How do i contact stephen hawking




















The only slight drawback was the fact that the Equalizer only had one accent: American and Stephen was very much British.

Gradually, Stephen lost the use of his hands but being ever-determined! Thanks to Richard Branson, in when Stephen was 65 years old, he got to take the trip of a lifetime: heading off to experience zero-gravity.

While floating in space, Stephen ditched his chair and even managed to do backflips! Of course, this being Stephen, he wanted more — and publilcy declared his ultimate goal: to travel into space. This eventually led, in , to the revelation that black holes have a temperature and produce radiation, now known as Hawking radiation, a discovery which revolutionised theoretical physics.

Some forty odd years later, the precise nature of this entropy is still a puzzle. This is probably the greatest mystery facing theoretical physicists today. To understand black holes and cosmology requires one to develop a theory of quantum gravity.

Quantum gravity is an unfinished project which is attempting to unify general relativity, the theory of gravitation and of space and time with the ideas of quantum mechanics. Hawking recognised that quantum mechanical effects in the very early universe might provide the primordial gravitational seeds around which galaxies and other large-scale structures could later form. This theory of inflationary fluctuations, developed along with others in the early s, is now supported by strong experimental evidence from the COBE, WMAP and Planck satellite observations of the cosmic microwave sky.

This idea allows one to explain the creation of the universe in a way that is compatible with laws of physics as we currently understand them. However, it was his popular science books which took Professor Hawking beyond the academic world and made him a household name. The first of these, A Brief History of Time , was published in and became a surprise bestseller, remaining on the Sunday Times best-seller list for a record-breaking weeks.

He also collaborated with his daughter Lucy on a series of books for children about a character named George who has adventures in space. He had suffered from a wasting motor neurone disease from the age of 21 which meant he was confined to a wheelchair for most of his life and forced to use an electronic voice synthesiser. Under an "Acceptance in Lieu" agreement announced on Wednesday, his vast archive of scientific and personal papers will go to the University Library in Cambridge, where he lived, while the entire contents of his office will be passed to the Science Museum Group.

Cambridge University Library has been given the paper archive of late British physicist Stephen Hawking, while London's Science Museum will receive the contents of his office, which curators plan to reconstruct as an exhibition, London, Britain, May 26, In his later years, Hawking repeatedly warned about the dangers of humankind meeting alien civilizations.

In his documentary series Into the Universe with Stephen Hawking , he suggested that alien civilizations sufficiently advanced to visit Earth may be hostile. How would we react to alien visitors?

A recent study says we might be surprisingly sanguine. Hawking also voiced alarm over the potential power—and downsides of—widespread artificial intelligence AI , which he feared could pose an existential threat to humanity. Humans, who are limited by slow biological evolution, couldn't compete, and would be superseded. Hawking was not alone airing concerns over AI research.
