The Theory of Gravity
In 1687 Newton published his book titled the Philosophiæ Naturalis Principia Mathematica which, in english, means the Mathimatical Principles of Natural Philosophy. This book described Newton's theory of gravity.

The First Concept
In 1783 John Michell thought up an object with such an enormous mass the it would be impossible for even light to escape. -
Existance of Black Holes Predicted
Pierre Simon Laplace published his Nebular Theory which presented the possibility of massive stars whose immense gravity would not allow light to escape, now known as black holes. (Note: Not exact date) -
General Theory of Relativity
Albert Einstein's General Theory of Relativity describes what happens to particles as they accelerate. This theory affects black holes because the particles that heat up the outer disk to make a bright circle. Also explains how light can be affected by gravity. -
The Discovery of White Dwarfs
Subrahmanyan Chandrasekhar exposed the theory that determined, depending on a stars mass, if, when it dies, the star will become a white dwarf, neutron star, or a black hole.

Space Time Being Pulled Down
Roy Kerr discovered that black holes pull down on the fabric of space time and create a swirling vortex. (note not exact date) -
Black Hole Variants
Maartan Schmidt discvoered the Quasar, and the fact that every Quasar is actually energized by what is at every galaxy; a supermassive black hole. (note not exact date) -
Cygnus x-1
The current star Cygnus x-1 was discoverd to have an extraordinary mass and is realeasing immense ammount of x-rays, making it the most likely black hole candidate. -
Term "Black Hole" Was Coined
During an interview in 1967, John Wheeler used the term "Black Hole" to describe an object whose mass was so great that even light could not escape. (Note: not exact date) -
Pulsating Radio Waves
Jocellyn Bell discovered that there were certain things in the universe that emitted regular radio waves. (note not exact date) -
Stephen Hawking Develops Modern Thoery of Black Holes
Hawking theorized that black holes are radioactive and that they give off radiation until all their energy dissapates. (Note: Not exact date) -
Black Holes are Like Spinning Tops
It was discovered that black holes had an axis of symmetry

Rotating Not Pulsating
After a star collapses the gravity calms down and to a rotatiion not pulsating
(note not an exact date) -
Black Holes and Evaporation?
Stephan Hawking discovered that black holes did not live forever because the radiation that they throw out will eventually cause the black hole to decay. -
Supermassive Black Holes Are Like Glue
We learned that at the heart of every galaxy is a supermassive black hole, and that the suppermassive black hole is holding everything around it in orbit! Without supermassive black holes galaxies would never had existed, or they would have been much smaller. (note not exact date)
