When matter falls into supermassive black holes in the centers of galaxies, it unleashes enormous amounts of energy and is called an active galactic nuclei (or AGN). A fraction of AGN release part of this energy as jets that ...

A group of researchers at Sofia University has found evidence that suggests the reason that a wormhole has never been observed is that they appear almost identical to black holes.
The fine structure constant is one of the most important natural constants of all. At TU Wien, a remarkable way of measuring it has been found—it shows up as a rotation angle.
