I have to agree with you, I found his question to be exceedingly naive. Will we still be here in 100 years?(paraphrased). Life was much worse 100 years ago. The average life expectancy in the US was 47 years old, it is now approaching 80. There were no social programs, minorities and women could not vote. In 1918, millions of people were killed by influenza, and World War 1. 100 years ago there was incredible "global" poverty , very limited technology, few had electricity or cars, planes weren't invented yet, and we had World War 2 and Fascism and Communism, and the Great Depression to look forward to. The average American didn't graduate high school. Many impoverished peoples black and white were sharecroppers, which was basically "indentured servitude". They worked a plot of land, and got to keep part of the crop to subsist on. More toilets were outside rather than in. The mode of heating was more generally a fireplace or a stove. The average American had a pair of work clothes, and a Sunday suit, but just one pair of shoes for both. They were making a dollar a day. I remember my grandmother saying girls would use a form of hog grease for make-up, no one could afford the real. I could go on and on, but I'm not nearly as intelligent as Professor Hawking. If we got through our past, we can get through the future, everyday we're bombarded by the media with what's bad, but one thing that wasn't so bad back then, was probably the lack of television, and computers(with so-called "genius" Professors) to forecast doom all the time and stir things up.

Answer 4

He didn't really "invent" anything. He's known for his advanced theories, his most famous of which is the idea that black holes are not really "black", they actually give off radiation.

Everywhere in the universe, at the sub-atomic scale, virtual particle pairs (one matter, one antimatter) are constantly being created but they annihilate each other and disappear before they really have any effect on anything. Near the event horizon of a black hole, however, one particle gets sucked in and the other escapes before they can annihilate each other. The particles that escape are "Hawking radiation" and they eventually cause the black hole to lose energy over time.

Answer 5

His key scientific works to date have included providing, with Roger Penrose, theorems regarding singularities in the framework of general relativity, and the theoretical discovery that black holes emit radiation, which is today known as Hawking radiation (or sometimes as Bekenstein-Hawking radiation).[2] His scientific career spans more than 40 years and his books and public appearances have made him an academic celebrity and world-renowned theoretical physicist. He is an Honorary Fellow of the Royal Society of Arts.[3]

Answer 6

As one answer correctly said, he used quantum mechanics to predict radiation from black holes. This is an important finding because, before Hawking's radiation, most everyone thought that, like Las Vegas, what went into a black hole stayed in a black hole. But, to my way of thinking, his work is even more significant in another respect.

Hawkings radiation is the first and, maybe, only theory to date based on quantum mechanics that has been validated for macro physical phenomena. Up to now, quantum theories have been validated only for subatomic scales of physical events..like photo-electric effects for example. Perhaps, just perhaps, quantum math can be applied to other macro phenomena, like gravity maybe. [See source.]

Answer 7

He is a leading physicist who among other things, discovered that Black Holes are not black but emit radiation. This radiation is because pairs of particles pop in and out of existence in space all the time and when a pair pops up near the event horizon of a black hole, sometimes one of them comes into existence within the event horizon and it gets sucked into the black hole while its counterpart is free to escape.
