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.
