Even the Minkowski space is holed
S. Krasnikov
To cure the lack of predictive power of general relativity Geroch proposed to complete the theory with an additional postulate that only "hole-free" spacetimes are permitted. I arg…
Falling into the Schwarzschild black hole. Important details
S. Krasnikov
The Schwarzschild space is one of the best studied spacetimes and its exhaustive considerations are easily accessible. Nevertheless, by some reasons it is still surrounded by a lot…
Unconventional string-like singularities in flat spacetime
S. Krasnikov
The conical singularity in flat spacetime is mostly known as a model of the cosmic string or the wedge disclination in solids. Its another, equally important, function is to be a r…
Superluminal motion in (semi)classical relativity
S. Krasnikov
The possibility is discussed of superluminal motion of non-tachyonic (i.e. moving with the instantaneous speed v<c) bodies within general relativity. It is shown that in some occas…
