1, Singularity Theorem: This proves the incompleteness of general relativity with roger penrose. They pointed out that if general relativity is generally established, then there must be some singularity in the space-time of the universe. By using the method of topology, it is proved that the general relativity equation leads to the odd point solution, which indirectly proves the existence of the big bang singularity.
2. Black hole theory: Inspired by Beckenstein entropy, under the background of curved space-time, it is proved by quantum field theory that black holes radiate like thermodynamic blackbodies. It is proved that all kinds of particles will evaporate near the event horizon of a black hole, and the spectrum of such particles is like radiation from a black body. As the mass of the black hole decreases, the temperature will increase, which will eventually lead to the explosion of the black hole.
3. Boundless Universe Theory: Boundless theory of quantum cosmology is established. He believes that time and space are finite and unbounded, and the universe is not only self-consistent, but also self-sufficient. It doesn't need God's first push at the beginning of the universe. The evolution and even creation of the universe are determined by the laws of physics alone.
Extended data stephen william hawking (1942 65438+1October 8th to 20th1March 8th14th), male, was born in Oxford, England, a famous physicist at Cambridge University, one of the greatest physicists in modern times and one of the great men with international reputation in the 20th century.
1963 Hawking suffered from amyotrophic lateral sclerosis (Luger's disease) at the age of 2 1 year. He is completely paralyzed, unable to speak, and only three fingers can move in his hand.
1979 served as Lucas professor of mathematics from 2009 to 2009. His main research fields are cosmology and black holes. He proved the singularity theorem and the black hole area theorem of general relativity, put forward the black hole evaporation theory and the borderless Hawking universe model, and took an important step to unify the two basic theories of physics in the 20th century-Einstein's theory of relativity and Planck's theory of quantum mechanics.
He was awarded the honors of CH (Lord Honorary of England), CBE (Commander of the British Empire), FRS (Member of the Royal Society) and FRSA (Member of the Royal Art Association).
20 12 On April 6th, the hit American TV series "The Big Bang Theory" aired in episode 2 1 of the fifth season, in which stephen hawking made a guest appearance. 20 17 recorded the documentary "exploring a new earth" for the British BBC.
Physicist Stephen Hawking165438+1October 6 said that technology is expected to reverse some hazards brought by industrialization and help eliminate diseases and poverty, but artificial intelligence needs to be controlled. 20 17, 165438 10, Hawking predicted that energy consumption would increase in 2600 and the earth would become a "fireball".
On March 20 18 14, Hawking died at the age of 76. After Hawking's death, it has aroused condolences from all walks of life around the world.
