STEPHEN HAWKING

Stephen Hawking. He is one of the mathematical physicists and inventor of the theory of black hole and quantum gravity. Hawking was born on 8 January 1942 in Oxford; from Dr. couple. Frank Hawking, a biologist, and Isobel Hawking. He has two siblings, and a brother of adobsi. Hawkin died on March 14, 2018 in England.

When he was older, Hawking liked to study physics rather than biology like his father. when Hawking studied at Cambridge University, Hawking suffered from Amyotrophic Lateral Sclerosis (ALS) which made him paralyzed. Soon Hawking suffered from pneumonia so he could not speak at all. After that, there was a Cambridge scientist who created a tool that could make Hawking write what he wanted to say on the computer, then pronounced through a 'sound synthesizer'. This is the tool that Stephen Hawking used throughout his life.

After that, Hawking discovers the theory of black holes. Hawking states that the entry into the black hole will disappear with the loss of a black hole. He discovered the Black Hole theory in astronomical systems, the universe region. Black holes arise when a large and dense star in a supernova. The gravitational force pulls out the outer layers of the star to go in the direction of the black hole core. The collapse of the force of gravity makes almost no light can escape and none of that surface escapes. So Stepshen Hawking says that the black hole is the entrance to another world.

            So, stephen hawking is a great physics scientist who created the theory of black hole along with the theory of quantum gravity despite suffering Amyotrophic Lateral Sclerosis (ALS) . We can see the struggle of stephen hawking by keep trying in any condition.
