I have just finished reading Carl Sagan's novel *Contact*
and must say that I enjoyed it very much. I do have some
questions for anybody in the know:

1) I have heard of wormholes (the means used for travel at
   velocities >c in the novel), but always thought that
   they were just the result of informed speculation.
   Do they (or could they) really exist?

2) What are the differences between wormholes and black
   holes?

3) I understand that Stephen Hawking has established a means
   whereby black holes can 'evapourate' through the emission
   of large scale gravity waves, smaller black holes being
  almost explosive through this mechanism. How, then, could
   mini black holes have hung around since the Big Bang?

4) Can causality really be violated in the immediate vicinity
   of a black hole (or beyond the event horizon)?
