Shining a light on a black hole

Research from the Moscow Institute of Physics and Technology (MIPT) (1) hypothesizes a measurable and elegant difference between a black hole and a compact object. The event horizon of the black hole, defined by the Schwarzschild radius, is significant - anything slightly bigger shows fundamental differences in behavior. A beam of scattered particles shows discrete spectra in the presence of a compact object that escaped collapsing into a black hole. If it were a black hole, it will be in a constant process of collapse, with a complete stoppage of time for an external observer, resulting in a continuous and smooth spectra.

The concept of a black hole has been an enigmatic thought experiment for physicists and amateurs alike. Contemporary theory fails in the singularity and speculates a stoppage of time inside the event horizon, something that cannot be fully envisioned by humans trained in the practical regime of Newtonian Mechanics. A black hole will never stop collapsing from an external perspective and so there cannot be any ex.post question on a black hole. Theories that attempt more detailed explanation beyond the event horizon is fantasy - just as the mathematically elegant string theory that cannot be tested. In spite of all the engineering progress in the last hundred years, fundamental understanding has remained akin to a black hole - in suspended animation. A handful of men and women from the turn of last century remain to be responsible for most of the abstract knowledge that humans have accumulated. The reasons for this is unclear but lack of imagination appears to be the prime suspect.

Fooling around with mathematics may give contemporary scientists satisfaction but explaining the stoppage of time will require more than that.
