How does one get so large so early in the universe (i.e there is a quasar at z=7). Can it really accrete 10 million solar masses in that time? What are the micro-black holes that some predicted at CERN? I have a question, I think about wormholes! I don't know if you've seen the recent Star Trek film, not the really new one, the older new one! Old man Spock and the evil Nero both fall through a black hole and travel back in time, both popping out in the same place(ish)! Nero goes through very slightly before old man Spock, like a minute or less. But he then has to wait 20 years at the other end of the black hole for old man Spock to pop out. What's that all about?! By travelling back in time the minute gap has become a 20 year gap! I know it's a film but I've always wondered how much truth there is behind it! Also, old man Spock meets young man Spock now he's travelled back in time (probably by about 50 years or so) is there not some paradox about killing your grandmother or something? What if old man Spock killed his younger self? Would he spontaneously die too? Something on wormholes would be awesome too.
