Not exact matches
But when the math says that a black
hole's
store of
information is measured by its surface area, does that merely reflect a numerical accounting, or does it mean that the black
hole's surface is where the
information is actually
stored?
The answer depends on whether you view the black
hole from the outside or from the inside — and from the outside, there's good reason to believe that
information is indeed
stored at the event horizon.
These particles would in effect serve as recording devices that
store information, providing clues about the original material that went into the black
hole.
However, the new research suggests that the
information encoded in particles falling in could remain
stored at the black
hole's point of no return, or event horizon, until that black
hole evaporates.
Joseph Polchinski, Firewall Institution: University of California, Santa Barbara Year: 2012 Known for: Discovering D - branes, explaining what D - branes are (a string theory thing) Idea: Once a black
hole has lost about half of itself to Hawking radiation, the event horizon can no longer
store enough encoded
information to tell the story of what's inside.
In particular, Hawking and Penrose disagree on what happens to the
information stored in a black
hole and on why the beginning of the universe differs from the end.
The artist invites us to contemplate the suggestion of planet earth as a black
hole, where all planetary matter has been swallowed and
