Line element ds in the Schwarzschild metric(describing spacetime around
a massive object like the Sun):

ds² = -(1 - 2GM/c² r) c² dt² + 1/(1 - 2GM/c² r) dr² + r² dɸ²


Why, to approximate a solution, dt=0 (spacelike event)?

This sure makes ds² > 0.

Have any answer, amateur expert relativist?

I'm waiting for your display of wisdom, Paul.
