Hawking's profile:

Hawking's original name was Stephen William Hawking. He was born in Oxford, England on January 8, 1942. In 1963, Hawking suffered from amyotrophic side effects at the age of 21. Thoracic sclerosis, paralysis of the whole body, unable to speak, and only three fingers on the hand can move.

He served as Lucas Professor of Mathematics from 1979 to 2009. His main research areas were cosmology and black holes. He proved the singularity theorem and the black hole area theorem of general relativity, and proposed the black hole evaporation theory and the boundaryless Hawking. The universe model has taken an important step in unifying the two basic theories of physics in the 20th century, the theory of relativity founded by Einstein and the quantum mechanics founded by Planck.

In the 21st episode of the fifth season of the popular American drama "The Big Bang Theory", which was broadcast on April 6, 2012, Stephen Hawking appeared in his true form and participated in a guest appearance. In 2017, he recorded the documentary "Exploring the New Earth" for the British BBC. Physicist Stephen Hawking said on November 6 that technology is expected to reverse some of the harm caused by industrialization to the earth and help eliminate disease and poverty, but artificial intelligence needs to be controlled. In November 2017, Hawking predicted that in the year 2600, energy consumption will increase and the earth may become a fireball. Hawking passed away on March 14, 2018, at the age of 76.

Extended information:

On January 24, 2014, the famous British scientist Professor Stephen Hawking once again shocked the physics community with his theory related to black holes. In the paper "Weather Forecast", Hawking pointed out that because the boundary of the black hole cannot be found.

So black holes do not exist, but gray holes do exist. This is to solve the firewall problem by assuming that black holes do not exist in the new theory, but they do not really exist.

The boundary of a black hole is also called the event horizon. Classic black hole theory holds that matter and radiation outside the black hole can enter the interior of the black hole through the event horizon, but no matter or radiation within the black hole can pass through the event horizon.

Hawking's gray hole theory believes that matter and energy will be released into the universe again after being trapped by a black hole for a period of time. He admitted in his paper that his initial understanding of the horizon was flawed and that light could actually pass through the horizon.
