Would Headlights Work at Light Speed?

If you were driving at the speed of light and turned on your headlights, what would happen?

Why is “c” the speed of light?

Light speed is the same in all inertial frames of reference:

Light speed and catching-up to light.

THERE'S MORE VSAUCE!!

It's interesting to see that even after so many years none of the Vsauce videos seems old. They are ageless.

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.

8:04 - you know it's going more complex when that music turns on

9:16 imagine if he said one sun instead of two

9:15 - 9:25
Imagine if he said 1 sun instead of 2 just to mess with our heads

[blazerona]

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

9:13 You should’ve said “only 1 sun” to give everyone an existential crisis

[aesp]

Just dropped in for a quick existential crisis. Thanks Michael, you always deliver!

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.

Vsauce videos are as timeless as the experience of a photon

[naryosh_]

Whoa whoa whoa, my fridge NOTICES me moving? Oh man I hope it doesn't think I'm fat.

[todabsolute]

Every Vsauce video be like:
Does sandwich always fall on the butter side?
No, you can't travel to another universe by passing a black hole.

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

[maxbateman]

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

[hammerheartdan]

Me: *watches this video to learn*


Me: *ends up questioning my own existence* Thank you Vsauce, very cool.

3:56 "... let's say this distance is a light second."

Those are some big ass spaceships then lmao.

[paradox]

Tbh, this is one of my favourite vsauce videos of all time, it contains so much information and ideas that literally bend my brain.

I can't walk to my refrigerator if it's always running
