Is clock syncrhronization actually important to your question? It's not obvious to me why it's relevant to your problem, and it'd be a... -
I have a very naive question? How do we know with 100% certainty that the inside of a blackhole is s singularity? I mean nobody has...

Bosko replied to the thread A A global energy conservation law in general relativity.I think that the answer is in the Noether's theorem. That question appears in the early stage after Einstein published the GR theory...

Informative.
There is no object at all in the Schwarzschild spacetime. It is a vacuum solution. The assumptions are spherical symmetry of the... -

Like.
For ##r < r_s##, the coordinate ##r## is timelike. Just because you use ##r## as a coordinate doesn't mean it's a radius. The... -
Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.Do you think that for ##r_1 < r_s## the mathematical model does not correctly represent physical reality?

Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.Two objects of the same mass but different radii.

Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.Thanks. I put the topic in "Beyond the Standard Models" so as not to violate the forum rules in case someone offers non-standard thinking.
-
Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.That's exactly what I thought. Edit: That is valid
-
Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.In other words, for any ##r_1## and ##r_2## the solution is the same outside of ##max(r_1,r_2)##. Am I right, even if one of ##r_1## or...

No it isn’t. The usual derivation starts by assuming spherical symmetry and a vacuum solution and then proceeds to solve the EFEs under...
-
Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.There is no parameter of a spherically symmetric object in the solution. For example, the radius . The solution does not depend on the...
-
Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.It might be better to ask an equivalent question: Let two spherically symmetric objects of the same mass of radius ##r_1 \lt r_2## be...
-
Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.Any. Some are explicit with the point mass as the represent of the spherically symmetric object and other are using the equivalent...

Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.The first part can be derived from the second part . E.g. The array of shells with the same mass and with 1/n radius . By subtracting...
