We know that Schwarzchild metric describes an asymptotically flat spacetime. This means that far away from the event horizon we can safely interpret the ##r## coordinate as distance from the center.(adsbygoogle = window.adsbygoogle || []).push({});

But when close enough to the event horizon the curvature becomes significant and our common sense of ##r## breaks.

The question is that what is understood as measurement of the coordinates near very strong gravity?
