Universal Law of Gravitation
Sir Isaac Newton published this law in a three volume work known as the Principia. A century later, two scientists to apply Newton's Laws of gravity to calculate that a star of sufficient size and density could prevent light from leaving its surface, creating a 'dark star' "Timeline of Black Holes through History, Newton to the Present - Black Holes Encyclopedia."

John Michells Dark Stars
John Michell suggested that the surface of gravity of some stars could be so strong that not even light could escape from them. He even calculates that a dark star would be just a few miles in diamater. "Timeline of Black Holes through History, Newton to the Present - Black Holes Encyclopedia."

Gravitational Drain
Roy Kerr told us that black holes will 'drag' the space time around them, like a whirl pool or gravataional drain.

Eventual Evaporation.
Stephan Hawking shows that black holes may not even be black. They might produce a form of radiation that will eventually have them to evaporate.

Galaxy or Black Hole?
Astronamers discovered that the creation of super massive black holes in the centuries of galaxies seems to be connected to the creation of the galaxies of themselves.

Aprroaching a Black Hole
At the center of the Milky way there is a blck hole which is slowly being approached by a massive cloud of dust and gas, which is three times larger than the mass of Earth.

Black Holes Never Die
Old black holes never die, they just fade away. George Ellis of the University of Cape Town in South Africa said, He also suggests that the cosmos may be littered with an untold number of shrunken black hole remnants. Cowen, Ron.

Monster Black Holes
When they draw in material from their surroundings, such monster black holes can shoot out jets of energetic particles that stretch for hundreds of thousands of light-years, as in the galaxy Hercules A. Hlavacek-Larrondo, Julie. "On the trail of monster black holes: collapsed objects weighing millions or billions of times as much as the Sun lie at the heart of nearly all galaxies. New images are finally stripping the mystery from these spheres of warped space." American Scientist 101.6 (2013): -
Albert Einstein's Theory
Predictions about the existence of black holes date back nearly a century to Albert Einstein's theory of relativity. In 1915 one of Einstein's colleagues, Karl Schwartzchild, showed that a sufficiently massive object could curve space and time in on itself, cutting itself off from the rest of the universe. Hlavacek-Larrondo, Julie. "On the trail of monster black holes: collapsed objects weighing millions or billions of times as much as the Sun lie at the heart of nearly all galaxies. New ima
