Web13 Mar 2016 · 4 Answers Sorted by: 10 Coordinates can be measured in GR, though all too often this fact is overlooked or even contradicted by people getting caught up in coordinate invariance. As you well note, in Schwarzschild $r$ isn't really a radius in the "integrate at constant angle from the center and recover this value" sense. WebEven if the mass is pulsating (remaining at mass M but its radius may be changing), the exterior metric remains static. This tells us that spherically symmetric bodies can not …
