u go faster(run hihg sped) maek go slower(time)

Dont run too fast or your wifu will age faster than you

This is only special relativity not gr. The trampoline analogy is ok for this.

Local Lorentz covariance

It provides a model for how the intrinsic distance between points in space (and time) is determined by pressure/energy densities in said space.

Intrinsic here means how the distances look within that space, e.g. if you walk on the surface or inside the volume - e.g. the poles of a unit sphere (pic related) are instrinsically pi unit steps (a half-circle) away from each other. Externally, he may say that the poles are only 2 unit steps away, but this "go though the ball" path is not part of what we look here.

The matter infleunced distances in out R^3 (or R^4, if you add time) can be played with in a way that e.g. you can drop the Newtonian 1/r^2 force completely, you can replace gravity buy a model that says things approach each other because their natual paths are such that their distances between them just shrink in stance over time.
The effect of 1/r^2 "force" is just an aspect of the metric/distance function.

It's all relative, man.

Maybe even some cheat codes for it that we've found out.

Space and time are actually two aspects of a single, unified space-time structure, and time isn't constant but instead relative to matter and energy.
