Imagine if he said 1 sun instead of 2 just to mess with our heads
i was literally thinking the exact same thing that couldve been great lol
what do you mean? the earth has 3 suns.
It has two moons, too! Like Mars!
What if he said one Sun instead of two to mess with the people with two suns?
Wait am confused, we do have two suns
It's interesting to see that even after so many years none of the Vsauce videos seems old. They are ageless.
Exactly! They never feel like they came out 10-8 years ago, even if they actually did.
like the speed of light
Should make youtube contents like this, ageless
Just like photons 😉
I would say because they travel at the speed of light but well they reached my recommends feed after 7 years, so..
9:16 imagine if he said one sun instead of two
That scares me :|
I was just thinking that, it would have been a clever joke lmao
IF he said 10
(@me) binary joke
Maybe it was meant as a joke in another universe but in this one it just seems like he tells the truth
Vsauce videos are as timeless as the experience of a photon

Just dropped in for a quick existential crisis. Thanks Michael, you always deliver!
Michael:
“While walking to your refrigerator for a snack, you will measure your fridge to be a one hundred quadrillionth of a meter nearer, and thinner, than you would while at rest with it.”
Me:
“Oh good! Glad I’m not the only one who noticed…”
Can confirm. Though my measurements vary by a sextillionth of a meter depending on the time of the day.
Driving fast makes you live longer kids
Tabinda Jabeen just watch out for space bumps
4.5 years and this is by far the best comment xD
@Tabinda Jabeen or you can just go at 49.655 km per second and the color red will appear green on a traffic light
Turtlemurderer Dude watch out for space trees and space telephone poles.
You wont live longer according to you. You'll experience the same amount, so it won't matter.
turning on headlights at light speed?
ain't nobody got time for that
lolwut?
I see what you did there. Or do I? dang
i did
+Michael Lolwut What Vsause didn't say was as you or any object approaches light speed, the mass increases. So even a single proton could gain the mass of a galaxy if traveling close enough to the speed of light. Same goes for a spaceship, go fast enough and your mass will increase so high your spacecraft would collapse as a Black Hole.
And it is at that point you can turn on the headlights - but no one will have time for that :)
+Evol Bob so thats why we cant reach anywhere near lightspeed besides the factors of money and resources. Now i only need to know the point at which a ship that could achive near light speed becomes a black hole or become quite unstable because its mass would attract objects to it self.
4:02 I love you making it this scale implies that the ships are extremely massive. Like literally bigger than earth I’m pretty sure and by a lot too
Yes earth is about 15'000 KM thick if i remember correctly, while these ships are roughly 299'792 KM long 😂
He should have said, "theres a universe of you watching this video but the earth only has 1 sun" would have been a mind fuck for a second
Whoa whoa whoa, my fridge NOTICES me moving? Oh man I hope it doesn't think I'm fat.
No, I'm sure it doesn't. It probably lives in constant fear every time you go near it. This is because every time you open it you rip it's insides out, cook them in front of it and then eat it. Granted, you put more in, but the process never stops until it just can't take it anymore.
Ryan Barnes Until it just can't take it anymore... Then what happens?

I wonder if you could beat a photon in a race if you were going, like, infinitesimally close to the speed of light, and the photon was passing through some material that causes it to take a much longer path than you.
Yes you can.
well that just isnt fair imagine usain bolt not winning the gold at the olympics because someone tied bricks to his feet
Of course. There are devices that slow down photons to slower than hjghway speeds.
Nuclear reactors called, they want their cherenkov radiation back
Just keep some water in the path of your opponent 😉
Seriously though you wouldn't even realise that you had travelled
Tbh, this is one of my favourite vsauce videos of all time, it contains so much information and ideas that literally bend my brain.
Thumbs up if your Earth DOES have two suns.
those dual sun earth dwellers have a dual sun RUclips, which we don't
Is it even possible to have two Suns? Can we orbit two separate things at once? Would one sun be a moon?
Its funny because if there's a universe with two suns, then there's a universe with two suns advanced enough to watch the internet of other universes. Like Rick and Morty!
curtis mcdonald Yes. www.quora.com/Can-one-planet-have-two-suns
And no, none of the two suns would be a moon. A moon have to orbit the planet to be defined as moon. [Unless one of the two suns (or both...) orbits the planet... but it doesn't seem possible: www.quora.com/Can-a-star-orbit-a-very-big-planet ]
I can see thousands of suns from my earth. It just happens that it only orbits one.

Beginning of the video: will headlights work at light speed?
10 minutes later: are you real, or is this all a simulation?
yahhahahah
You just described 100% of every Vsauce video. Congratulations.
I don't watch vsauce anymore for that reason. It's gets to stoner mind blown shit too quick.
Because you didn't understand what he wants to say.
Harsh Deep me?
Something that helped clarify this for me is the idea that everything is always moving at the speed of light, but mass' velocity is mostly in the time direction. As a mass' velocity increases, more of it's velocity is in the space direction, so it's moving less in the time direction. With light, all of its velocity is in the space direction and none of it is in the time direction. So from the perspective of the photon, no matter how far it travels between emission and absorption, no time has passed at all.
An idea I like about why our universe turned out this way instead of another way is that if there exists a possible arrangement of cosmological constants that is most likely to create a sentient species capable of observing or otherwise deriving that earliest of moments in which those constants settled into the state that created them, then the possibility of that observation would exert a causal pressure on the uncertain early universe to settle into that state.
The speed of light is a constant. When you think about that, it's 1 of the most mind blowing things out here.
It's one of the things that can humble us mortals, who have achieved previously unimaginable feats. But lightspeed remains the same
The speed of light is unknown. It might not be even constant. There is a good video about it: ruclips.net/video/pTn6Ewhb27k/видео.html
It worked out well for Einstein.
@@innerbytes You're talking an establishment who have a habit ignoring the term _theory_ and regurgitating said theory as law. If I were a betting man, I'd bet on the speed of light being different, depending on the variables, such as the vacuum of space.
@Jerk Store I don't think you understand science, have ever taken a university level science course, or even work in a science adjacent field if you don't understand how the word theory is used. It's the 'theory of evolution'. It also 100% definitely happened, but we can't say it's absolutely true until we disprove literally every potential piece of evidence against it. Laws are for mathematics lol

Second of all, you wouldn't able to see them either.
Raffy Tabingo Well said, amigo.
Cacophonic Comedian greatest comment of of the past second
That's one good joke
Ha. Ha. Ha.
9:12 he should've said: "Some of them include you watching this video, but the earth has only one sun" to confuse the crap out of us
Despite all my research and effort spent trying to understand the world/universe, light speed is the one thing that never fails to tie my brain in a knot.
It's poorly explained because it was so poorly understood. Light travels infinitely fast but because of general relativity it seems not to from our point of view. There is no limit to how fast something can travel, just a limit to how fast it seems to be traveling from our perspective.
9:13 You should’ve said “only 1 sun” to give everyone an existential crisis
Ha, that's what I was just about to say the same thing!
hah :D a good joke missed!
Only 1 or 2? I can't imagine the solar system without 3, it would be really weird. Next you'll be saying we aren't orbiting Jupiter!
This comment is looking pretty dumb in all those universes where people have more than 1 sun.
Wait, we aren't?

What a fantastic video! You are a very good educator. Thanks a lot!
What I love about vsauce is that Michael can say something like “you can’t turn on the headlight, because you would feel like before you were conceived” , and make perfect sense in the context.

9:31 every time I hear that music, I get some serious, serious chills. I don't even know why, it just reminds me of the sheer scale and majesty of the universe and how small I am compared to it, and it's honestly so terrifying xD
maybe bc it's music with higher notes being played in reverse. The "uncanny" terror meme uses music playing in reverse for some of its creepiest sections and you might have associated that sound with fear.
There's really nothing to be terrified about, in my view. It is what it is...it's always been that way...we have to accept such things because we have no choice...and besides, we're all part of the universe in any case, as our bodies are merely 'borrowing' the atoms that comprise them. This being so, there's no point in fearing the scale of the universe, as it's merely a relative term, and nothing more.
it reminds me of an intro from the call of ktulu by metallica in one of their concerts (august 23, 2019)
Same. Well said

Even though we can never reach the end of pi that doesn’t mean that after to 10^10000 digit there wouldn’t be another one. Given we are in a simulation, would the system itself not be able to provide the calculation necessary to give us that next digit in the same way that our computers could theoretically spit out the next number. Maybe pi itself was programmed in this manner so that the simulation provides what we ask of it without having its “entire value” stored?
interesting point. But if we live in a simulation, doesn't it seem like one that hasn't been interfered with, updated, or changed in a fundamental way since it began? Laws of physics haven't changed. Pi in particular is wrapped up with a lot of these fundamental aspects of the universe. Why would the simulation continue to emergently "create" pi as we go along (change), but nothing else? Also, the theory isn't that *in lieu* of finding pi's end it shows we **aren't** in a simulation-- only that finding the end would be strong evidence to the contrary. Put another way, not finding the 'end' of pi doesn't say much about whether or not we are in a simulation, but a finite-ness to the number would point toward us being in a simulation. Until an end to pi is found, we continue to assume it can be calculated to an infinite number of digits, and no matter how large or sophisticated a simulation computer may be, it wouldn't be capable of calculating anything infinite to insert into the 'program'.
The end of every vsauce video either makes you question your own existence or just makes your day complete with a very lively quote about our existence itself. This is fascinating.
Beginning of video: would headlights work at light speed?
End of video: if pi ends then nothing is real
Woooo

A simulation is real though. To be technical anything you can experience or conceive of is 'real'. Nothing is truly 'physical' however either way.

So moving towards the fridge makes it faster to get there.
nice :D
It also makes the fridge and everything in it smaller. I call it the Special Relativity Diet.
Nadzia Skalapendra ^^
makes sense, sitting still doesn't make it faster. lol
It makes it slower to get there, but the distance is still decreased. It's just the the effect of change of time will slow you more than the distance will make you faster. Moving away will increase the distance between you and the fridge (This sounds obvious but you know what I mean), while the time you experience will still slow you down.
i love how Vsauce starts talking about things like this and then gets into the idea that we live in a simulation
Irrational numbers could be using an algorithm generating these numbers per-demand, thus eliminating the need for infinite storage.

Well not really. That just means any parallel earth that has another amount of suns that our two old boys here. Maybe Michael lives in a universe with three or more suns, maybe with just one, maybe no sun at all ? What would be funny would be if they had only one ridiculous moon though.
Micah Philson yah obviously and I dunno about you but it's a FACT that there is only one sun and it's flat

according to special relativity:
at .999c, from your point of view, the headlights will work fine, but traveling so fast causes the world outside to stretch out for you and for time outside to seem to be ticking way faster than it normally does.
for an outside observer at rest, the headlights also still work fine- but you are now moving way slower, with length contraction sizing your car down extremely thin and with time slowing down for your car as seen by the observer as well.
the reason the headlights work in both scenarios (both observers) essentially lies on the foundations of the theory of special relativity. light travels at a constant speed through a vacuum regardless of inertial frame of reference. nothing can exceed the speed of light, including light itself, neither for you (the traveler) nor the observer. thus, to keep the speed of light constant in both windows of reference, length and time are changed proportionally as to preserve c as a constant.
I'd be scared if my fridge measured my speed.
I would of legit lost my shit if he said ''you could be watching this in a universive with ONE sun, for those of you watching in a universe with one sun, that was probably confusing'' I would of actually questioned my existence more than I already do
I live in a universe where the phrase is "would have," not "would of."
whatever man, you know what I meant
I thought this same things too, he should've done the one sun thing and blown all our minds lol.
I was thinking something similar, only that we would've thought it was a joke, And we'd never know that it was not a joke.
Hiedeler H hey dude, i wrote that on an english test once as a kid, and learned its something you get when you dont hear "would've" correctly
I wish he'd have said "watching this in a universe where earth has one sun"
that would be great
wait, does your one only have one?
mine has 4 suns :/
Unfortunately, the author of this video will always observe the same number of suns as you, regardless of universe.
This. The video would be simultaneously made by a different Michael who refers to the reality of his universe.

Your videos are generally confusing, but I usually end up figuring them out. However, this one just raped my mind so hard that I don't even know if I'm real or not.....
I feel banged in the brain so baely
Can you think ? Yes. Can you do what you want ? Yes. So, what's the problem with being fake if there is no difference between that and being real ?
***** Don't worry man. Even if you are not real, you are still 'real' in your own mind.
***** Can self awareness be created artificially?
I think therefore I am.
The simulation thought process hurts my head because what if everyday that I wake up is a different simulation and only little bits and peices are changed
This is the first full v sauce video I watched. I don’t know what I just watched, but I love it.
I feel like half the time Vsauce is insanely brilliant and the other half he's just insane.
Maybe you just don't understand
Is there really a difference?
BRILLIANT!!!
Who's to say there's a difference? Or maybe the times that he seems insane is just when you don't understand his brilliance? Or maybe he's always insane, but his insanity sometimes has some brilliance as a side effect? O.o
And there's a universe where he doesn't even exist.
Damn he should've said "your Earth has one sun..." And "that was very confusing for you because your Earth does have one sun" lost opportunity.
Mahmood Muhamad Haha that would’ve been awesome ngl 😂
what if his actual Earth actually has 2 suns?
Bruh y’all don’t have 2 suns?
People in far future from different universe will see this say *lmao this guy is like Homer Simpson predicting future*
In the universe where earth has two suns, youtube comments are discussing how funny that is
9:11 should've said "some of them involve you watching this video, but the earth only has one sun. For those of you in that universe, that must have been very confusing for you, so I'm sorry."
Makes sense to me
Your comment should've been pinned for this
We need more content, Vsauce!
11:12 The problem with John Gribbin's theory I feel is that numbers don't exist within our universe and are therefor not confined to it's laws. They have laws of their own, which I don't believe would change from universe to universe. However, even if they did, any computer we created to calculate Pi would only exist within the "computer" that created our simulated universe, and could therefor only calculate Pi at the speed of the program it exists within. Also, since entropy in our universe is ever increasing, I'd say if we are a simulation, we are an active simulation that is continually being written (or actively calculated), so even if numbers were confined to this universe, and even if this universe were a simulation inside some alien super computer, we may never find the end of Pi as it may still be being written infinitely "faster" than we are discovering it. That's just my theory though.
Also this theory is relevant only if the computer where our simulated universe running has the same architecture as our computers - which is very unlikely... If our universe is indeed running inside a computer in another universe, this computer probably has a completely different architecture based on laws of physics that don't even exist in our universe, making for us impossible to actually find elements of this architecture while living in a simulated world. :)
Shut the duck up
Yeah, all true, if they can simulate the whole of world, then they can easily simulate the irrational numbers real-time. I just think that simulating everything on the quantum level would require as much computing power in terms of space and mass that you would need a computer the size of a small universe itself. (Not plausible.)
There's also a couple of theoretical limits (sort of) like Planck length/time that would nod towards an imperfect reality/simularity. That there is a granularity even if the resolution is incomprehensibly fine.
>That's just my theory though.
hypothesis.

The answer to the question was more complicated than I was hoping for.
11:59 “Irrational Numbers Keep It Real”. Now that’s a Tshirt I would buy. So many different ways to interprétate that.

This explains why the clock in my car is always wrong
Next time buy a Ford, those Chevy clocks don't work much better then rest of the car.
My car is a Ford.
You've been speeding too much. Stop and let your clock catch up.
Someone else has been driving it?
John Croucher just drive forward to your destination and backwards to your home so youre clock can catch up.
goes from a simple thought experiment to giving me one of the deepest feelings of existential dread.
I love how fast it scalated into freaking universe theories, which made my mind blow
Albert Einstein: *Gets pulled over*
Officer: “Do you know how fast you where going sir?”
Albert Einstein: “Speed is relative”
Officer:
Officer: the point of relation is the speed at which one would move at had he been standing still
Heisenberg gets pulled over.
Officer: do you know how fast you were going?
Heisenberg: no but I know where I am
@@sebastianloessl7982 Officer: you were doing 55 in a 35 zone.
Heisenburg: Great! Now I'm lost!
speed is constant
@@engineered_images Officer: That does not make sense.
Heinsberg: Who told you that?
Officer: Albert Einstein.
7:11 idk about that, man. the more videos of yours i watch the more i'm convinced that literally no one knows anything about anything
i don't even know if i'm real anymore. is this video even real?
+Jenna Trowbridge I don't know are you? Or am I in your head
+Justin Suckow ...I hope so
+Jenna Trowbridge I feel the same way.Sometimes I look at something for a longtime, after a while it starts to look virtual.
Matrix is everything. Matrix is life
In this video, Michael actually was directly responsible for giving existential dread to an entire universe.
7:00 Michael mentioned the book "Relativity Visualized" in one of his Mindfield episodes and I bought it, read it, and it totally helped me (think I) understand.
What this clip taught me: Irrationality keeps stuff real, except for light, which doesn't exist.
Hahaha exactly
light exists, it's just from its own "perspective" time does not pass, which is akin to not experiencing anything at all.
@@twally87 Time doesn't pass and space has contracted to zero for light. So effectively, from the photons perspective, nothing exists at all.
@@duprie37 oh, ok. Perspective wasn't specified initially. Just straight up said "...light, which doesn't exist."
@@twally87 Well, it's a serious ontological question. If space & time do not exist for light (not in some kind of metaphorical sense but really, according to Relativity) then how exactly does light relate to the space-time we perceive it to travel through? What is objective reality at all? Just a mirage? The more I think about it, the more I'm convinced that's exactly what "reality" is. Just a projection giving us maximum evolutionary fitness.
9:12
Meanwhile in another universe:
Michael: "Some of them involve you watching this video, but the Earth only has one sun"
"For those of you in that universe watching, that was probably very confusing because your Earth does have one sun"
He should have sayed this
multiverse is fake
@@raptorm8242 like your pp
@@raptorm8242 proof?
correct me if i am wrong, pi isnt a part of the universe, it is a number that we made up to calculate the radius and so on of circles. And there is no perfect circle in the universe thanks to the plank size, so pi is not apart of the simulation, so it doesent need to be calculated.
favorite thing about Michael is that he puts some random complex question for the title and then proceeds to explain multiple far out thought provoking ideas on the subject in a very good way. What I'm sayin is I always learn more than what I expect and I love it
Vsauce is a channel I watch a 3am
It is 5am where I am right now
same
While smoking meth
It’s 3:22am and I have work in a few hours...😩
You see freddy? Or pennywise?
If you had enough headlight fluid they would.
rooster teeth reference??
brownhard RvB :)
Cheers, Gavin
you are perpetuating the idiocracy of that statement still existing!!!! ...still funny though.
I was thinking the same thing!
When Michael talks about imagining what it’s like to be light is when the video goes on a complete tangent. But I’m not complaining!
This went from “Can we use headlights at the speed of light?” to “WE LIVE IN A BLACK HOLE.”
Classic Vsauce turning a yes or no question into an existential mind fuck
