Einstein's theory of general relativity from 1915 predicted the possibility of black holes, but they were not believed to exist until convincing evidence was found in the 1970s. Black holes are incredibly dense regions formed after massive stars collapse, where gravity is so strong that not even light can escape. They can be stellar-mass, supermassive, or mid-mass depending on their origin and size, with supermassive black holes found at the centers of many galaxies including the Milky Way.

BLACK HOLES Title
1915: Einsteins Theory of Gravity predicted the possibility of black holes, but no one believed they actually existed! 1967: Term Black Hole coined 1970s: Convincing evidence that black holes are real Today: NASA space telescopes have discovered evidence for black holes throughout the universe Albert Einstein
What did Einstein say about Gravity? Mass distorts space - curving it Objects and light moving near the massive object are forced to take a curved path around the object. Just like the Moon orbiting Earth.
What is a Black Hole? An unimaginably dense region of space where space is curved around it so completely and gravity becomes so strong that nothing, not even light, can escape. Mass is so great in such a small volume that the velocity needed to escape is greater than the speed light travels.
How much would you weigh? On Earth, lets say you weigh 150 lbs. On the Moon, youd weigh 25 lbs. On Jupiter, youd weigh 350 lbs. On the Sun, youd weigh 4,000 lbs. Near a Black Hole, youd weigh over 20 TRILLON POUNDS !!!
There are 200 billion stars in our galaxy, the Milky Way There are also millions of black holes Including one giant black hole at the very center.
Where do black holes come from? Three classifications of black holes: Stellar-mass: 3 to 20 times the mass of our Sun Supermassive: Black holes with millions to billions of times the mass of our Sun Mid-mass: In between stellar-mass and supermassive
Stellar-mass: Black holes are made when a giant star, many times the mass of our Sun, dies. Most of the stars atmosphere is blown into space as a supernova explosion. The stars spent core collapses under its own weight. If the remaining mass is more than the mass of 3 Suns, it will collapse into a black hole. Where do black holes come from?
Supermassive: Extremely massive black holes have been found in the centers of many galaxies - including our own! Where do black holes come from?
Mid-Mass: Scientists are finding these in the centers of large, dense star clusters. Like this globular star cluster, called M15, in our Galaxy. Where do black holes come from?
