Okay, I'll go with a question (and, oh, my first post here!):

We know(*) that black holes exist, but what about white holes? Do they exist? Could they even theoretically exist?

(*) For a given value of "know".

Hmm...now, do I want to give my real name, being pretty sure you won't be able to pronounce it properly... let's see:

Jamas Enright, Wellington, New Zealand
(Jamas is like Shamus, but with a J.)
