Bringing the Universe Down to Earth: In Memory of Stephen Hawking – World Renowned Scientist:
“He once said: ‘It would not be much of a universe if it wasn’t home to the people you love.’ We will miss him forever.”
Stephen Hawking is a world-renowned theoretical physicist, known for his contributions to the fields of cosmology, general relativity, and quantum gravity, especially in the context of black holes. Stephen Hawking has died at the age of 76. Scientists, politicians and actors have paid tribute to world-renowned physicist Stephen Hawking, who has been called an “inspiration to millions”. Let’s have a look at What has Stephen Hawking done for science.
Dr. Stephen Hawking Achievements in Science:
1971-72 Black hole mechanics:
The Famous Black hole theory is also known as the Hawking area theorem. Hawking came up with the second law, which states that the total surface area of a black hole will never get smaller, at least so far as classical (as opposed to quantum) physics is concerned. The law implied that black holes were warm, a contradiction of classical physics that stated black holes could not radiate heat. In separate paintings, Hawking labored on the “no hair” theorem of black holes, which states that black holes can be characterized by way of three numbers – their mass, angular momentum, and charge. The hair in question is different statistics that vanishes whilst it falls into the black hole.
1974-75 How black holes can vanish:
Hawking drew on quantum theory to reveal that black holes have to emit warmness and eventually vanish.
The technique is slow for everyday black holes. It would take longer than the age of the universe for a black hole with the equal mass as our solar to evaporate. But smaller black holes evaporate faster, and close to the give up of their lives launch heat at an impressive charge. In the closing tenth of a 2d, a black hole should explode with the power of a million one-megaton hydrogen bombs.
1983 Wave function of the universe:
Hawking has spent lots of his time looking to expand a quantum principle of gravity. He started out making use of his idea of Euclidean quantum gravity to black holes, however in 1983 teamed up with Jim Hartle at Chicago University. Together they proposed a “wave function of the universe” that, in theory, will be used to calculate the residences of the universe we see around us.
- Hawking wrote the famous book A Brief History of Time
- He also authored several other popular books popular including Black Holes and Baby Universes.
- He received numerous awards including the Gold Medal of the RAS.
- Hawking ranked as one of the 100 Greatest Britons in a BBC poll.
