Time is a human concept for expressing change perceived from our
subjective perspective.
How the heck the Block view of Time got so damn popular I'll
never know, except it's easy to graph.
Oh look, we twist and warp the paper the lines are drawn on and
go up a dimension. Ooh, spooky.
Still a block. Just jello instead of a wooden cube.
it's a useful abstraction and turns spacetime into a cake that
easy to slice and analogize to mathematical form as well...
but... it's a block. Objective "outside the Universe"
perspective.
Useful, but not enough ultimately.
