If the same ball of clay shaped into a horse or into a car is swallowed by a black hole, would it modify the black hole in the same way, or is *all* information really kept on the event horizon making the two cases distinguishable?

Featuring Nobel Laureate, Theoretical Physicist Gerard ’t Hooft, Theoretical Physicist, Author Leonard Susskind, Physicist Raphael Bousso, and Theoretical & String Physicist Herman Verlinde with Journalist John Hockenberry Moderating
In the end, the holographic principle could reveal how to reconcile the two tremendously successful yet mutually incompatible pillars of 20th century physics: quantum mechanics and general relativity. “The holographic principle is a signpost to quantum gravity,” Bousso says, an observation that points the way toward a theory that will supersede our current understanding of the world. “We might need more signposts.”We may now be tantalizingly close to testing this bizarre proposition with observational evidence. Physicist Craig Hogan thinks he can see whether the holographic principle is pointing physicists in the right direction, by using lasers and microelectronics to measure "jitters" in the fabric of space, which would be produced from slippage of the tiniest binary units as they are jostled by quantum fluctuations.
“This is old-fashioned in a way,” Hogan says. “It appeals to this old-fashioned style of physics, which is, ‘We’re going to go out and find out what nature does, without prejudice.’ ”Check out the full article to find out exactly how Hogan plans to measure these minuscule vibrations at Scientific American
