Freely available published the latest work of Stephen Hawking

Stephen Hawking was a prolific author with a knack for making books on challenging scientific topics engaging to a wide spectrum of readers.The physicist is best known for his best-selling 1988 classic 'A Brief History of Time: From the Big Bang to Black Holes, ' which was meant to help people without a strong scientific background understand key questions of physics and human existence.

The final paper he contributed to, titled "Black Hole Entropy and Soft Hair", concerns what theoretical physicists call the information paradox - what happens when an object falls into a black hole? It has now been written up by his colleagues at Cambridge and Harvard universities and posted online, the Guardian reported on Wednesday.

Selling had contended that dark openings have a temperature.

If an object is put into a black hole, the hole's temperature is bound to be affected as well as its entropy, a measure of an object's internal disorder. It is basic physics that tells us that no information can ever be lost.

In the most recent paper, Hawking and his partners indicated how a portion of the data might be protected.

That theory is being explored by fellow scientists including Perry, who told the Guardian: "We think it's a pretty good step but there is a lot more work to be done". But if you exit the black hole, then you can recognize that as a person. It States that certain information can survive sucked into a black hole.

In 1974, Hawking argued in a now-famous study that besides mass and spin, black holes can be characterized by a unique temperature and that they don't just devour matter, but emit radiation.


The late physicist's final paper on black holes and the information paradox has been revealed by his colleagues.

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

"However, this does not resolve the paradox".

The new paper showed that Hawking, together with his team, discovered a mechanism that can count the information carried by soft hairs - they are made of photons or gravitons (hypothetical particles of gravity). "It's telling you that soft hair really is doing the right stuff".

Strominger concluded that "this is excellent progress, but we have much work yet to do".

While Hawking's final work may have marked the end of his journey across the vastness of space, it is also a reminder that his contribution to our understanding of the universe continues even in his absence.
