Physicist Stephen Hawking revealed new theories on black holes in a presentation at KTH Royal Institute of Technology, Stockholm, this Tuesday.
According to The Washington Post, Hawking’s research revolved around a concept known as the information paradox. The concept refers to the fact that all information about the star’s formation inside the black hole is lost inside it, causing it to disappear. This paradox is impossible, according to current theories about our universe.
Hawking’s theory suggests that the star’s information is not found inside the black hole, but rather in its boundary, known as the event horizon. Acting as a shell around the black hole, all matter must pass its threshold to be pushed into it. When the remaining particles of the star come out of the hole, in an event called Hawking Radiation, they carry the preserved, stored information, outward.
The remaining information, however, is “in a chaotic and useless form,” Hawking said, comparing the remaining information to burning an encyclopedia. Nothing would be lost if the ashes are kept together, but it would be impossible to look up any information. When radiation leaves the black hole, information remains on the event horizon.
Nobel Prize winner Gerard t’Hooft composed research on a star’s loss of information, and has published several papers that will be compared to Stephen Hawking’s new findings. It is not known at this time if the findings find solutions to issues t’Hooft noted in his research.
