Consider a spherical symmetric mass distribution in space, located around the origin of a coordinate system. One can forumlate a stress-energy-tensor $T^{\mu,\nu}$ for this situation. Solving the Einstein-field-equations for a reference frame, in which that mass distribution is not moving one obtains the Schwarzschild-metric $g_{\mu,\nu}$. One can now try ...

m includes all kinds of energies for the mass at rest, including the thermal energy, and those from the other degrees of freedom, such as the ones internal to the nucleus, as AnnaV mentioned. So you only have to compute mc^2, the HTM term is redundant.

rob's answer already touches on your misconception that quantum entanglement by itself could be used to send information. From an engineering point of view, the problems are even more basic: In order for Alice and Bob to create an entangled state, we must first choose a quantum system. For convenience, let's use the polarization of photons, i.e. an ...

Quantum entanglement doesn't transmit information. When you have two experimenters (usually called Alice and Bob, because real people aren't named A and B) doing widely-separated experiments on entangled particles, each of them does a separate experiment on each particle. For example if the entangled particles are photons with opposite polarizations, each ...

Given an unsharp image, you can use deconvolution to attempt to reconstruct the original image, but the resolution you obtain will be limited by the noise in the unsharp image. The theoretical limit for the case of astronomical images where the objective is to resolve double stars, is investigated in this paper.

No, because you have no information on how far objects are, and that affects the spread of the light. If you were taking the photograph of a 2D plane (a painting for example), you probably could retrieve more information, but it would still have a considerable quality loss, since in the borders you don't have the entire spread, some would be out of the ...
