Stephen Hawking's Final Paper Was Just Released

The paper demonstrates the possibility of recording black hole entropy changes via what they dub "soft hair".

"The authors have to make several non-trivial assumptions so the next steps will be to show that these assumptions are valid", said Marika Taylor, professor of theoretical physics at Southampton University and a former student of Hawking's.

Hawking's final paper was the third in a series of papers looking at black holes, a concept he spent decades studying, particularly the black hole information paradox.

The new paper suggests that objects thrown into a black hole may change its temperature - and its "entropy", a measurement of its internal disorder.

The greatest physicist and cosmologist of our time, Stephen Hawking died at 77 year of life March 14, 2018. Then he made a discovery - the universe and all of its surrounding space and the universe have their clear boundaries and limits. Some theoretical physicists believe they do, while others do not. He was not aware of how ill Hawking was and called to give the physicist an update. The English scientist was interred in Cambridge.

Apparently, if it's proven that the information disappears together with the black hole, it would contradict the quantum theory which states that nothing is really ever lost.

It involves the extreme denseness of black holes, these objects capable of warping time-space which form when very big stars collapse within themselves or when two stars collide onto each other.

The study shows that the "soft hair" of the black hole can record its entropy.

In this latest research, Hawking, Perry and Strominger joined forces with Cambridge's Sasha Haco to calculate the entropy of a black hole that has a certain kind of soft hair.

Hawking said this 2010 book co-written with American physicist Leonard Mlodinow was meant to address important unanswered questions such as why there is a universe and whether the universe needed a creator and designer.

"It was very hard for Stephen to communicate and I was put on a loudspeaker to explain where we had got to". They argued that some information from the black hole can be preserved before it completely disappears. When I explained it, he simply produced an enormous smile.

In the scientific article experts headed by Stephen Hawking was trying to understand the properties that may have individual items in contact with the singularity. The classical view of physics regarding black holes told us that nothing, not even light, could escape their grasp. "He knew the final result", he said.
