After years with Michael, the thing that takes him away was what we least expected. The TheXvid corporate soul consuming machine known as "premium." It's enough that I get an ad for almost every video but now I can't even watch fucking Vsauce. FUCK YOU TheXvid, YOU WERE ONCE SO SOULFUL AND UNIQUE.

Welp, I guess the flat-earthers were right about one thing... gravity doesn't exist.

• KILLEr 2 days ago

0:41 it's actually because the earth is an magnet and if you ever whatched the film cartoon called The Ice Age in one part of the film there's that animal what is trying to get to its nut and for some reason falls in a deep hole which gets him to a big gray ball. So that's the magnet which means at that magnet is very hot and the gravity is going to get you down when jumped in about 0,57 seconds while at the ground will take atleast the double amount. Thanks for reading, hope you learned something from this comment and wear your seatbels

The earth is actually flat.Whenever we drop things it’s just that the earth is moving up to meet the falling object.

Nope, didn't get a bit of it. If we stay with the pencil-on-the-cone demonstration, why would the pencil start moving? I didn't hear one bit of explanation on that.

• Moonlight io 2 days ago +1

wait... which way is down? if i'm on the other side of the earth, than my down is up. if i'm on the side of the earth, my down is sideways, which means down is every direction, which means everything i've been taught is a lie.
that means that my entire life i've been lied to and i am living a lie.

what is a day? if you're in space, then you won't experience any change. if you're on earth, then you'll experience a change in time, which means that there would technically be no such thing as a day if the solar system didn't exist, since other planets experience days too, then there would technically be no such thing as time since there is nothing there to tell how long you have been there. i have been lied to.

sorry i think a lot xD

It's not the difference in the flow of time between your head and feet that causes falling. If it where, you'd fall slower when lying down than when standing.

Hey Vsauce Michael here what is a person. Well its a simple awnser that can get very complicated. ”vsauce music plays” then he goes off and explains what a human is but then he says but if you were a cat and saw another cat would you say that other cat was a person after that he goes off into the creation of the world and the start of life on earth and in the end we come to the decision that a person is made up of crazy space ingredients. The End

Michael, we miss VSauce.
I loved how you covered humane sciences, linguistics, physics, mathematics and much more, it was beautiful, it was entertaining, it was FUN
I only saw the free videos from Mindfield and I must say: despite the quality and effort that you always put in your projects, the free VSauce videos were waaaaaaaaay more interesting because it was unique
Don't get me wrong, you have made an excellent job at Mindfield, but it ends up following the same old format that we were sick of (although the themes are super nice). Do you know what I mean? VSauce was unique, it was crazy, it was Michael talking to the public, there was a connection that was lost in Mindfield (which should be on a completely different channel btw)
AND I FRIGGIN MISS THE VSAUCE BACKGROUND MUSIC :'(
pls come back :'(
