Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory and say that time began at the Big Bang," he said during his lecture called The Beginning of Time. "Events before the Big Bang are simply not defined, because there’s no way one could measure what happened at them. ![]() Five years later, he was appointed Lucasian Professor of Mathematics at Cambridge, the most famous academic chair in the world (the second holder was Sir Isaac Newton, also a member of the Royal Society).ĭuring the 1980s, Hawking turned his attention to the Big Bang and the uncertainties about the beginning of the universe. In 1974, Hawking was inducted into the Royal Society, a worldwide fellowship of scientists. Professor Stephen Hawking experiences the freedom of weightlessness during a zero gravity flight. In this new paper, Hawking hypothesized that matter not only fell into the gravitational pull of black holes but that photons radiated from them - which has now been confirmed in laboratory experiments by the Technion-Israel Institute of Technology in Israel - aptly named "Hawking radiation". In 1974, Hawking published another paper called " Black hole explosions?", in which he outlined a theorem that united Einstein's theory of general relativity, with quantum theory - which explains the behavior of matter and energy on an atomic level. Over the course of his career, Hawking studied the basic laws governing the universe. This early work not only challenged concepts in physics but also supported the concept of the Big Bang as the birth of the universe, as outlined in Albert Einstein's theory of general relativity in the 1940s. In this paper, Hawking and Penrose proposed a new theory of spacetime singularities - a breakdown in the fabric of the universe found in one of Hawking's later discoveries, the black hole. In 1970, Hawkings and fellow physicist and Oxford classmate, Roger Penrose, published a joint paper entitled " The singularities of gravitational collapse and cosmology". Here are just some of the many milestones Hawking made in the name of science. Throughout his career, Hawking proposed several theories regarding astronomical anomalies, posed curious questions about the cosmos and enlightened the world about the origin of everything.

The couple had three children before separating in 1990. Just before his diagnosis, Hawking met Jane Wilde, and the two were married in 1965. A speech-generating device constructed at Cambridge, combined with a software program, served as his electronic voice, allowing Hawking to select his words by moving the muscles in his cheek. Talking grew more challenging and, in 1985, an emergency tracheotomy caused his total loss of speech. In that same year, Hawking also won the prestigious Adams Prize for his essay entitled "Singularities and the Geometry of Space-Time".įrom then Hawking went on to forge new roads into the understanding of the universe in the decades since.Īs the disease spread, Hawking became less mobile and began using a wheelchair. He also obtained his PhD in 1966 for his thesis entitled " Properties of expanding universes". Completing his doctorate did not appear likely, but Hawking defied the odds. Doctors told Hawkings that he would likely not survive more than two years with the disease. In early 1963, just shy of his 21st birthday, Hawking was diagnosed with motor neuron disease, more commonly known as Lou Gehrig's disease or amyotrophic lateral sclerosis (ALS). Hawking went on to Cambridge to research cosmology, the study of the universe as a whole. He attended University College, Oxford, where he studied physics, despite his father's urging to focus on medicine. 8, 1942 - 300 years to the day after the death of the astronomer Galileo Galilei. ![]() British cosmologist Stephen William Hawking was born in Oxford, England on Jan. ![]()
