1, Singularity Theorem: Completed the shortcomings of Einstein's general theory of relativity. By using the method of topology, it is proved that the general relativity equation will lead to odd point solutions, which indirectly proves the existence of the big bang singularity. Einstein previously denied the existence of singularity, and even wrote a paper to demonstrate its impossibility.
2. Hawking radiation: 1974 Hawking published "Will a black hole explode?" Articles ". This is the greatest paper on gravitational physics in the 20th century after Einstein. In this paper, he introduced the quantum theory effect into the study of black holes, and proved that all kinds of particles will evaporate near the horizon of black holes, and the spectra of such particles are like radiation from blackbodies. As the mass of the black hole decreases, the temperature will increase, which will eventually lead to the explosion of the black hole.
When it comes to black holes in the universe, Hawking is definitely an unavoidable hero. In addition to his superb academic attainments, Hawking has set an example for future generations in the dissemination and encouragement of popular science by virtue of his global popularity and strong fighting spirit.
4. Academic contribution: With the help of singularity theorem and Hawking radiation, Hawking put forward the borderless universe theory. For the first time, I tried to explain the beginning of time and the origin of the universe from the perspective of science rather than theology, and completely excluded God from the creation of the universe for the first time. It directly proves that the myth of "the first push" invented by Aristotle, Augustine, Newton and others in the universe for God is completely false.
5. Interstellar Migration Hypothesis: As early as 20 1 1, Hawking said in an interview with American video website BigThink that the earth will be destroyed within 200 years, and human beings can only emigrate to other planets if they want to survive. He predicted that by 2600, the world will be very crowded, and electricity consumption will turn the earth into a "hot" fireball. The best way to avoid the end of the world is to emigrate to space and explore the possibility of human life on other planets.
