If you rotate the universe so some spatial axis be on the time

>>8532986
Time and space are inseparable, not interchangeable.

>>8532986
Don't you mean, WHEN would the universe look like?

Axes are arbitrary distinctions we've made to understand relationships between various points. This is like asking what would happen if you place the "z" axis where the "x" axis was and the "x" where the "z" was. Absolutely nothing. Nothing has changed about the function because you've changed the coordinate system you're using to understand that function visually. Given, a time dimension, at least in Minkowksi Spacetime, is not treated in the same manner that a spatial dimension on a Cartesian coordinate system would be,but it's regardless.

Which is *WHY* relativity is bullshit.

bampin.

Hahahaha nice one

My favorite usages of that joke in media are from Family Guy and Gravity Falls

This kind of rotation is an orthogonal transformation but not a Lorentz transformation, so some signs would change.

You should clarify what function does each axis receive now.
Lets change the Z axis for the time axis.
That means the Z value will forever increase in value while all the time and X and Y represent what we perceive as space.
Well, depending on which Z value are we in, the universe would look like a piece of abstract art.
For example: suppose a square perfectly parallel with the XY plane appears expands and shrinks and then dissappears while in normal space.
Well in Z-time space if you chose the point of Z where the square appeared, you would see a vertical diamond (like two four sided pyramids stuck together by their square bases and their points pointing up and down) with its lower point representing its appearance, the broading being the expansion, and the top point its dissapearence.
If the Z value moves just a little, you stop seeing anything at all in this universe, because the square doesn't exist in other point of Z even if it exists in normal time for a while.
