'You'll never get your head around how big the universe is,' warns astronomer Pete Edwards of the University of Durham in this film about measuring astronomical distances.
'There are as many stars in the universe as there are grains of sand on the Earth.' So how far is a light year? And supposing our galaxy were the size of a grain of sand, how big would the universe be?

Mad respect to the guy who counted all the grains of sand on earth
Yeah he must be exhausted.
...that would be Leprechauns...
LMFAO! Word up!
Eh? It would be calculated using maths not by actually counting each grain, thats impossible

ROFL!
Its mind blowing how insignificant we are in the grand scheme of existence, yet we live our lives like we are the center of the universe
I’m a pretty big deal actually speak for yourself
It’s true…Jim is a huge deal
If we are the only planet created that supports life, then we are exceedingly significant beyond measure.
@@mrbanjopete that is true
If we are the only planet with life on then I would go as far to say we are the canter of the universe
The microworld is endless too. Size is relative if you REALLY think about it.
Yeah. I think we are part of a continuum that is both infinitely large and infinitely small. We can only see and describe a limited range along this continuum. And yes, everything is relative to our position in space and in time. Sorry, I can go on about this stuff ad nauseum. 🤯
@@pooryorick831 yes! Oddly, I had a dream a few nights ago where I could travel inside a solid billiard ball. Why a billiard ball, I don't know. But once at the atomic level it was mostly empty space, in fact I could duplicate the atomic structure of the ball by placing duplicates of every atom next to each other thereby creating two billiard balls with twice the density and weight, but occupying the same space. I realised this process could be repeated infinitely. Of course I could be wrong.
@@stevelayton1271 yeah you’re probably wrong
You only make things more difficult ,dude 😆
Tell my girlfriend that.
I feel sorry for any intelligent life that evolved on a planet where sand is non-existent. They haven't got a clue how big the universe is.
Tony Garratt 😂😂😂😂😂

Look up cross examined

I think any intelligent life that lived on habitable planets will have sand sort of, I mean sand is just a fine particles of stones, minerals that got grinded by ocean of liquid. As far as we aware of habitable planets needs water to be hospitable to support life

I remember my science teacher mentioning the concept of looking back into time with stars way back when I was a freshman in high school (about 15 years ago), and it was the first major thing I can remember that really made me stop and rethink life and how it works. The fact that I’m looking at something, but not seeing it as it is now, but as it was because of distance is absolutely baffling

Be careful, you could drive yourself mad.
Now reverse it and think just how small an electron is.
Now think of how small quarks and gluons are to the whole universe (beyond the observable universe), and then think of how many plank lengths fit into the whole universe, and remember, there is a possibility of a multiverse.

@@helo9316 True, but you never know, we might be the only ones alive in the universe, and that itself means we are special and unique. It's not that we are tiny, it's just that everything else is really big, well at least on a human scale. Also you never know, in a few million years, maybe the solar system WILL depend on human activity to exist, but I get what you're saying. Just trying to be optimistic.
The fact that, as creatures we are conscious of what is around us has to be called Magical!
So true, no other life form has this burden, or experience.
So difficult to comprehend “no end”…..just for ever and ever.
But it has an end, and that is also difficult to comprehend.

The edge of the observable universe is NOT 13 billion light years away. It is closer to 47 billion light years away. This is because the universe has been expanding while the light was travelling.
EebstertheGreat No. It's actually 93 Billion LightYears.
TheWireFan2002 That's the diameter of the universe, not the radius. The distance to the edge of the observable universe is the radius, which is half the diameter.
EebstertheGreat So you're saying were right in the center of the Universe? We can't be because it is ever expanding. Nothing is the center of the Universe.
TheWireFan2002 No, of course not. We're in the center of our _observable_ universe, because that's the portion of the universe _we_ can observe.
EebstertheGreat Yes but the observable Universe is also expanding. Vsause did a good video about this. We are and also are not the center of the observable Universe. There is no center of the observable Universe.
I always remember playing with Parallax using my hands as a kid but I never knew what it was called! It's funny how early astronomers could use light and Parallax to invent the "Light-Year" eventually. The representation of what the grain of sand blocks out being a Universe is mind-blowing!
One of the first lessons of astrophysics is humility; us humans are more insignificant than a grain of sand compared to the scale of the universe.
Things get equally mind-baffling when we look at things on a smaller scale. There might be more stars in the visible universe than there are grains of sand on earth, but in that grain of sand there are more partices than there are stars in the visible universe. Atoms in that grain of sand are also very, very distant from each other. If you would take a tiny marble ball and think its the core of the atom, its electron field would be around 50 meters away from it. And between different atom’s electronic fields, the distance gets even more immense. The scale of things is just as ”large” with small things as it is with big things.
Each one a universe in its own.
Doing the math, there is probably about as many stars in the universe as drops of water in all the Earth's oceans combined which is mind-boggling.
Wow I just loved everything you’re saying thanks for taking the time to write that(4 yrs ago😂) it hurts my brain just a little less and more at the same time 💙
THanks for nothing. Now I´ve got a headache.
look at all those stars and galaxies there is no way we are alone in universe

It's crazy to think you could just keep going an going forever all eternity an never reach an end to the universe 🤯
His grain of sand analogy at the end reminded me of a book called Powers of Ten that I read years ago. It was a view of earth basically that begin from somewhere far out in the universe and moved closer by a factor of ten each step until you were at the subatomic level.
thats a cool book
Even if you could go 1,000 times the speed of light, it would still take 100 years to cross the Milky Way galaxy.
hawaiidispenser wait until Andromeda and milky way clash and become a super cluster. 5 billion years may seem like a long time for us. But that's a mere blink of an eye as far as the universe itself is concerned.
That is why wormhole was invented to travel accross the universe
and that's just the Galaxy
hawaiidispenser you meant 100,000 years?
no, cause he travels at 1000c, as he said.
Now imagine the universe is just an atom in this larger universe
tangente00 that doesn't work because electrons don't "orbit" the nucleus of an atom in spherical orbits like planets round stars or stars around galaxies. common misconception however
And after that you got the multiverse theory.
We know that atomic particles aren't mini universes. They have unique properties, the same way the universe has unique properties.
they say that if an object is 1 billion light year away , it means that the state of object we see right now is actually 1 Billion year ago's state. if it's true then how could be observable universe is till 91 billion light year away ? Big bang itself took place 13.8 billion years ago then how can we see object beyond 13.8 billion light years away ?!!!
The universe expands faster than the speed of light
Nothing quite like watching a short TH-cam video about the vastness of space and realizing how small and insignificant you really are. Thanks.
Every two to three months I come back to this and things are taken into perspective.
I think the single most depressing feeling I've ever had in my life, more than heart break, more than losing something I cared immensely about, is that I will never get to see all this universe has to offer. All the galaxies, the stars and worlds that exist out there that I'll never see, the possibility that there's other life and I'll never know. The beautiful clouds of gas, the bright glow of a white or blue star and the truly cataclysmic destructiveness of a black hole and surrounding event horizon. Knowing that with all the beautiful things I've seen on earth there could possibly be billions of billions more that are equally or more magnificent than those. But most of all that on a planet of 7 billion people, thinking about never really knowing who else is out there gives me a crushing loneliness. I don't know why but thinking it's just us makes me extremely sad I can't just leave to go look, jump in a ship and take off to see what's out their. I envy the generation that gets to do that and at least if I can't I can contribute enough that the dream stays alive in through the ages.

Have not those who disbelieve known that the heavens and the earth were joined together as one united piece, then We parted them? And We have made from water every living thing. Will they not then believe?
Quran, Surah Al-Anbiya, Verse 30
Say Nada Fuck Islam.
And within this depressing feeling lies a bright possibility that somewhere, out there, lives a Civilization which will one day reach our corner of universe and pull you and me from the past memories to be resurrected as better life forms. Then, maybe, we get to see everything or better than this time. A fantasy maybe but the sheer scale and awesomeness of universe makes me feel that there are surprises out there. Wonderful and better surprises

Galaxy update : it has been verified that the amount of galaxies in our observable universe has increased from 100 billion to 2 trillion. ✔️
Jordan Mokricky Observable...how much is not observable? I can’t even think about those numbers.Infinity is too much for us but I think we have to talk about infinity.
Mr John well the universe is expanding quicker than light itself and with that expansion the newer forming galaxies light isn’t fast enough to reach us no one fully knows the extent of how Large the known universe is but it could be billions of times lager if not more but we’ll never know.
@@sport-shorts according to Dr. Alan Guths theory of cosmic inflation, if the universe began when we think it did (14.5 billion years ago) then the entire universe is approximately 150 sextillion times larger than our observable universe. Think of it as though we live inside an exercise ball (our observable universe) here on earth but us inside the exercise ball were completely oblivious to earths existence. That's basically the exact same thing.

I get the feeling that the universe is a grain of sand to an ultra-universe. There's no end...it keeps going.
The fact that some people think we are alone in this universe is so stupid. How, out of 100 billion galaxies, could we be the only ones.
100 billion? There's 2 trillion galaxies just in the observable universe alone which is just a tiny fraction of the entire universe. The entire universe is estimated to be 150 sextillion times larger than the observable universe.
I think there’s a good chance we are alone out here. And I’m not stupid.
@@brandonneumann5294 how do you even get the number 150 sextillion? I think that number goes WAY farther than that! I don't think the numbers ever stop, considering the universe does not have a wall at the end of it. Because, it goes on forever!
@@terryshubitowski9395 Idk i remember reading it somewhere. It might be infinite but i don't think so considering the universe is always expanding. If it was infinite it wouldn't need to expand
@@brandonneumann5294 150 sextrillion? That is a lot of sex, no ?
When I was a kid in elementary school, I was reading in our science textbooks and saw like several nearest galaxies and was like, “I wanna visit those when I get older” but I guess I overlooked the fact that there’re more galaxies than we can count and we have no way of transportation that can reach another galaxy.
Out of all videos I've seen on the subject, this one felt most concise in terms of scale and space-time.. which can't be easy to condense into six minutes and change.
"1000's of galaxy's within a patch of sky the size of a grain of sand"
My Brain: Bye! You comprehend that. I'm out of here".
hahaha cute comment. :)
10 000 galaxies.
It is the exact same concept as a mountain in thedistance the size of your finger nail holds thousands of trees
Its the size of a grain of sand because it is so far the further you go out the more your view expands.
I am to follow
It really is mind bending trying to imagine the size of the universe. The earth cannot possibly be the only planet able to support intelligent life in the universe. The chances of us bumping into each other however is infinitesimally tiny. Our star is hardly remarkable among a sea of 200 billion just in our own galaxy, not to mention the over 100 billion other galaxies out there. Space is also very roomy, our nearest star is multiple trillions of miles away, even asteroids have millions of miles between each one. In short, the chances of aliens coming across us accidentally must be less than the chance that men's and women's minds meeting in understanding. This stuff really is mind bending and I love it
Theoretically though since we plan on living forever, it's inevitable.
Yes, but when you consider how much of the universe is composed of dark matter/energy and the theoretical density of such matter the space could actually be quite full of "stuff" that we just cannot see.
And don't forget guys the universe is expanding with the speed of light ...that means that galaxies and other stars are moving away from us.. We need that technology soon lol
mathematically speaking, the possibility of an occurance in an infinite time and distance is 100%
I don't get it
Chances are high that the universe is infinite - just as time is. 99.9% of human beings have absolutely no concept of infinity...
100% and we are in a firmament
@@Footballyoungsterss You can call it that, but even if that's true, the firmament is contained in infinity.
Thank You for this video.. I just saw this today. When I contemplate the cosmos (and I do this every day pretty much) I am awestruck by the incredible size and age of the universe when compared to the speck of dust in some backwater arm of our galaxy that we call home. I marvel at the difference between what we as humans know and the vast array of science, history, epistemology and metaphysics that we may use to describe and come to terms with our relative place in these cosmos. It is utterly fascinating. And it is in a sense ironic. The irony is that even with all our giant telescopes and microscopes we have yet to discover any structure as complex and nuanced as the human brain. So magical and yet so utterly common on our planet. Such thoughts can lead us down many avenues as we try to unlock the story of both our own past and our place going forward in time. Is the human brain unique to our planet? Or is our brain replicated elsewhere in the universe. I honestly don't know. But such topics as this leaves us to ponder and re-evaluate our existence and its meaning. It is something I think about often. And if you made it all the way to the end of my impromptu tract, thanks for hearing me out. I think we are best served when we discuss these matters often. So thanks. I am done for now.
@PaulAnderson: Thank you for your post. Well said!

Absolutely mind blowing! Reminds of how small we really are!! To think there is no other sustainable life out there is absurd!

❤️
Yes, Fermi's paradox.
Watching this before my new job- makes me feel much less nervous hahaha
Quality thought provoking subject here and excellent job done at conveying the profound enormity of it. Using the cathedral and grain of sand to show scale comparisons was brilliant.
At the time of this video being made, physicists and astronomers thought the universe had 100 billion galaxies in the observable universe...
Now we know there is over 2 trillion or possibly millions of times bigger than that, so a better comparison with this galaxy relative to the universe would be that grain of sand in comparison with our whole planet at least!
Bill Murray that’s depressing. 😦
The universe is infinite, it keeps expanding infinitely.
@Xattack21 1 i agree we still have a looooong way to go to discover whats beneath us and what lies beyond. I even heard that there are other multiverse or dimensions, so we really couldn't possibly comprehend everything
@Xattack21 1 because ocean floor are hidden and difficult to explore while space is open and you only need the time for light to reach the telescope.

How do we know that Andromeda Galaxy still exists if we are looking into the past? 2.5 million years ago?
Sandeep Ozarde Because space is so big even if it stopped existing 2.5 million years ago it wouldn't have drifted apart enough for a huge significant change.

The most underrated comment on TH-cam 🤣🤣🤣🤣
He was using a slide rule! Give the guy a break! :)
I think you meant 0.027865"
LMBO.
the ending was a let down. i thought he was gonna say, “the grain of sand is our galaxy. and the universe is the entire earth.
He got that last part wrong. I think he meant all the sand it would take to build the cathedral, but the space between galaxies and therefore "grains of sand" would be very far
So if we go by the theory that we are looking the past ..doesnt that mean currently there might be life out there but unable to detect due to light speed constraints???
1. "The Universe" is big but that means it ends sometime/somewhere... what's past that point?
2. If seen from Andromeda, the Earth appears unhabited, then we have pretty low chances of being seen by other civilisations. And there are other civilisations, in a form or another. Maybe they'll se us in another million years watching cat videos on facebook.
The human race is self destructive. It'll wipe itself out within the next half a millennium, so I wouldn't worry about being embarrassed and getting caught masterbating or watching cat videos by aliens.
DucatiMeccanica You haven't learned anything did you? If someone will sometime watch us seeing cat videos that would be in alot of years, i mean alot cause the light needed to travel from earth to that planet where they can see us from.
iwillieyou Even if we all die tomorrow, as long as other advanced life exists, we will never be truly gone.
TheLMMish Nothing is past it. After the universe is nothing. If you travel to the end of the universe you will just fall off into nothing. Just like how when we traveled a certain distance from Europe and Africa, we would just fall off the face of the Earth because the Earth was flat. At one point, we could not comprehend how big the Earth was and what else was out there. We will eventually (maybe 100 years from now, maybe 1 billion years from now) learn more about the universe and what is really out there. Until then, keep your imagination open.
DucatiMeccanica LOL What's wrong with watching cat videos?
the best video i have ever seen about the universe size
*I don't understand the concept that a star located 13 billion light-years away from us is necessarily closer to the origin of the universe. In the analogy of an explosion, some fragments are ejected earlier than others, but their distances apart are a separate matter. While a galaxy situated 13 billion light-years away from us might be distant from the center of the explosion, it coincidentally aligns with our 13 billion-year distance. This alignment doesn't inherently imply it's closer to the universe's explosion origin.*
I have never thought about what someone on another galaxy with a super powerful telescope, powerful enough to see persons on earth surface could actually see in this moment... THAT blew my mind away. I do know and understand that when i see a star, i'm looking at the past; billions of years in the past and that maybe that star doesn't exists anymore, but i had never before thought about someone on another planet, looking at us in our past... mindblowing
+Antonio Carranza For them we are cute little dinosaurs :D
Dinos be like. Hey! Wat yo looking at?
imagine if we someday come in contact with human beings that are a million years ahead of us?
so correct me if im wrong - if had a ship and was able to jnstantly teleport myself to a point in space lets say 300 hundred light years away and come back to earth i would end up time travelling and returning to earth 300 years ago?
+Tyler Summerlin yes thats the antichrist. and we will see him in about 15-20 years.
I really loved the analogy of what Earth would look like from another universe, and what time frame it would be and what they would see.
So the aliens think dinosaurs still roamthe earth.
@@nazmulslater8398 they would...now that is truly messed up to even imagine that
@ it is truly insane to think about
@@nazmulslater8398 Only if they were looking from a galaxy 65 million light years away.
if we look from far away we could even see earth being created
I wanna become a light to travel through the galaxies all my life!
Nice
Be careful I'm a black hole😈
@@ELjour1455 no worries, I'd take the long way round 😉
I didnt quite understand the analogy, but your video was helpful.
I have been watching you video around 40 times every year ..... THANKS
4:25 thought he was f uing the sky ;/
me too lol
Lmao
ahaaaahaaa
This made me actually laugh out loud
In a world where I feel so small I can’t stop thinking big
3:40 - Wow 2.25 MILLION years for the light to reach us from the Andromeda Galaxy. Cliff Richard would have still been a kid 2.25 million years ago!
Thanks for the video
Bro just try to imagine how far a light year must be when light travels around the world 7 TIMES in 1 second!?!? Unreal
186,000 miles per second. The numbers are staggering and it is fascinating to think about how big our galaxy (the Milky Way) alone is at 100,000 light years. Crazy! Science is fun!!
There are some stars that big light take 9hrs to go from pole to pole 🤯🤯
@@1bcordell 9 million mph
The whole "you're looking at Earth from Adromeda" scenario is so flipping cool I don't think my tiny human brain can comprehend it
Our galaxy is a grain of sand in a universe that is a grain of sand in never ending space.
So does the universe have an ending? Or doest it have a corner? Or is it limitless? Or its just like earth who's round in shape but bigger or anyone? Any idea? Its mind blowing.
Absolutely fantastic. Very well presented and very understandable thank you.
I'm sorry, I got a headache trying to comprehend all this. Thank the heavens for Tylenol...
4:24, I do that all the time when I fail my Astronomy finals, only switch the fingers
Thank-you for the video, it gave me a better perspective on how unfathomable the size of the observable universe.
I'm still trying to wrap my head around the number of stars being more than the number of grains of sand contained on Earth. I then think of the vastness of the Antartic, Artic, Sahara, Arabian, Australian, Gobi, Kalahari, etc. deserts and my mind starts to hemmorhage....Another head gasket officially blown! 🤯
I think it was Woody Allen who said " Eternity is an awfully long time, especially towards the end" Lol.
Tony Lloyd haha, Woody is the best!
No Woody Allen said............ She maybe just ten but what the hell...
Christos Shugeh...you just made my morning....LOL
