@joshwhatdahale In general relativity spacetime is a non-uniform 4 dimensional manifold, but it's sort of nonsensical to refer to them as '3rd, 4th, 5th'; if you hold a cube in your hands, which comes first; it's height, width, or its depth? It really doesn't matter since you can rotate it 90 degrees in any direction and thus swap 2 of its dimensions. Same goes for spacetime.
@RenegadePhilosopher so the 4th spatial is the 5th in general relativity. And the 5th dimension of general relativity is time travel, right? Or more or less having a view of our entire existence as one point, kinda? Im just starting to study this stuff. I think its very interesting
@junior1984able sorry. but you're a fucking idiot. we live in every dimension. that's the point of a universe... the "4th" dimension is time. space is the separation of objects and time is the separation of events. a "tesseract" is a cube inside a cube with the corners of one attached to the corners of the other. and every angle is a 90 degrees. that's a 4 dimensional object.
sir, you are 5 years older than me, and im high as fuck. but you're still a fucking idiot.
Okay most of you are unbearably stupid: There is a DIFFERENCE between the 4th dimension in the sense of general relativity and the fourth SPATIAL dimension. In physics, the fourth spatial dimension is considered the 5th dimension. This video concerns the 4th spatial dimension, which has absolutely nothing to do with time. The 4th dimension according to general relativity is duration, the 4th spatial dimension doesn't have anything to do with duration, or temporality, it is spatial.
Thank you, this described 4d better than that video explaining it with words :)

There are quite a few of these representations floating around, anyone know if they are mathematically accurate or just 'artists renditions'?

@ThatsTooSmall how could anyone know what a 4rth dimesnion is really like genius! Sorry, do you live in it!?
