Stephen William Hawking CH CBE FRS FRSA, an English theoretical physicist, cosmologist, author, and Director of Research at the Centre for Theoretical Cosmology in the University of Cambridge, who reshaped cosmology and brought science to very large an audience with his most popular book “A Brief History of Time” died at the age of 76. Professor Stephen Hawking died in the early hours of Wednesday morning at his home in Cambridge, England.
The statement was emailed by a spokesman for his family. In the statement, his beloved children, Lucy, Robert, and Tim said: “We are deeply saddened that our beloved father passed away today. He was a great scientist and an extraordinary man whose work and legacy will live on for many years. His courage and persistence with his brilliance inspired people across the world. We will miss him forever”.
Though the family did not reveal the cause of his death, they stated that he “died peacefully”. Professor Hawking suffered greatly from amyotrophic lateral sclerosis, also known as motor neuron disease or Lou Gehrig’s disease. He is known as one of the longest survivors of ALS.
THE ORIGIN OF ‘BIG BANG’ THEORY
Professor Stephen Hawking applied the quantum theory (the theory which governs the world of sub-atomicity) to black holes. In it, he gave a claim that discharge radiation causes black holes to disappear. He laid a splendid ground which helps to explain the notion that black holes have existed at a micro level, and the smaller they are, the faster they evaporate.
Black holes, first predicted by Albert Einstein in 1916, is a region of space with such strong gravitational attraction or effect that nothing, not even particles such as light can escape from inside it. Detected by the movement of surrounding matter, they devour everything in their path and may play a role in the birth of galaxies.
With the aid of mathematician Roger Penrose, Hawking used Einstein’s theory of relativity to detect the origin of light and space to a single point of zero size and infinite density. For this very reason, their work gave a mathematical expression to the Big Bang theory. This theory was later proposed by a Belgian, Georges Lemataire in the year 1927. This theory was supported by Edwin Hubble’s discovery that the university is expanding. For 30 years, Hawking was appointed as Cambridge’s Lucasian professor of mathematics. In 2009, U.S president, Barack Obama awarded professor Hawking the Presidential Medal of Freedom, during the year of his retirement. Hawking was appointed a professor in 1977 with a chair in gravitational physics.
In 1983, Hawking spent much of his time, with the aid of Euclidean quantum gravity to black holes, to discover or develop the quantum theory of gravity. In that year, he and his colleague, Jim Hurtle at the University of Chicago teamed up in their findings. From these two geniuses, the WAVE FUNCTION OF THE UNIVERSE was brought forth; which says in theory that it could be used accurately to calculate the properties of the universe we see around us today.
