What if the universe had a higher dimensional twist in it?

Me: "Ahh finally -- some direction in my life"

Zach: "Hold up there bucko"

I saw this title and thought damn Zach really goin crazy during quarantine

[DanteKG.]

0:37 "But what if it weren't?"
Hey Zach Star, Zach here...

[RCSmiths]

I know I'm not the only one who stupidly and immediately thought, "This was my right"

"No Zach, that's your left". Haha. Awesome work as always!

A rare example of an electrical engineering student who actually enjoyed physics 3

Last time I was this early the channel name was still MajorPrep

[ryanvsiler]

Zach, I have recently found your channel, I have aphantasia which leaves me unable to visualize or use any senses in my imagination and I always had a hard time with math. I've been studying a lot of math and physics to get a better understanding and topology has really started to interest me especially, thank you for giving some in person visualizations for those that cannot imagine what you're saying! Thank you!

I feel like we are watching Major Prep shift from an engineer to a theoretical physicist/mathematician and I'm all for it.

I thought this was going to be about the 3 directions/dimensions really existing, but I have to say this is an equally great topic.

Great Content as always. This guy never disappoints😁

[geniegerny]

Love how it started with confusing left and right and ended with curvature of spacetime :D ^^

Nah, one strange idea: the guy returns being "inverted" and cannot even eat some things, if I understand correctly. Since life on Earth can only uses one version of proteins from the two possible ("left" and "right") versions. But I'm curious that besides of the biological issues, are there any other "problems" he would experience to be able to exist? Like things, weak force (IIRC ...) seems to care about right/left symmetry though not other forces (however I have no idea if it causes problem for a living being when "inverted"). Again, if I'm correct with these, just guessing what would happen.

[lukereed]

For the hypothetical twin who travels and gets inverted, I assume from his perspective once he completes the trip around, he wouldn't view himself as having changed at all, but instead would see me as being inverted? Is that correct?

Higher dimensional being: *twists the universe*
People who just found their way again after being lost: “Ah shit, here we go again”

Does directions really exist?




*Vsauce music plays*

[dexterjettster]

Does direction exist?
Not in my life.

[evergreen]

I thought you were going to demonstrate the intrinsic curvature without the need for a higher dimension. I missed that part.

Sat nav: On 24th street turn right
Zack star: Yeah, but, is there really direction
Sat nav: *confused screaming*

12:30 I don’t know what it was about that pen throw but it was awesome

Or what you get when you give Cliff Stoll currency. Good man.
