Everything that can happen in the universe has already occurred.

This is the block universe theory in physics.
From this perspective,
the past, present, and future are not flowing,
but are like a solid crystal,
quietly embedded in spacetime.
Destiny is not simply linear determinism,
but rather all possible futures
are already "etched" into spacetime like data.
Just like a game disc,
which ending you get depends on you.
