A thin dust shell falling to a Reissner-Nordström black hole as seen by a freely falling observer

Abstract

We study the observation of a thin dust shell, radially freely falling to a Reissner-Nordström black hole, by an observer who is also freely and radially falling into this black hole. Considered and resolved are several common paradoxes and fallacies peculiar for such problems. The results of this analytical study are written as a numerical code that allows for calculating all related effects of this model. The numerical result have been presented in a few synthesized videos, making a colorful, quantitative and detailed description of the occurring astrophysical phenomena, both above and below the horizon.
