Learn about the Schwarzschild radius as it pertains to black holes. Topics include the event horizon of a black hole and how Einstein used the...
It is shown explicitly that a new interior Schwarzschild solution satisfies a set of necessary and sufficient conditions for a spherically symmetric metric to join smoothly onto the vacuum field at a nonnull boundary surface. Moreover, the conditions do not prevent the radius of a spherical ...
Simple charged particle model has limited validity in description of matter around BH – one should assume low particle density, i.e., that the mean time of two particle interaction is longer than orbital time around BH. One should also note that the typical Larmor radius of a particle in ...

In general relativity the amplitude of the perturbation is dominated by high velocity effects, which grow linearly in the radius $r$ of the circular orbit, while the leading term surviving the Newtonian limit decays as $1/r$. Thus even for very large radii a significant difference between ...

This equation is very general and applicable even at the astrophysical level, provided the restrictions on the mass and the radius of the astrophysical objects of interest, as mentioned above, are satisfied. On the other hand, for not too strong magnetic fields, like those used in tabletop expe...
