Black holes are the cold remnants of former stars. They are so dense that no matter -not even light - is able to escape their powerful gravitational pull. These are interesting objects from a fundamental physics point of view and play an important role in astrophysics.

Physicists are still seeking a full, consistent quantum theory of gravity to describe black holes. a “black star” instead. A black hole is a region of curved spacetime with such intense gravity that noth-ing can escape. Its defining feature is its event horizon: the boundary of the region of no escape.
stars are the true rock stars of the uni-verse: They shine bright, live fast, and die young. Defined as stars with masses a hundred times or more than that of our Sun, these stars can be...
