Black Hole
Black holes are part of galaxies that have extremely powerful gravitational fields from what after crossing the event horizon even electromagnetic radiation, for example simple visible light, cannot escape. Black holes have invisible interior, but nevertheless are observable by telescopes due to reactions with matter that has an orbit outside of the hole’s event horizon. For example, a group of stars can orbit around the center of a black hole, in which case often gas from a nearby star is drawn into the black hole where it, while spiraling inwards, heats up and starts to emit radiation that is visible by telescopes.
Scientists started to talk about objects in space with huge gravity force in the end of the 18th century. The concept of these holes is explained by the general theory of relativity, according to what due to a large enough mass is in a sufficiently small region of space, all the paths in space are misshaped inwards to the center of that mass, due to which no matter or radiation can escape. Scientists who take the effect of quantum mechanics into account believe that black holes do not hold the matter they have captured forever, but start to leak so called Hawking radiation and may not be infinitive. However, scientists are still working on trying to prove this theory.
