According to Prof. Stephen Hawking, black holes should not be viewed as eternal prisons any longer. The British physicist’s calculations revealed that the cosmic objects may in fact leak the material they had swallowed before they explode.
But the fate of the objects sucked in by a black hole remains uncertain. In a recently published paper, Hawking tried to explain what may happen with the matter that falls into one such voracious cosmic pit.
The researcher tried to solve a decades-old paradox related to black holes. While some theories claim that objects lost within a black hole are lost but the information about them survives, other theories claim that both the objects and the info are lost.
In his paper, Hawking and his colleagues presume that some part of that info is preserved so the object is not lost forever. The findings are consistent with Hawking’s earlier statements that things trapped into a black hole should not give out hope.
“Black holes are not the eternal prisons they were once thought,”
he said in a 2015 interview.
But don’t expect to escape a black hole and return home. The physicist believes that black holes are gateways to alternative universes. Yet, the black hole needs to meet some criteria to be qualified as such. The primary requirement is for it to be large enough and rotating.
He said that although he is very keen on space flight he would skip testing his own theory.
Hawking’s hypothesis that the information is preserved within a cosmic hole is in line with the rules that prevent the universe from falling apart. For example, if the information about an object lost in a black hole would simply vanish too, this would mean that the Universe has no memory of past events so past does not exist at all.
Hawking underlined the importance of the past. He noted that past is the thing which provides us with an identity. Without it we wouldn’t know who we are anymore.
Now, there’s another problem scientists need to solve. It is unclear where all the information about lost material in the abyss of a black hole is stored. According to an old theory, the info is preserved in its “hairs,” which are located on the edge of the black hole.
