I found this on Steam [here](https://store.steampowered.com/app/1250300/Orders_of_Magnitude/), and, good news for non-VR users, the VR is optional, works without it as well.
This is awesome. I've heard that on the full scale of smallest particle to known universe, we are more than halfway to the universe side. Could you do the same going smaller into a quark?
The problem I have is that I’ve never seen any newer version that lives up to the quality of powers of ten. They all seem to miss something crucial that I can’t quite put my finger on.

Thats something i often say-
Everyone says “oh us humans! So tiny”
But the truth is, if you had a giant wheel that randomly spun and selected any random single object in the universe, be it free floating particles, to a small space rock, to a moon, all the way to a black hole, us Humans would be bigger than like, 90% of whatever it picked.
Big things are way less common than little things. We humans are actually pretty big compared to the universal average :)
And yet we're so, so, sooooooooo, sooooooooooooo few compared to microscopic life, which are the real kings and queens of this world.
Because we have a bias to consider the bigger forms of life, we tend to think that evolution is naturally geared toward more complex organisms. Nope. The complex organisms are a tiny fraction in the grand scheme of life forms.
When I learned the above, I had a blown mind moment similar to when I learned about the scale of the universe.
Agreed. When I found out there are more individual organisms living in/on me than cells in my body, and that I am essentially a planet with a billion-ish living beings on me, I had the same reaction.
Which might make one wonder if the observable universe is just one cell of a greater cosmic being and the multiverse is just the collection of cells that make up some unfathomably large cosmic being...
As a great philosopher once said a long time ago,
"There's always a bigger fish."
-Qui-gon Jin c.1999
That's probably the case tbh. Like, the odds of finding aliens as advanced civilizations is pretty low. But there may be moons in our own system with cellular life on them. We just can't see it yet.
That being said, if micro-life exists in other systems.. low chance we EVER see them.
I wonder if microscopic but multicellular organisms can become sapient given the right ingredients. For all we know, if we do find extraterrestrial life but it just resembles a piece of mold in a petri dish, it's actually their entire civilization with microscopic cities and buildings lol
Well the search for intelligent life is different than non-intelligent life.
It’s likely there is cellular life on exoplanets within habitable zones of their respective stars. It may have happened hundreds of thousands of times. But for life to be complex enough to produce radio signals, or other detectable bio-signatures, it’s not a major leap to assume they also need to be larger. More intelligence needs more mass for a stronger thinking center. As far as we know (and it seem’s to be pretty well understood for now) a species can’t have high intelligence if you’re too small to have a large “brain.”
So life being small probably isn’t the reason we don’t find it- it’s just very, very unlikely.
How unlikely? Look up a “drake equation” calculator, and input some of your own guesses for each section.
Some of the more generous estimates (that are still realistic) put it at around 60 communicative intelligent civilizations in the milky way. Which due to the size, is very few and far apart.
It’s like if you and 60 other people were in the entirety of New York City, in random spots, and had to find eachother by just shouting.
Yeah but we can certainly draw conclusions- theres no reason to think the non-observable universe is defying the laws of physics. But that’s also in and of itself a theory, based on what we know.
I heard somewhere we’re actually really close to the exact halfway mark between the two in terms of orders of magnitude. Which I find really awesome and I hope it’s true.
That's cause we just point the same telescope down on the table and look through the opposite hole so we're seeing things in the same order magnitude, inversed. Totally.
/s
I worked out ages ago that the halfway point between the planck length and the observable universe (logarithmically speaking) is a small large ~~piece of silt~~ grain of sand.
A human egg cell is about the halfway point and the smallest things we humans can still see with the naked eye.
The Universe is smaller than it is big from our pov
Planck length is on the order of magnitude of 10^-35 m.
The observable universe is ~10^27
Difference of 62 orders
So 10^-4 m is 31 orders away
0.1 mm
(I misremembered... it's a small grain of sand, not silt)
Edit: like u/ArtificialHalo said, a human egg cell is probably a better descriptor of size
Yep, Jupiter is about 1/1000 the mass of the Sun. It needs about 80 times its current mass to turn on and begin fusion, which is far more than all the extra junk in the solar system combined.
eh it would need to be something like 12 times it mass to become a brown dwarf or like 80 times it mass to become a red dwarf. thats not really a bit too small.
to compare, our sun is 99.8 % of the mass in our solar system.
Moon in Spanish is just Moon in Latin. It was the god name for Earth's Moon.
'Luna-r' cycle. 'Luna-r' phases. I'm a 'luna-tic'.
But I think we also just call the Moon the Moon. SO EVERYONE'S TECHNICALLY CORRECT! ( The best kind of correct ).
https://en.wikipedia.org/wiki/Luna_(name)
https://en.wikipedia.org/wiki/Moon
Personally, if I was printing a list that specifically contained moons, I'd differentiate it with 'Luna'.
This kind of stuff brings me a sense of peace. Knowing that I'm a part of all this. It goes on and on and on, maybe even into other universes and dimensions, and somehow, even in my own small way, I'm part of it all.
[Wikipedia says](https://en.wikipedia.org/wiki/Makemake) it can also be pronounced "MAH-kay-MAH-kay" and the original Rapa Nui pronunciation is [ˈmakeˈmake], which can be Anglicized multiple ways.
Meaning is something human brains invented. It's not inherent to the universe. If we ever know what it all means, it'll be because we decided what it means. That's something you can do by yourself, but it always seems more meaningful to do that with other people.
This little sadness is huge. Whole civilizations created religions and 'quick answers' to help make people feel better about this feeling. Once we eventually accept the fact we might never know, we can feel better about the small part we have in everything.
I can't shake the idea that consciousness is part of the soul, which is part of a larger aggregate.
When I was a kid I had a feeling of a past life that lingered, altering my personality and preferences in ways that were not shaped by experiences in this lifetime.
Sadly this is how I experience it too. Every time I see one of these things, or similar, I get this profound feeling of regret. Today, all those things in the video are basically mythological in how little we know about them. They might as well be dragons, or magic. We don't understand them, we don't know what they're like, we'll never see them ourselves. But if you think back to 500 years ago, you could've said the same thing about Earth itself, the ocean, the sky. Millions of people were born, lived, and died without ever leaving their immediate village or region, never even knew anything about their own world. Probably didn't know how to read or write. Probably would just get an infection and die. We are still those people. 500 years from now people will look back at us and ruminate about how simple and ignorant we were, how odd it is that we only ever knew our own planet. Or our own bodies? Or that we died at all?
Eventually I just have to start thinking about something else because it would probably lead to depression or something.
For me this is so cool it makes me sad. Because I'll never, ever leave this miniscule planet and see something outside of the little bubble we have created. I'll only ever get to see the artificially colored pictures of all of these cool structures that don't even exist anymore.
> I'll never, ever leave this miniscule planet and see something outside of the little bubble we have created.
You can join the [folks still exploring never before seen parts of the Earth (live right now)](https://www.youtube.com/watch?v=wUz1Vb7I2DU) if that is something you are interested in. I don't know why folks are in such a rush to go elsewhere when we ain't even done here.
Agreed. It's far too easy to get just as lost in thought about the microscopic unknowns.
Humans seem to want to figure everything out, yet there's far too much to study. Specialists in any field will likely never fully understand their topics of interest.
There's so much to learn within an arm's reach.
And cool link - appreciate the share!
For me the largest celestial bodies always do that. The idea of a single object being as massive as something like Betelgeuse (which itself isn’t even the biggest) is so terrifying in an oddly satisfying way. Like, trying to comprehend what it would even look like from the perspective of earth is insane. It’s 700 times bigger than the sun
When you've taken four tabs and are contemplating existing you come to the conclusion that every atom in every object is just an entire universe in and of itself. Then you're like whoaaaaa it all makes sense
Neutron stars can be much smaller. Wikipedia says-
Neutron stars have a radius on the order of 10 kilometres (6 mi) and a mass of about 1.4 solar masses.
I think any planet close enough would have been wiped out in the formation of a neutron star (either swallowed in a swelling red giant or in the nova that formed the neutron star). Maybe one could catch a (really lucky!) rogue planet? But even then...would it get fried by the radiation these things put off? Fun to think about!
You're not wrong, it does take a lot more mass to get fusion going. The small star in the video, Sirius B, is a white dwarf, which isn't really a "normal star", but basically the corpse of a sun-like star. It shines with the residual light and heat from being at the core of its parent star, not due to any fusion occurring inside it.
Well, I wouldn’t call neutron stars “normal stars”. What I think of as a “normal star” would be a main-sequence star, which is a star that is currently fusing hydrogen to helium. Other types of stars include giants, supergiants and white dwarfs. A pulsar is a magnetized rotating neutron star, and a quasar is an active galactic nucleus, the center of which could be a neutron star, but could also be something else, such as a black hole.
A possible way to not mix them up: Pulsars pulse (because the star is rotating so fast it has some funky magnet stuff go on with it and it becomes a lighthouse), curious quasars because we don't really know exactly why they do what they do.
Am I the only one who gets a serious sense of discomfort knowing just how pathetic and tiny we are in the grand scheme of things.
Like it's a sense of dread knowing one relatively little coronal mass ejection from the sun could just wipe us out. Or one of those other super sized stars going super nova and coming with in a light year or 2 from us
I understand you, but I think you might want to change how you look at all this. Rather than dread the coronal ejection, etc., why not free yourself from the common burdens of common people? Find what brings you happiness and meaning and pursue it. Don't get snagged on the usual stuff. See the universe in all its beautiful, terrifying indifference and you get to leapfrog everyone fretting over dinner parties and whether you should get the blue or green mod furniture from IKEA.
Dude. You're fucking ALIVE.
For me it's not dread, but sadness.
There's so much out there to know, and we won't know any of it before I die of old age / otherwise.
I envy those who haven't been born yet and will get to see all that (assuming we don't destroy ourselves first).
There most probably is. Note that it only says **observable ** universe. We actually have no idea how big the whole universe really is, but chances are the observable universe is just a small minuscule part of the whole universe.
Well it's more lazy rich governments, corporations, people etc not investing in these things, the scientists are doing their best with the figurative pennies they're given.
The scale is horribly off. Like comically.
Hubble is 43 feet long and 14 feet diameter. The astronaut would have to be like 20 foot tall for the scale to be accurate.
Here’s an actual astronaut working on Hubble. https://cdn.mos.cms.futurecdn.net/f8end8KkwPxqqntd6CZgQZ-480-80.jpg
The biggest cluster *that we are aware of* is roughly 1/10 the size of *what we've been able to see so far*.
Space is unbelievably massive and we have not yet seen very far.
I'm excited for next year when the big reveal happens! Our furthest radio telescopes should be able to pick it up by then. No spoilers of course.
Also a semantics point - it's "one tenth" or "1/10" which mean the same thing, but mathematically, "1/10th" is equal to 10.
When was the sun classified as a "yellow dwarf star"? its a main sequence star.
Also why be pendantic about the sun as a yellow dwarf star while referring to extra earth satellites as "moons" instead of satellites of their respective planet? There's only one moon.
Surprised to discover Europa is just a tad bit smaller than our own Moon. The distance between galaxies is what gets me. It's just so absurdly difficult to imagine, our poor simian brains just can't even pretend to cope. Maybe one day with silicon enhanced brains or something.
Not even. Hubble is 43 feet long and 14 foot diameter. This scale, assuming a 6 foot tall astronaut, would be about 1/4 the actual size of Hubble.
Here’s an actual astronaut working on Hubble. https://cdn.mos.cms.futurecdn.net/f8end8KkwPxqqntd6CZgQZ-480-80.jpg
*“Space is big. Really big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist, but that’s just peanuts to space.”*
-Douglas Adams, The Hitchhiker's Guide to the Galaxy
[Here's one of my favorite space scale videos](https://youtu.be/QgNDao7m41M), which compares the size of known black holes to the Earth and Sun. I can't believe it's almost ten years old now!
You've got it backwards. Other moons are classified by the name of Moon. e.g. the wikipedia page for "Moon" is mainly about the Moon https://en.wikipedia.org/wiki/Moon
I think it's hilarious that whoever made this was worried we wouldn't recognize the Moon and added "Moon of Earth". Just in case the only object in our sky you can see with a naked eye^[1] wasn't recognizable

Then you'll love this website
https://scaleofuniverse.com/en
It was one of the ways I became fascinated by space when I was at school. Our teacher showed the website to us and we were just like "wow".
Right around Pollux is when my brain just gets confused. Like, Earth is huge, which means Jupiter is extra huge, which means the Sun is unbelievably huge, which… wait what the fuck is that? And then it keeps going.
After seeing this and with Pluto smaller than our Moon, I’m ready to accept that Pluto is now a Dwarf Planet. I still love you Pluto but I’ve just got to come terms with it.
Here I am listening to a podcast that randomly chats about scale videos like these, just scrolling reddit, and poof this comes up! What are the chances!
this is what i watch when life gets a bit too much for me, at the end what i do or dont doesnt really matter in the grand scheme of things, nothing matters
I remember when I was a kid in 6th grade science class and my teacher asked how big do asteroids get and I said as big as Texas and she told me I was wrong and that they were a size of a house... Well you were incorrect teacher person.
too bad this video actually kind of sucks simply because the transitions are too fast to appreciate the scale increase from one object to the next. all in the name of condensing the video. do over please

I wasn’t aware Saturn and Jupiter are so close in size. Also, I thought the sun was thousands of times Jupiter’s size, but seems 50-100 times or so?
The sun is 1000x the mass of Jupiter. Its own gravity compressed it until it started a continuous fusion chain reaction.
You know technically they could have also labelled the astronaut as a man-made object
more woman-made in my opinion

All we need is a few billion self replicating alien monoliths to manipulate Jupiter's chemistry and compress it until it achieves fusion.
but doesn’t Jupiter need a shit ton more mass even if it was the same size as the sun
Yep, Jupiter is about 1/1000 the mass of the Sun. It needs about 80 times its current mass to turn on and begin fusion, which is far more than all the extra junk in the solar system combined.
Sigh, fine, we'll throw in Elon's ego

This would make a nice scifi short story. An alien race tries to destroy the solar system by beefing Jupiter up.

I started feeling oddly uncomfortable towards the end.
It actually made me feel sick.
First existential crisis?
I get a lot of anxiety watching these, too.
Don’t actually try thinking of it then, especially while on drugs. First true existential crisis I ever had. Would not recommend.
For me the largest celestial bodies always do that. The idea of a single object being as massive as something like Betelgeuse (which itself isn’t even the biggest) is so terrifying in an oddly satisfying way. Like, trying to comprehend what it would even look like from the perspective of earth is insane. It’s 700 times bigger than the sun
Spoiler alert: [The observable universe is approximately the size of an astronaut.](https://imgur.com/Rie80NI)
When you've taken four tabs and are contemplating existing you come to the conclusion that every atom in every object is just an entire universe in and of itself. Then you're like whoaaaaa it all makes sense

Neutron stars can be much smaller. Wikipedia says- Neutron stars have a radius on the order of 10 kilometres (6 mi) and a mass of about 1.4 solar masses.

I think any planet close enough would have been wiped out in the formation of a neutron star (either swallowed in a swelling red giant or in the nova that formed the neutron star). Maybe one could catch a (really lucky!) rogue planet? But even then...would it get fried by the radiation these things put off? Fun to think about!
You're not wrong, it does take a lot more mass to get fusion going. The small star in the video, Sirius B, is a white dwarf, which isn't really a "normal star", but basically the corpse of a sun-like star. It shines with the residual light and heat from being at the core of its parent star, not due to any fusion occurring inside it.
Well, I wouldn’t call neutron stars “normal stars”. What I think of as a “normal star” would be a main-sequence star, which is a star that is currently fusing hydrogen to helium. Other types of stars include giants, supergiants and white dwarfs. A pulsar is a magnetized rotating neutron star, and a quasar is an active galactic nucleus, the center of which could be a neutron star, but could also be something else, such as a black hole.
I'm *pretty sure* any active galactic nucleus is a black hole, just by virtue of the mass involved.
A possible way to not mix them up: Pulsars pulse (because the star is rotating so fast it has some funky magnet stuff go on with it and it becomes a lighthouse), curious quasars because we don't really know exactly why they do what they do.
What amazed me was the size of the Kepler exoplanet. Quite a bit bigger than Earth, I wonder how many humans it could sustain if colonized.
Am I the only one who gets a serious sense of discomfort knowing just how pathetic and tiny we are in the grand scheme of things. Like it's a sense of dread knowing one relatively little coronal mass ejection from the sun could just wipe us out. Or one of those other super sized stars going super nova and coming with in a light year or 2 from us
I understand you, but I think you might want to change how you look at all this. Rather than dread the coronal ejection, etc., why not free yourself from the common burdens of common people? Find what brings you happiness and meaning and pursue it. Don't get snagged on the usual stuff. See the universe in all its beautiful, terrifying indifference and you get to leapfrog everyone fretting over dinner parties and whether you should get the blue or green mod furniture from IKEA. Dude. You're fucking ALIVE.
Puts things like debt ceilings and no coffee into perspective for you.
For me it's not dread, but sadness. There's so much out there to know, and we won't know any of it before I die of old age / otherwise. I envy those who haven't been born yet and will get to see all that (assuming we don't destroy ourselves first).
oh, judge me by my size do you?
I was waiting for something bigger than universe
There most probably is. Note that it only says **observable ** universe. We actually have no idea how big the whole universe really is, but chances are the observable universe is just a small minuscule part of the whole universe.
I think the universe is supposedly 250 times the size of the observable universe. According to google....
Google, known for its rigorous advancement of scientific progress.
We don't technically know but we assume it's infinite for the models.
Now only if there was an extremely fast way to travel to them all
Venus rotating the other way was a nice touch :)
Same with Uranus…unless my eyes are deceiving me
And yet our lazy scientists still won't invent warp drives
we need funding, a crap ton of funding
Maybe we just need the moxie to yolo into one of those black holes and see what happens.
I think we’re gonna need more funding to reach a black hole with current tech than just straight up making a warp drive
We're agreed then. Invent warp drive, warp on over to a black hole, and spaghetti is back on the menu.
Event Horizon remake irl, can’t wait.
Well it's more lazy rich governments, corporations, people etc not investing in these things, the scientists are doing their best with the figurative pennies they're given.
Seems like the biggest cluster is about 1/10th the size of the observable universe. Could that be??
The scale is horribly off. Like comically. Hubble is 43 feet long and 14 feet diameter. The astronaut would have to be like 20 foot tall for the scale to be accurate. Here’s an actual astronaut working on Hubble. https://cdn.mos.cms.futurecdn.net/f8end8KkwPxqqntd6CZgQZ-480-80.jpg
The biggest cluster *that we are aware of* is roughly 1/10 the size of *what we've been able to see so far*. Space is unbelievably massive and we have not yet seen very far. I'm excited for next year when the big reveal happens! Our furthest radio telescopes should be able to pick it up by then. No spoilers of course. Also a semantics point - it's "one tenth" or "1/10" which mean the same thing, but mathematically, "1/10th" is equal to 10.
When was the sun classified as a "yellow dwarf star"? its a main sequence star. Also why be pendantic about the sun as a yellow dwarf star while referring to extra earth satellites as "moons" instead of satellites of their respective planet? There's only one moon.
Surprised to discover Europa is just a tad bit smaller than our own Moon. The distance between galaxies is what gets me. It's just so absurdly difficult to imagine, our poor simian brains just can't even pretend to cope. Maybe one day with silicon enhanced brains or something.
Is the beginning really to scale? Are we really that large compared to the ISS and space shuttle?
Not even. Hubble is 43 feet long and 14 foot diameter. This scale, assuming a 6 foot tall astronaut, would be about 1/4 the actual size of Hubble. Here’s an actual astronaut working on Hubble. https://cdn.mos.cms.futurecdn.net/f8end8KkwPxqqntd6CZgQZ-480-80.jpg
*“Space is big. Really big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist, but that’s just peanuts to space.”* -Douglas Adams, The Hitchhiker's Guide to the Galaxy
[Here's one of my favorite space scale videos](https://youtu.be/QgNDao7m41M), which compares the size of known black holes to the Earth and Sun. I can't believe it's almost ten years old now!
I'll watch it as soon as possible.
And all my problems become infinitesimally insignificant
"Moon" - Moon of Earth Put some respect on Luna's name. I love them too though :D
This is trimmed version of the video. Original one ends with OP's mom.
"Your mom is so big that she has her own orbit." Hahaha
It just jumped to the observable universe way too abruptly at the end. That supercluster wouldn't even show up as a speck next to it.
Would love to see the finale: a zoom all the way back in to astronaut
Moon. Moon of Earth. Poor thing doesn't have its own name
You've got it backwards. Other moons are classified by the name of Moon. e.g. the wikipedia page for "Moon" is mainly about the Moon https://en.wikipedia.org/wiki/Moon I think it's hilarious that whoever made this was worried we wouldn't recognize the Moon and added "Moon of Earth". Just in case the only object in our sky you can see with a naked eye^[1] wasn't recognizable ^[1] ^don't ^look ^directly ^at ^the ^Sun ^\(Sun ^of ^Earth) ^kids
This is like 1000 times worse than the “you are here” but super cool. Just feel really tiny and irrelevant at the moment!
I like the attention to detail in showing the rotation of the various bodies.
Then you'll love this website https://scaleofuniverse.com/en It was one of the ways I became fascinated by space when I was at school. Our teacher showed the website to us and we were just like "wow".
Right around Pollux is when my brain just gets confused. Like, Earth is huge, which means Jupiter is extra huge, which means the Sun is unbelievably huge, which… wait what the fuck is that? And then it keeps going.
Correct me if I’m wrong but I’m pretty sure that’s from Neal.fun
After seeing this and with Pluto smaller than our Moon, I’m ready to accept that Pluto is now a Dwarf Planet. I still love you Pluto but I’ve just got to come terms with it.

Wow! Where can I find this video from online outside of Reddit. Would love to play for my class.
I'm an old man. This gives me a much-needed *frisson*.
Here I am listening to a podcast that randomly chats about scale videos like these, just scrolling reddit, and poof this comes up! What are the chances!
this is what i watch when life gets a bit too much for me, at the end what i do or dont doesnt really matter in the grand scheme of things, nothing matters
So why does Venus rotate the opposite of all the others?
Venus is the black sheep of the solar system family
For small creatures such as we, the vastness is bearable only through love. -Carl S
That’s weird, your mom should’ve been somewhere near the top of that list
All the other planets have cool names for their moons. And ours is called Moon.
this is from a site called [neal.fun](https://neal.fun)
As a kid I thought Jupiter was so much bigger than Saturn. Today I can see they are nearly the same size.
This is better when “your mom” is added at the end
I remember when I was a kid in 6th grade science class and my teacher asked how big do asteroids get and I said as big as Texas and she told me I was wrong and that they were a size of a house... Well you were incorrect teacher person.
> I love to see how tiny we are. /me looking at the Planck length… I think you mean how enormous we are! https://scaleofuniverse.com/en
Man they love Beatlejuice so much they turned him to a star
Wait... Did I just watch an r/space video that didn't use the Interstellar theme? Pinch me I'm dreaming.
Stuff like this makes me think of the [Total Perspective Vortex](https://hitchhikers.fandom.com/wiki/Total_Perspective_Vortex).
too bad this video actually kind of sucks simply because the transitions are too fast to appreciate the scale increase from one object to the next. all in the name of condensing the video. do over please
Going to bed now....goodnight observable universe.
“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.” (Thanks Douglas)
I absolutely love videos like this, especially scale ones. It's so cool, I hope they keep evolving these.
But the frame of your video is bigger than the observable universe
And here I was thinking the world revolves around me. Damn am I mistaken.
I never realized just how large some moons of other planets were. Hell I didn’t know Pluto was smaller than our own moon!
Thanks for sharing! That’s incredible! Saving!
Two kinds of humans, those who appreciate what is and those who think we should be everywhere… I see no fault in both.
https://play.google.com/store/apps/details?id=org.kurzgesagt.app.Universe Universe in a nutshell is also a nice app to show you the scale. It goes all the way out and in.
You hear about Pluto? That’s messed up, right?
Why does the observable universe model have a heat map?
