Stephen Hawking's Last Paper About Black Hole Is Now Accessible For You

The last ever research paper that comes from the hand of Stephen Hawking has finally become available to read online, and now you can read it.

After Stephen Hawking's death, most of us had belief that the paper named “A smooth exit from eternal inflation?” that was released on the 27th of April, 2018 would be the very last paper from his mind. However, true to his well-known incredible resolve, Stephen Hawking refused to go without leaving anything back. One of, if not the single greatest mind in the whole world had left us all a final gift before he passed away.

Just a mere two weeks before his death, Hawking had submitted the final version of his newest mathematics paper titled “A smooth exit from eternal inflation?” and it was approved on the 4th of March, a mere ten days before the world lost one of its most brilliant minds. The paper focused on the parallel universes concept and the way to confirm the existence of those universes. However, that was not his last ever paper like we all had thought. Another research paper from the famed scientist has recently shown up. Professor Hawking partnered with his colleagues from Harvard and Cambridge to write this paper that talks about his most favorite mystery objects, the black holes.

In this new paper that was co-written by Stephen Hawking, Sasha Haco, Malcolm Perry, and Andrew Strominger, the scientists has been re-examining the belief that the science community has been holding since forever that any and all information that an object was holding would be lost forever if that object is dropped into any kind of black hole. Most of the physicists do not doubt the belief that when you enter a smaller black hole, it would “spaghettify” your very being. This means that the intensely heavy gravity would essentially stretch your body in its entirety into an atoms string. After that process is finished, even in the case of you being able to get out of that black hole, there would be no way to recognize you as a human. Thus, it can be said that all of the information that can be used to define yourself have been lost. Well, that was what the scientists used to believe anyway.

In an undetermined time in the year 1974, Hawking had a realization that there is indeed temperature in all kinds of black holes. Thus, there must be entropy inside them. This new research makes a position that you can, in fact, record the entropy inside of the black hole through the photons that bounce around what we call the event horizon. These light particles make up some kind of halo surrounding a black hole that the research paper regards to as “soft hair”.


It also states that in the case an object goes into any kind of black hole, it should experience an increase in temperature, thus, therefore, a change in its entropy too. If that is true, then the information of the things gotten thrown in any kind of black hole is not lost completely. In fact, we can find it by measuring the soft hair or halo surrounding the black hole.

There are of course questions that need answers. The research paper does not only need to be reviewed by peers, but there are also limitations. This case does not account for all the things that we can throw in black holes. However, a lot of physicists do believe that this is indeed a promising beginning for any future research.

Out of the authors, Malcolm Perry of Cambridge was the one who put out this new insight, Andrew Strominger and Sasha Haco were the ones furthering the research along with Stephen Hawking. Perry was the one who finished all the work when Hawking passed away in March.

Perry recounted to the Guardian about the very last time he speaks to one of the most brilliant minds of this century about the paper before he passed away. He stated that it was quite difficult for Prof Hawking to communicate, to the point that Perry had to be put on something kind of like a loudspeaker in order to explain to the professor where the research had gotten to. Perry also added that when he explained it to Hawking, he simply smiled enormously as if he had known the final result already.
