[Polybius]

I just finished watching a doc on Stephen Hawking's paradox - 'information paradox'. It explained how he tried to prove that black holes can die out and disappear from existence along with all the information stored in its infinite singularity. Physics doesn't seem to allow this loss of information. They state that information can never really be ever lost, only harder to retrieve.

But what then existed before this universe? Before the Big Bang. I always thought that absolutely nothing existed before it. Not even information. Doesn't that prove that it's possible for information to be destroyed and not to exist at all. Why doesn't physics then allow it?
