Black Holes and Cosmology, anyone? If these two words occur in a conversation you would concur that the famed British physicist Stephen Hawking is being talked about. While people were still reeling under the aegis of the theory of relativity Stephen Hawking was considering space and cosmology on a different level. He is most renowned for this theory of Cosmology.
- Theory of Cosmology
Stephen Hawking seconded Alexander Friedmann’s theory of physical cosmology and brought forth the belief that the cosmos started as a singularity. This came after extensive research of the theory of relativity.
- The infinite in Time and Space
In his co-authored book with George Ellis, a South African Professor of applied Mathematics, hawking dabbled with the how Space and Time stretch to the infinite. This expansion into the inestimable was being its primal nature.
- The Second Law of Black Hole Dynamics
Now if you have been a fan of science fiction you are well versed with the end of the world and it being swallowed up into a big black hole. Stephen Hawing was ahead of his time and in the year 1970 he published the second law of the Black Hole dynamics, stating that the event horizon of a black hole can never get smaller.
- Radiation according to Hawking
The term Hawking’s Radiation coined by him stated that black holes would emit radiation constantly until their energy was spent and they would evaporate eventually. After he came up with this theory he got immense academic recognition and was called to Cambridge as a senior academician in gravitational physics. In 1975, he was awarded the Eddington Medal and the Pius XI Gold Medal for his outstanding investigations in astrophysics.
- Inflation Cosmology
British theoretical physicist, Gary Gibbons and Hawkings carried out a workshop, ‘the Very Early Universe’ that proposed how the universe expanded after the Big Bang. They proposed that early on the expansion was at a greater pace, which then settled into a slower pace as time went by.
- Harlte- Hawking State
American Physicist, Jim Harlte and Hawkings developed a theory called as the Hartle – Hawking State. The theory proposed that before even the earliest movements of the Big Bang, the Plank Epoch, took place the universe did not have a boundary in space and time as time itself was non existent.
Stephen Hawking was one of the greatest brains of our time. The theories he proposed sent the physics world on discoveries about space and time that we, as a people, as still discovering. His recent departure from the world has left a big void… a black hole in own terms.
