. Within Space/Time, the Speed of Light is a limit; however, there is nothing in Einstein's Field Equations which prohibits Space/Time itself from expanding faster than the Speed of Light.
So if that galaxy is 99% the age of the universe distant that must mean that the universe inflated to at least 13 billion light years across almost instantly right? Or the light from that old galaxy would have past the region of space that our galaxy later formed in long long ago. For example if turn a torch on for 1 minute pointed to space then turn it off a man on the moon would only ever be able to see that light for the 1 minute in was turned on after which it would have travelled out of his view for ever.
This brings up the question about how Space Engine handles time. If I go to the visible edge of the universe or beyond, will the galaxies there be as they would be in the "present" (whatever that means in this context) or in the remote past as we see whatever light makes it to us from them? Or does the software just use the same procedural formulas throughout?
Imagine, if you will, that we do find a way to travel there (worm hole technology?) and we set up very powerful telescopes around a planet much like Earth in that galaxy. Thinking about such a thing blows my mind... which isn't saying much because I'm not very bright. lol
If Space is expanding a Galaxy with a Redshift of Z=11 will have the same apparent diameter of a Galaxy with a redshift z=1.5 due to an optical illusion. I wonder is this was observed. It would be a verification of expansion of Space or a data point suggesting maybe Space is not expanding. Which one is it?
In the next video talk about Sedna. Shouldn't it be a planet because it's round; it orbits the sun; it isn't part of the Kuiper belt. I know it's hypothesised to be part of the oort cloud but we haven't found that yet...
I can't help but to think that all the super distant objects are gone(dead/destroyed). and that there were civilizations and species that may have lived /died through out the life cycle of a galaxy over billions of years. just to think of the scale of the known universe, let alone the unknown universe is just.....😵 guess that's why I love video's like this.
hello anton, can you teach the best configurations of this game? (i have a pc with all specifications except the RAM that is 6 gigabytes and my video card have only 1 gigabyte of memory)
things about this galaxy that you should consider before saying there were probably planets waaaaaay back then. 1: all of the starts back then would have been first generation stars. That means they were all mostly made of hydrogen and helium. and very little heavy metals where compared to the third generation stars that exsist today. Which means there wouldnt have been enough heavy elements to create planets. 2: all the stars back then burned bright, hot, and were short-lived. So if there were planets back then, they would have not had enough time to develop life. Also, the stars would have been 1000X more powerful than our sun, which would have cooked any worlds that might have had in deadly radiation. So, no. Life probably didn't exist back then.
It is highly unlikely that there was life back then, because there was a lack of heavy elements in that Era. It takes millions of years for the first stars to go supernova and seed the space around them with the heavier elements that you need to build terrestrial worlds.
That is where the galaxy WAS 13.8 billion years ago... now the question is, where is it NOW (13.8 billion years later?), and for that you use the Hubble Constant (based on Red Shift), to account for its gradual acceleration away from us (in the expansion of space) and, if it still exists, it would be 46.5 billion light years away now, 13.8 billion years later... But a question... many say that the furthest is the oldest, so why is it assumed that the furthest is the oldest? Why can't we have 'old' right next door? There is something funny going on with the furthest/oldest assumption... consider the opposite: that the Milky Way is the furthest galaxy that beings in that galaxy can see, and we are Red Shifted (to them), and they are assuming WE are the oldest galaxy... and indeed, it is said that the Milky Way is one of the oldest galaxies, maybe 13.6 billion years old... so 'furthest' does not equal 'oldest' (yet you see that mistake being made all the time)... Further, if we still want to see it 13.8 billion years from now, we will have to be able to see 46.5 billion light years away, by which time it will be even further, barring an expansion reversal of the universe (ending with a Big Crunch) which, if any other universe is too far to gravitationally affect anything in this universe, then this universe is guaranteed to collapse in on itself, there being only one 'universe gravity well' acting on the matter and energy (says me)...
If space does fold around on itself and there is no end could one of the very distant galaxies we see actually be our galaxy some billions of years ago?
There is no way gravity could form these fully formed galaxies at the edge of the visible universe, there is not enough time alloted. especially not with only 400 million years.
its highly unlikely there were even planets that early, it took thousands of generations of stars to produce enough heavier elements to form planets and life.
It's speculation at it's wildest. If it is beyond visible universal horizon and the universe is expanding faster than the speed of light how can you see it or speculate about it's brightness?
I wonder if the amount of stars and planets in the universe actually has a limit, like if there is currently a certain amount of matter and energy in the universe. Or if the universe itself is really infinitely large. Like, could you really just fly out in it forever? And finally, what if we go far enough beyond all the galaxies that ever were, and beyond that are entirely different states of matter and energy that we cannot yet comprehend? Or is it infinite, and just void forever at some point?
10 month old comment but I gotta say this. Let's say you had an intergalactic space ship that could go infinitely fast and is indestructible. You could go out into space until there is nothingness and you are the farthest existing thing from the starting point of the universe. There is no edge of the universe like a wall which is expanding, it's not like a game with coding boundaries, it's completely infinite and goes on forever. Try wrapping your mind around that one
Anton. So if the universe is 13.7 billion years old are we seeing the galaxy from that time or from the 32 billion ly distance. So it has moved almost 20 billion more ly from our location since then? Since we are not that old of a solar system then the light does not reach us until we develop. The light we see as of today is how old? No matter the answer then this galaxy at sometime was moving faster then the speed of light for a long time. Also if this galaxy is no longer because of its age it can not be 32 billion light years away, can it? So in 20 billion more years we will see it's light from that age or maybe beyond what we can actually see. Just how far can we see out into space? James Webb will see beyond?
Cool vid - but curious how life could have existed in a galaxy that old with no 2nd generation stars? All the complex elements are formed from supernovas so how can there have been other elements besides Hydrogen and Helium? Although now im thinking of aliens made up of only Hydrogen and Helium and its weird... :)
A fully-formed galaxy only 400 million years after the Big Bang? Doesn't that contradict the standard model? Also, looking that far back, shouldn't we see the entire universe, because it was a lot smaller then, but much more dense. So how do we see an isolated small and fully-formed galaxy so far back in time, a mere 400 hundred million years after the Big Bang?
Quantum particles pop in and out of existence at random in a vacuum. So, consider light traveling for 32 billion light years. The photons would collide with these particles at random during its journey. Each collision would absorb a small amount of energy from the photons that would over grate distance and time cause a red shift. The background microwave radiation would be caused by the quantum particles popping in and out of existence. the Idea of a big bang and the universe expanding is a neat idea; however, a big bang and universal expansion is not the only way to explain what we observe. For all we know it could be as flawed as the idea of the earth being the center of the universe, and the stars being made of milk. All red shit can tell us is that photons have lost X amount of energy. Why the photons lost energy on their voyage is a real misery that needs a more solid explanation based on more that circumstantial evidence.
everyone refers to the most distant galaxy as the oldest cause it took the light from this galaxy 14 bil. years to reach us but the light from our milky way also took 14 billion years to reach them so to them milky way is the oldest...
When I was young 1980 I took my cheap telescope and a school microscope..... then I shot a reflection onto a slide glass so I could magnify it. What I saw is Galaxies everywhere beyond the stars we see in our milky way galaxy. I'm not a scientist, but is there any differences from, for example where the galaxies were 1 year ago versus now? If there is no changes.... there is no Universe... there is just a reflection of our own galaxy. A hint to think about for you all scientists, by DVE
1 year is a very, VERY short time in the cosmological time frame. Even light takes millions of years to traverse intergalactic space. If you don't know how short of a time 1 year is and refer to childhood memories, you probably shouldn't argue with the professional scientists.
This website shows the scale of our solar system if the moon were the size of one pixel on your screen. joshworth.com/dev/pixelspace/pixelspace_solarsystem.html
I don't know what the he'll is wrong with our current home, that you Anton are looking so eagerly to leave for some another remote place in the universe.
If this galaxy emitted the light only a couple of hundred million years after the creation of the Universe we should've been very close to each other. How it happened that this light reached us after 13.4 billion years or probably we were already far far away and the Universe is much older.
Its crazy how light can travel for 13.4 billion years through space to reach our telescopes on Earth. How the hell do the photons stay together without falling apart for 13.4 billion years. I just cannot wrap my mind around it.

How crazy that we can take a look back in time in a live telescope with all these stars and galaxies. that literally is like a look back in time.

Life on other planets have come and gone I believe and will for a long time in this universe...
There goes that word "colonize" again.

I wonder what the edge of the universe looks like.
a big dark abyss of nothingness... due to objects moving faster than the speed if light.
Technically there may not be an edge.
Since there is no center.
We are the center.
But go to the andromeda galaxy and you're also in the center.
Well,probably nothing,in fact if you got past the edge(which even if you were going the speed of light you still wouldnt get past the expansion of the universe but lets just say you can in the hypothetical situation)your body may turn into hawking radiation.
Assuming you could travel faster than light, you'd eventually end up right where you started.

So, no. Life probably didn't exist back then.
Heck, even a [free] simulation accounts for the Particle Horizon.
Video is about space engine
Description: *Download universe sandbox from here*
The launch of the Webb telescope was pushed back to 2020 now. I can't wait until it gets pushed to it's limits like Hubble.
hey when i used the telescope mode in space engine it had the red shift just like how they tortured hubble to the limit
It is highly unlikely that there was life back then, because there was a lack of heavy elements in that Era. It takes millions of years for the first stars to go supernova and seed the space around them with the heavier elements that you need to build terrestrial worlds.
I really like your videos Anton. Informative and interesting..what more could you ask for :p What Da Maths deserve more audience!
Can you see all of the galaxies outside the universe with brightness at max?
hey anton, why do u sound sick? r u sick when u made dis video?
but the question is, will the telescope launching in 2018 see color?
No, that's not how red shifted light works.
That is where the galaxy WAS 13.8 billion years ago... now the question is, where is it NOW (13.8 billion years later?), and for that you use the Hubble Constant (based on Red Shift), to account for its gradual acceleration away from us (in the expansion of space) and, if it still exists, it would be 46.5 billion light years away now, 13.8 billion years later...
But a question... many say that the furthest is the oldest, so why is it assumed that the furthest is the oldest? Why can't we have 'old' right next door? There is something funny going on with the furthest/oldest assumption... consider the opposite: that the Milky Way is the furthest galaxy that beings in that galaxy can see, and we are Red Shifted (to them), and they are assuming WE are the oldest galaxy... and indeed, it is said that the Milky Way is one of the oldest galaxies, maybe 13.6 billion years old... so 'furthest' does not equal 'oldest' (yet you see that mistake being made all the time)...
Further, if we still want to see it 13.8 billion years from now, we will have to be able to see 46.5 billion light years away, by which time it will be even further, barring an expansion reversal of the universe (ending with a Big Crunch) which, if any other universe is too far to gravitationally affect anything in this universe, then this universe is guaranteed to collapse in on itself, there being only one 'universe gravity well' acting on the matter and energy (says me)...
Hi Anton Petrov which app are you using for all these animation. 🥺 Please reply.

There is no edge of the universe like a wall which is expanding, it's not like a game with coding boundaries, it's completely infinite and goes on forever. Try wrapping your mind around that one
happy Easter
when you think about it, its just strange that the universe is what it is...
all of it shouldnt even exist, but it does
Seriously dude, what kind of Software is it :3 ??
i want it
mmmh based on a mouse pointer, your OS is Mac isn't it?
that is space engine just search that in google
you can get it here en.spaceengine.org
Vikry Malik u helped me, but oh God, haha i'm using linux but the requirement is windows :3
anyway thanks in advanced
***** i hope space engine will be released on Steam :3
Anton. So if the universe is 13.7 billion years old are we seeing the galaxy from that time or from the 32 billion ly distance. So it has moved almost 20 billion more ly from our location since then? Since we are not that old of a solar system then the light does not reach us until we develop. The light we see as of today is how old? No matter the answer then this galaxy at sometime was moving faster then the speed of light for a long time. Also if this galaxy is no longer because of its age it can not be 32 billion light years away, can it? So in 20 billion more years we will see it's light from that age or maybe beyond what we can actually see. Just how far can we see out into space? James Webb will see beyond?
The launch date of the James Webb telescope is only 3 years away, and always will be.

... that aged particularly well i must say
This makes me think that the universe is much older than we estimated so far.
this is really mind blowing
This is truely facinating
When we look up at the stars we feel the same wonder that our prehistoric ancestors felt.
something else: Betelgeuse probably already supernova-ed. the light from that just has not reached us yet
Carter Adams antares too
Your videos are amazing!
Try to find a warm Gas Giant with the most habitable moons )They don't all have to have life, but one has to) :)
I love this channel
What is the radius of the known universe?
Is it greater than 35 billion light years? 😨
AntiMessiah no it's 46.5 billion light years.
It's 999999999999899999999999999999999999999999 light years
Sorry no
I mean yes
Cool vid - but curious how life could have existed in a galaxy that old with no 2nd generation stars? All the complex elements are formed from supernovas so how can there have been other elements besides Hydrogen and Helium? Although now im thinking of aliens made up of only Hydrogen and Helium and its weird... :)
thank you for all your videos i am now interested in astolology
A fully-formed galaxy only 400 million years after the Big Bang? Doesn't that contradict the standard model?
Also, looking that far back, shouldn't we see the entire universe, because it was a lot smaller then, but much more dense.
So how do we see an isolated small and fully-formed galaxy so far back in time, a mere 400 hundred million years after the Big Bang?
Quantum particles pop in and out of existence at random in a vacuum. So, consider light traveling for 32 billion light years. The photons would collide with these particles at random during its journey. Each collision would absorb a small amount of energy from the photons that would over grate distance and time cause a red shift. The background microwave radiation would be caused by the quantum particles popping in and out of existence. the Idea of a big bang and the universe expanding is a neat idea; however, a big bang and universal expansion is not the only way to explain what we observe. For all we know it could be as flawed as the idea of the earth being the center of the universe, and the stars being made of milk. All red shit can tell us is that photons have lost X amount of energy. Why the photons lost energy on their voyage is a real misery that needs a more solid explanation based on more that circumstantial evidence.
It's mainly spacetime stretching that redshifts light.
The age of the universe is getting older all the time. It is now estimated to be 13.772 billion years old, but some even think it may be older.
everyone refers to the most distant galaxy as the oldest cause it took the light from this galaxy 14 bil. years to reach us but the light from our milky way also took 14 billion years to reach them so to them milky way is the oldest...
What is name of the program that you were working in the video?
Those far away Galaxies aren't there anymore. That was like 13 billion years ago.
that
galaxy
reminds
me
of
SPORE :,)
5:24 LOL THAT STAR IS CRAZY XD
When I was young 1980 I took my cheap telescope and a school microscope..... then I shot a reflection onto a slide glass so I could magnify it. What I saw is Galaxies everywhere beyond the stars we see in our milky way galaxy. I'm not a scientist, but is there any differences from, for example where the galaxies were 1 year ago versus now? If there is no changes.... there is no Universe... there is just a reflection of our own galaxy. A hint to think about for you all scientists, by DVE
1 year is a very, VERY short time in the cosmological time frame. Even light takes millions of years to traverse intergalactic space. If you don't know how short of a time 1 year is and refer to childhood memories, you probably shouldn't argue with the professional scientists.

A long time ago in a galaxy far far away... bum bum bumbumbum bum bum
An alien was traveling in a phone box. A blue box. A, a police box. And it was bigger on the inside.
EWWWWW DOO WEE OOO

Yep.
and that galaxy belongs to me
have you ever seen an at-at walker have sex with a rancor
I don't know what the he'll is wrong with our current home, that you Anton are looking so eagerly to leave for some another remote place in the universe.
Its resources will run out and we're currently destroying it.
so the further yuh go the wider it expands.the universe
Can you make a video of the most inhospitable exoplanets
If this galaxy emitted the light only a couple of hundred million years after the creation of the Universe we should've been very close to each other. How it happened that this light reached us after 13.4 billion years or probably we were already far far away and the Universe is much older.
