If you don't mind travelling to a star in another universe - and only one-way - black holes could be useful for interstellar travel. Despite the general understanding of black holes, it seems that the time you will be exposed to infinite forces passing through a black hole is sufficiently short not to harm you. I have some difficulty accepting this, but Igor Novikov had some very convincing arguments last time I heard him talk about this. There are of course still the finite, but rather large forces pulling you apart the rest of the time, but apparently Novikov considers that a surmountable problem. ;-) Jacob (who is a physicist, but not an astrophysicist) -- Growing older is compulsory.
