“It is no good getting furious if you get stuck. What I do is keep thin...” — Stephen Hawking Quote

“It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.”

“I had not expected 'A Brief History of Time' to be a best seller. It was my first popular book and aroused a great deal of interest. Initially, many people found it difficult to understand. I therefore decided to try to write a new version that would be easier to follow.”

“We knew about black holes in other ways, and we knew about neutron stars - well, those are the two things that ultimately got seen.”

“Things changed with the discovery of neutron stars and black holes - objects with gravitational fields so intense that dramatic space and time-warping effects occur.”

“The early universe was a dusty place, and the UV radiation from the hot, young black holes and stars would get enshrouded by dust, re-radiated, and scattered into red wavelengths like infra-red, causing these objects to remain obscured.”
