How to make a vsauce video:
1. Start with a question that sounds interesting
2. Insert math
3. Put your viewers through an existential crisis
4. Profit

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
9:15 - 9:25
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
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.
Just dropped in for a quick existential crisis. Thanks Michael, you always deliver!
Vsauce videos are as timeless as the experience of a photon

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

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.
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.

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.
For those wondering, is at 7:57

“When walking to your fridge for a snack, you will measure your fridge to be a quadrillionth of a second nearer and thinner than you would while at rest with it.”

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 😂
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.”

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?
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
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: czcams.com/video/pTn6Ewhb27k/video.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
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!

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.
One of the best explanations of Special Relativity I have seen.

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
Wouldn't it be weird if the Earth had just one sun? Imagine how cold it would get!

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'.
For someone living in a universe with 2 suns, Micheal just proved the existence of a multiverse

Nah he was just messing with us. We got 2 suns, Phobos and Deimos.

Thank you Vsauce for being the channel which helped me experience existential dread for the first time.
This is the first full v sauce video I watched. I don’t know what I just watched, but I love it.
A Vsauce a day keeps the certainty that you exist away.
not true because he does not upload daily vids
but it is true though
stil is the truth i am not being rude
r00d
keeps the *certainty that you exist away.
if there's no possibility that you exist than you certainly don't exist.
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.
This video still makes my head hurt 8 years later

9:14 imagine he said "one sun" instead of "two suns"
Thumbs up if your Earth DOES have two suns.
those dual sun earth dwellers have a dual sun CZcams, 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.

@Vsauce I loved the analogy about the speed of light and how time will be "paused", same effect was written in "Three body problem" book by Liu Cixin at 3rd book, where humans developed lightspeed and was launching spaceships to reach an edge of the universe. In theory, if there is multiple universes (you have one), and if it's "bubbles" just sitting around in a looong distance, after some t, you will reach another universe? Right?
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
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 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
An easy explanation to this question is this:
C is the speed of light, but it is also the speed at which everything in the universe travels at all times. Because C is your velocity through space, but space isn't just space. Space is spacetime. Everything travels through spacetime at the speed of C. But that speed isn't just across the physical dimensions. It includes in itself the speed with which you travel through time.
An object you are holding in your hand may be traveling through space at only a few meters per second, but it is traveling through time at nearly maximum velocity, which sum of both of these will always add up to C. When you accelerate through space, you slow down through time and vice versa.
You may not be able to travel at the speed of light, but if you were able to reach it, the simple explenation would be that, to you, the travel was instantenous. You can't perceive headlights going ahead of you when you turn them on, because the entirety of that travel period to you would have been a fraction of a nano second, which is already an understatement.
C isn't just a speed limit. It's also a time limit, a minimum speed and a constant value all at once.
Thats how you avoid a ticket. Drive so fast you can't see the officers lights turn on
9:14, are you telling me there's an Earth that doesn't have two suns?

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.

honestly sounds pretty clever for such a young age.
In reality, you didn't choose to do that, but you were chosen, in order to save the simulation from crashing
you will remember this on your death bed
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.
The precision of everything and the predisposition for many things toward life on earth. Says to me that it isn’t all random but rather created.
So we mesure our world in time space mass. But only light is constant and at the speed of light time stands still.
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.

Very original comment on a vsauce video
dude always make me question my reality
Fascinating Question!
Honestly I have to question this question because the answers don't seem accurate and inaccurate enough.
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
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.
The strangest thing I think about photons is that they have a wavelength and frequency - so, even though they are travelling at c, length contraction doesn’t work in the way you’d expect.
Heres an explanation from chat Gpt:
In our current understanding of physics, it is impossible for a massive object like a car to travel at the speed of light (approximately 299,792,458 meters per second in a vacuum) as it would require infinite energy. As an object with mass approaches the speed of light, its relativistic mass increases, and it would require more and more energy to accelerate further. Therefore, a car, even if it were somehow accelerated to a very high fraction of the speed of light, would never reach or exceed the speed of light.
However, let's entertain the hypothetical scenario where a car could travel at or near the speed of light and had functioning headlights:
According to Einstein's theory of special relativity, when an object with mass approaches the speed of light, its relativistic effects become significant. Time dilation is one of these effects, which means that time slows down for the moving object relative to a stationary observer.
From the perspective of the driver inside the car, they would perceive that the headlights turn on as usual because everything within their reference frame is behaving normally. However, from the perspective of an outside observer (someone not traveling at the speed of light), strange things would happen.
For the outside observer, the effects of time dilation would come into play. They would see the car's headlights turn on, but they would perceive the light from the headlights as traveling at the speed of light relative to themselves, as it always does. The key point here is that the speed of light is always constant (approximately 299,792,458 meters per second) in a vacuum, regardless of the motion of the source.
Therefore, even though the car is traveling at or near the speed of light, an outside observer would still measure the speed of light from the headlights as the same constant speed, just as they would for a stationary car. This might lead to some counterintuitive results, such as the light appearing to propagate forward from the headlights at the same speed, even though the car itself is moving at an incredibly high velocity. This phenomenon is one of the fundamental principles of Einstein's theory of special relativity.
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.

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

@@raptorm8242 like your pp
@@raptorm8242 proof?
Irrational numbers could be using an algorithm generating these numbers per-demand, thus eliminating the need for infinite storage.
Michael at the first few seconds of the video: "Do headlights work at lightspeed?"
Michael near the end of the video: "Are we living in a simulation?"
Lol I just love how amazing and wide ranged the topics he discussed are, you start with one question and you end up with many as while learning many other things out of that one question.
Came to see whether headlights can work in the dark but I find out that:
1. My fridge moves
2. We have 2 suns
3.I could be living in a simulation
And finally , yes they can
Why you people doesn't listen, for the 100th of time, we doesn't libe in a simulation because we have the Peeee....
Yeah I wanted to know the same thing
and u got everything wrong.
@@Muckytuja well no because the ones who made the simulation will have provided the math used for the simulation so unless we reach a higher understanding of math than them we can not prove that this is a simulation nor can we prove that it isn't one using math or anything else at todays standard
You're only living in a simulation IF you live in California.
What if you reverse in lightspeed with headlights on?
The headlights would be the same nothing changes the speed of it that's what he said
If you move backwards at the speed of light, you will see everything stand still; time stops. Because, since you are at light speed, there can not be any 'new' light entering your retinas and processing in your brain, because 'new' light can't keep up with you. So you're stuck seeing the same image; now, tomorrow, until you die, and beyond infinity (until you slow down, of course).
Also, you'd need a new gearbox because reversing at that speed will overrev your engine to the fucking max.
What if you reverse in lightspeed, but we move the lights in the back of the ship?
Checkmate.
but that is if all light is traveling in the same direction. What about the light traveling in every other direction? eg. the light traveling at you would be twice the speed. sideways? and other directions? at different ratios of that.
mind confused.
I'd think the photons would cancel each other out and just remain at that point of time it is released
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.

If you had enough headlight fluid they would.
