Stephen Hawkin
Stephen Hawking did.
That most likely refers to Stephen Hawking.
They are studied by astrophysicists which is a branch of astronomy dealing especially with the behavior, physical properties, and dynamic processes of celestial objects and phenomena.
He explained the Laws of Motion which govern movement from subatomic particles to black holes; as well as the Universal Law of Gravitation.He explained the Laws of Motion which govern movement from subatomic particles to black holes; as well as the Universal Law of Gravitation.He explained the Laws of Motion which govern movement from subatomic particles to black holes; as well as the Universal Law of Gravitation.He explained the Laws of Motion which govern movement from subatomic particles to black holes; as well as the Universal Law of Gravitation.
Black holes and subatomic particles are a subject of interest in the fields of astronomy, astrophysics, and particle physics. Perhaps the most famous to bring to light the notion that black holes could emit particle/antiparticle pairs and thus lose mass through loss of energy would be Professor Stephen Hawking, who proposed that black holes interact with the universe thermodynamically in this way and could potentially evaporate entirely. This radiation is often referred to as Hawking radiation.
The extent of gravity near a black hole is terriifically huge - so huge that even particles of light are drawn into it. If the light particles are drawn into the black hole, they obviously cannot radiate outward so that we could see them.

Only black holes and subatomic particles remain. The universe has expanded so much that these individual particles may be separated from each other by truly enormous distances. Black holes themselves are now evaporating by Hawking radiation.
The discovery of black holes was not due to a single person; several people participated, and at first, it was all very theoretical. You can find some of the history behind the theories and discoveries in the Wikipedia article on "Black hole".
When an atom is smashed in a black hole, its particles are torn apart due to the extreme gravitational forces. The subatomic particles are then absorbed into the black hole, adding to its mass and energy. The energy released during this process can contribute to the black hole's growth and power its intense gravitational pull.

Because black holes are of such density that even light can no escape them, they don't radiate any light and are black.
