Stephen Hawking was a well-known cosmologist and theoretical physicist. He was born in England on January 8, 1942. He is well-known for his contributions to cosmology, gravitation, black hole quantum theory, thermodynamics, and information theory.
His best-selling book “A Brief History of Time” is one of his most well-known works. In his own words, a complete comprehension of the Universe is also offered, as well as “My purpose is simple,” which explains the Universe and why it exists. He has won numerous honours, including the RAS Gold Medal, the Royal Society Copley Medal, and the Presidential Medal of Freedom. This article discusses Stephen Hawking’s six most important findings.
Stephen Hawking’s six most important findings
1. 1970 – Singularities
Singularities, or points where space-time appears to be infinitely curved, are also mentioned in Einstein’s theory of gravity. But it wasn’t obvious at the time whether singularities were genuine or not. Roger Penrose then demonstrated that singularities might develop in black holes.
Later, Stephen Hawking completed ground-breaking work on singularities and applied it to the entire Universe, claiming that singularities are caused by gravitation. He also stated that Einstein’s hypothesis, which was the big bang theory, predicted a singularity.
2. Black Hole Mechanics Laws – 1971-72
The laws of black hole mechanics were discovered by Stephen Hawking. His first law asserts that the black hole’s total surface area will never shrink. The Hawking area theorem is another name for it. According to another law, black holes were extremely hot. Classical physics, on the other hand, states that black holes do not radiate heat.
– Another law is the black hole “no hair” theorem, which claims that black holes may be described by three numbers: mass, angular momentum, and charge. Radiation is emitted by black holes, which may persist until they run out of energy and dissipate. Hawking radiation is another name for this phenomenon.
– For his work “Black Holes,” he received the coveted Gravity Research Foundation Award in January 1971.

3. Theory of Cosmic Inflation – 1982
In physical cosmology, cosmic inflation is a scenario in which the Universe expands exponentially soon after the big bang, as proposed by Alan Guth in 1980. Hawking was also one of the first to compute quantum fluctuations, which are minor deviations in the distribution of matter that can lead to the proliferation of galaxies in the Universe during inflation.
4. Model of the Universe’s Wave Function – 1983
He was interested in developing a quantum theory of gravity, but in 1983, he released a model called the Hartle-Hawking state with James Hartle.
According to this idea, time did not exist before to the big bang explosion, and hence the concept of the universe’s beginning is meaningless. There are no original time or space limitations in the Universe.
5. His famous book “A Brief History of Time” was published in 1988.
He covers a wide range of topics in cosmology in this book, including the big bang, black holes, and light cones, among others. This book became the best-selling book in the United Kingdom, breaking the previous record of 237 weeks in the Sunday Times best-seller list.
6. Top-Down Cosmology Theory – 2006
In 2006, he and Thomas Hertog proposed the “top-down cosmology” theory, which asserts that the Universe consists of a superposition of many alternative initial circumstances rather than a single unique initial state. Several more works, such as The Universe in a Nutshell (2001), God Created the Integers: The Mathematical Breakthroughs That Changed History (2005), have also been released.
As a result, we now have knowledge of Stephen Hawking’s well-known and significant discoveries.
