The event horizon is the sort of shell around a black hole, past which all matter will be drawn into the dense object's powerful embrace.
According to Hawking's idea, the particles that enter a black hole leave traces of their information on the event horizon. When particles come back out — in a phenomenon called Hawking Radiation — they carry some of that information back out, preserving it. Technically, anyway.
"The information is stored in a super translation of the horizon that the ingoing particles [from the source star] cause," he explained, for those of you who like a little more physics lingo. "The information about ingoing particles is returned, but in a chaotic and useless form. For all practical purposes the info is lost."
At Monday's public lecture, he explained this jumbled return of information was like burning an encyclopedia: You wouldn't technically lose any information if you kept all of the ashes in one place, but you'd have a hard time looking up the capital of Minnesota.
