Stephen William Hawking

Stephen Hawking is one of the most precious gems in the world of physics, who was ahead of his time. His disability of having unsteady feet and being diagnosed with degenerative disease couldn’t stop Stephen Hawking from becoming the world’s most famous and acclaimed scientist. Even his survival would have been a marvel to this world, but he lived amazingly till 76.

Who was Stephen William Hawking?

Stephen William Hawking was a British physicist, born on 8th January 1942. He is considered the most brilliant theoretical physicist of all time. He revolutionized the field of physics through his work on the origin of the universe and the black hole explosion theory. From the big bang to black holes, all his best-selling books appealed to physics lovers across the globe.

The English theoretical physicist whose theory of the explosion of black holes illustrated upon the theory of relativity and quantum mechanics. He also worked in the field of space-time singularities.

Stephen Hawking’s Education Awards & Achievements

Stephen William Hawking studied physics in 1962 at the University College, Cambridge and in 1966 in the Trinity Hall, Cambridge,. His contributions in physics are unparalleled, which often left other scientists scratching their heads.

Professor Stephen William Hawking holds 13 honorary degrees. He was bestowed CBE (1982), Fellow of Honor (1989) and the Presidential Medal of Freedom (2009).

He has received the Fundamental Physics Award (2013), the Copley Medal (2006) and the Wolf Foundation Award (1988). Along with a bunch of other honours awards and medals, he won the Adams Prize in 1966 for his essay Singularities and the Space-time Geometry.

He was also a member of the Royal Society, the National Academy of Sciences of the United States and the Pontifical Academy of Sciences.

The Physics of Black Hole

Stephen William Hawking’s name has always been associated with the black hole. He put forward his stroke of genius combining Einstein’s Theory of Relativity, which has already aroused curiosity and has been under debate for decades, and the theory of quantum mechanics. In the early 1970s, Hawkins turned his attention to both of these theories, and later on, Stephen William Hawking’s most famous thesis on black holes was proven right.

The Big Bang

Hawking’s doctoral thesis was written at a critical time when there was an argument between two cosmological theories: the Big Bang theory and the Steady State theory. Both these theories were considered to be opposing each other at that time. However, both theories accepted that the universe is expanding, but the first one explains that the universe is expanding from an ultra-compact, super-dense state at a finite time in the past, and the second one assumes that the universe has been intensifying forever.

Hawking showed in his thesis that the Steady State theory is mathematically self-contradictory. He reasoned instead that the universe began as a dense point called a singularity which was infinitely small. His description has been accepted worldwide today.

Hawking Radiation

The photons or the particles of light can’t escape from the black holes because of their intense and strong gravity. But Stephen Hawking argued on it, explaining the truth, which was more complex than the assumed fact. He applied quantum theory, especially the idea of “virtual photons”; he realized that some of these photons could appear to be radiated from the black hole. At a laboratory experiment in the Technion-Israel Institute of Technology, it has recently been confirmed that this theory is correct and is named Hawking Radiation.

Instead of a real black hole, the researchers used a “sonic black hole” from which sound waves cannot outflow.

The Multiverse

Stephen Hawking was also involved in the most exciting topics toward the conclusion of his life was the multiverse theory. He proposed the idea that our universe, with its start in the Big Bang, is just one of an infinite number of contemporaneous bubble universes. In his very last paper in 2018, he proposed a novel mathematical framework and tried to seek out the universe in his own words. But as with any assumption concerning parallel universes, we do not have any idea if his ideas are right now. Maybe the scientists will be able to test his belief in the coming times.

Not only an amazing physicist but Stephen Hawking was an amazing and inspiring personality too, he left behind his great research theories and thoughts as his legacy to us, which is truly a gift in physics.
