'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
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
Blows my my mind that light from stars is is actually older than the Earth itself & our closest star is 25 trillion miles away.🤯

The universe is a nothingness that seems like something.

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.

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

@@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 milky way cathedral analogy actually made the universe feel small.

@@nickmiller76 it’s all relative mate, scale invariant fractal, whatever you care to call it, the pattern repeats and can be seen or experienced at any scale. Big or small depends on the framework you choose and, being human, we tend to use ourselves as a yardstick. A grain of sand is effectively infinite to a gluon and our cosmos could be but a mote in a multiverse but, as Blake illustrated, it doesn’t matter to some.
I remember a film they showed us in high school earth science. The guy in there said that if our solar system was the size of a quarter including Pluto, then the Milky Way would be as big as North America. Blown mind.
Crazy to think about
Having watched hundreds of videos about universe over the past few days... I can say this one is certainly one of the best and most simplest videos about universe and its size.
Yeah this one is fab!
In the first 10 seconds, we get "vast, enormous, immense." Every sentence of every British science documentary must sport at least two random adjectives from a list of about 30 that start with "vast, enormous, immense." So sorry. This is where I get off the bus. I can't stand it.
Some people can't comprehend the shape and size of the earth, and now you want them to imagine the size of the universe?
Dude, some people even have no idea that International Space Station exists
Cos they believe the earth is flat. And the firmament around the disk has the stars dotted in it.

@@passenger6619 it exists, not in the sense the name points the average person to but somethings out there, astronomers have weighed it and its come back with a weight so it's just a case of figuring out what it is and how to comprehend it
I get the feeling that the universe is a grain of sand to an ultra-universe. There's no end...it keeps going.
Hey I'm from another dimension. Who told you this information? Was it Bill? He's the worst at keeping secrets.
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.
For all we know, that grain of sand could be the universe itself

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.
Our galaxy is a grain of sand in a universe that is a grain of sand in never ending space.
look at all those stars and galaxies there is no way we are alone in universe

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.

Bring me Peter pan Exactly my feelings..read a wonderful quote somewhere.. "Born too late to explore Earth in a meaningful way, born too early to explore the Galaxy"
Bring me Peter pan .. Do you think God has created this. It is Jesus who learned us this.
Pan, Don’t be depressed or lonely. You can rid yourself of both now, and get to see the answers you seek later. It’s all possible, if you know where to look. It’s joyous knowledge! The haters and atheists may fight to keep you from what you long to see, but God loves you, and will gladly reveal his secrets to you. Seek him, and fulfill your dreams.
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.
This is a great therapy for me. I quickly realize, the problems we have here, are so meaningless. I Just love listing to these amazing stories!!
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
Takes my breath away just trying to imagine how vast it could possibly be...
It could possible be Infinite expanding every second
Thought only covid took your breath away
It isn't vast, I can deal with vastness , It's endless and that's what bewilders the mind.
"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
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!
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

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.
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.
and that's just the Galaxy
hawaiidispenser you meant 100,000 years?
no, cause he travels at 1000c, as he said.
It would take 100 years for the person who is watching. But the person who is travelling, time stops.

I actually thought of it as if the milky way was a grain of sand, the entire universe would be planet earth💥
Yes that is what I thought too. I was underwhelmed.
Actually, its more like the entire universe and the observable universe, is what the observable universe and our planet is. Hope that makes sense.
Perhaps the observable universe is the grain of sand, and the entire universe is the planet earth.
@@romanticdonkey468 I can dig it✌🏿
Agree with this, but I think infinite earths are squished together like bubbles
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!
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!

It was a great read📚✨
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.

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.

That's basically the exact same thing.

Thank you this is the best simplified description of the universe ever presented.
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.

thats a cool book
How do we know that Andromeda Galaxy still exists if we are looking into the past? 2.5 million years ago?

*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'm sorry, I got a headache trying to comprehend all this. Thank the heavens for Tylenol...
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
I think if you did try to comprehend the size of the universe I think your mind will crack and you will be insane
Every two to three months I come back to this and things are taken into perspective.
He seems so excited on how big the universe is
Well! aren't you???
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
What blew my mind was he said the "visible" universe. Who knows what else is out there!!
If the universe is infinite, no lenght of numbers matter, since there cannot be a number great enough to beat that which has no end.
When you wanna go somewhere and think it's far, just remember how small the earth is compared to the Universe.
4:25 thought he was f uing the sky ;/
me too lol
Lmao
ahaaaahaaa
This made me actually laugh out loud
Are we alone in the universe ? No, how do I know that? I don’t! And that’s what I love about the discussion. I just believe we are not alone. And I definitely do not believe the earth is flat!
Stephen Hawking agrees with you. Neil deGrasse Tyson agrees with you. Loads of serious scientists often cited (erroneously) by atheists agree with you.
@tinwoods I'm curious where anybody finds said science today? I find a lot of belief called science but extremely limited actual independent objective science. Hence the argument that science is somehow a better alternative is ludicrous.
I had a dream once as a kid .. it was a dream about the biggest and the smallest and that the two are infinitely the same and endless. Not sure why I had the dream being such a young person at the time.... I don’t remember contemplating such profound thoughts at 12 years old. Weird
Imagine when we die we meet the creator of the entire universe. He was silently watching us all this whole time. We now have to be accountable for everything we did especially at those times when we thought no one was watching us 😥
Compared to my youth when I was 8, I’m now 18 and I can’t see any stars at night. Green house gases in the atmosphere is responsible for this I think. I remember it was beautiful looking up at night and seeing endless amounts of stars
the world is brighter in terms of Light pollution than it was 10 years ago and this makes seeing stars more difficult than ever before especially if you live in a city or next to one. :(
Light pollution, I went camping this weekend, I saw sooo many stars. You can’t blame everything on climate change
@@ElijahMendiola Yeah, the Gov.actually believes what he is saying !
My father used to blow my mind as a child when he explained infinite largeness and how it related to infinite smallness. That we are somewhere in the middle. Take the tiniest thing we know, the atom. Well it has mass and because of the limits of our technology TODAY, we view it as the smallest entity we can record. Well anything with mass can (theoretically) be cut in half forever and ever. Now apply that logic to the unknown size of the universe. Humans can't grasp the concept of of infinite largeness because our sanity revolves around being able to measure EVERYTHING. But if we were able to travel to the end of the universe, what's on the other side? My young mind..............blown.
Apparently there's a restaurant at the end of the universe.
Wow. Your father knew you when he was a child?

I watch this video at least once every year since 2013... just to makes me cry... Thank you

Just to CRY
This man is my age... as we both took a different path, I was with this man in the same Country at the same time too, must passed each other path, as strangers, each took different path, due to Circumstances, how I wish we could meet in person today, just to compare notes and views...
Here I watch it yet again

Comparing a grain of sand to that that of a human is like comparing human with solar system is like comparing solar system with universe. Genius
makes you think: Why. Why are we here. How are we here
Ask Ilya Bryzgalov what he thinks.
Take It Easy - I'm Easily Offended alislam.org is the answer lol
Durka Durka
Why on earth do you need a reason to be here?? Can't you just be grateful and enjoy what you have?
Take It Easy - I'm Easily Offended It really makes you think how unimportant we are when there probably is billions of other life in the universe
Everything combined that he mentions here is not even a speck of dust when your discussing the infinite. Too deep for a human brain but I still like to ponder it on occasion just to tickle it. 🤔
Compared to infinite nothing is a speck of dust, the universe is something and nothing at the same time
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
2:39 hell yeah it is

@@southpakrules That's the spirit! lol
Absolutely mind blowing! Reminds of how small we really are!! To think there is no other sustainable life out there is absurd! Statistical impossibility that there is no other planets such as our that have the correct distance from a live star and all the other makings of our solar system to create life in theirs!
❤️
Yes, Fermi's paradox.
Absolutely fantastic. Very well presented and very understandable thank you.
When all is said and done there's no beginning or end to the universe. Inner Space is just as vast too with no beginning or end.

Also him: so yeah thats fast :)
We must be fools thinking we're the only living things in the universe
But intelligent life will be very rare as each evolutionary step is luck.
@@Muralidharan001 regardless of the odds, the universe is 13.7 billion years old with billions and billions of stars. With that many chances, the low odds are meaningless.
Whether they become complex life is the question. If they can survive their great filter and evolve. Theory is we still haven't even done that yet
I think there must be intelligent life in this galaxy alone, just trapped by sheer distance from each other.
@@verybigkittens7550 100%
The problem is, literally every second which ticks by, the universe gets ever bigger.
He was talking about only the observable universe.
Actual, you are wrong. The universe is .02 inches wider than you stated. Please be more accurate with your calculations.
😂😂
The most underrated comment on CZcams 🤣🤣🤣🤣
He was using a slide rule! Give the guy a break! :)
I think you meant 0.027865"
LMBO.
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.
The Hitchhikers Guide to the Galaxy goes on to say this: In comparison to the never ending infinity of the universe, the single grain of sand does not even really exist.
And therefore neither does man. Anyone you may meet is so completely finite in relationship to infinity that they are just a figment of your imagination as you are to theirs.
There is only one person, that for a brief moment, experienced the total perspective of the entire universe all at once and his name is Zaphod Beeblebrox.
And the only thing infinitely bigger than the universe is Zaphod Beeblebrox's ego.
It's far better than that 'Goat Herders Guide To The Galaxy' bible book too many are reading instead of Mr Adams masterpiece ;)
So inspirational... Perhaps we all should watch this
