    The ergosphere around a black hole is full of matter that's orbiting the black hole

    Does this mean that the mass of the blackhole is increasing as it picks up stray matter?

    "Only the powerful gravity of a very massive black hole could propel a star with enough force to exit our galaxy," explained Brown.

    As far as I understand it black holes are created when stars collapse and gravitation force depends on the amount of matter present. So why would a black hole produce a greater gravitational force at a distance than any massive star? And why would a great force at the centre of the galaxy be inclined to spit out stars at huge velocities? I assume the companion star is relevant.

    That being said, his appeal seem rather limitied to certain segments of the population such as science and IT types. The BBC national poll placing the Hitchhikers Guide to the Galaxy in England's top 5 favourite books would seem to indicate that his appeal is universal. He may have written science fiction but his books are really a hilarious satire on everyday life.
