Greetings Space Cadets, Sad news today as world-renowned physicist Stephen Hawking has died at the age of 76.

He died peacefully at his home in Cambridge in the early hours of Wednesday, his family said.

The British scientist was famed for his work with black holes and relativity and wrote several popular science books including A Brief History of Time.

At the age of 22, Prof Hawking was given only a few years to live after being diagnosed with a rare form of motor neurone disease.

The illness left him in a Confined to a wheelchair and largely unable to speak, most of them were delivered through his famous voice synthesiser.

Stephen Hawking Quotes

Disability

“My advice to other disabled people would be, concentrate on things your disability doesn’t prevent you doing well, and don’t regret the things it interferes with. Don’t be disabled in spirit, as well as physically.”

Priorities

“My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.”

Barack Obama and Stephen Hawking

Free Will

“I have noticed that even people who claim everything is predetermined and that we can do nothing to change it, look before they cross the road.”

Aliens

“If aliens visit us, the outcome would be much as when Columbus landed in America, which didn’t turn out well for the Native Americans. We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.”

God

“God may exist, but science can explain the universe without a need for a creator.”

Stephen Hawking with Neil deGrasse Tyson

Artificial Intelligence

“The development of full artificial intelligence could spell the end of the human race. It would take off on its own, and re-design itself at an ever-increasing rate… Humans, who are limited by slow biological evolution, couldn’t compete and would be superseded”

The End Of The Universe

“It will take about a thousand million million million million years for the Earth to run into the sun, so there’s no immediate cause for worry!”

Hawking’s discoveries

• With the Oxford mathematician Roger Penrose, he showed that if there was a Big Bang, it must have started from an infinitely small point – a singularity.
• Black holes radiate energy known as Hawking radiation, while gradually losing mass. This is due to quantum effects near the edge of the black hole, a region called the event horizon.
• He predicted the existence of mini-black holes at the time of the Big Bang. These black holes would have shed mass until they vanished, potentially ending their lives in an explosion that would release vast amounts of energy.
• In the 1970s, Hawking considered whether the particles and light that enter a black hole were ultimately destroyed if the black hole evaporated. Hawking initially thought that this “information” was lost from the Universe. But the US physicist Leonard Susskind disagreed. These ideas became known as the information paradox. In 2004, Hawking conceded that the information must be conserved.
