Different abstraction level. Evolution provides a framework for biology which works at every level. EX: Why does the human optic nerve cause a blind spot? At the detail level biology is filled with a huge range of less than optimal solutions, but when 'it worked' is the only limitation things click.

Physics has a lot of data and several models that work really well, but they don't really fit into a single coherent system. QM vs Relativity etc. The density needed to form a black hole decreases linearly with radius, sho why is the universe not one?

I feel like this explains it pretty well.

tl;dr: Schwarzschild’s solution is a static one, meaning that the metric of space does not evolve as time progresses.
