Searches for Black Holes. the Most Recent Results

TL;DR

This paper reviews recent observational efforts and theoretical considerations regarding black holes, highlighting the ongoing search and the evidence supporting their existence as predicted by Einstein's General Relativity.

Contribution

It summarizes recent observational results and discusses upcoming experiments aimed at confirming the existence of black holes in the universe.

Findings

Hundreds of compact objects observed with properties similar to black holes

Upcoming experiments planned to test black hole existence

Theoretical models vary on black hole predictions

Abstract

Black holes were predicted by Einstein General Relativity (GR). Because of unusual properties of these objects their existence is almost unbelievable. There are gravitation theories which do not predict the black hole appearance. By now, astronomers discovered a few hundreds of massive and highly compact objects with observational features which are very similar to the properties of black holes predicted by GR. To confirm existence of black holes in the Universe, a number of groundbased and space experiments are planned to be held in the coming decade.
