Here are some links about black holes..
The interesting thing about black holes is that nothing
�should� come out of them, (according to Steven Hawking)
but he (hawking) later revised his theory saying something DOES
make it out of the black hole, information.
This I believe is where management gets their ideas from,
some place where random bits of the universe got tossed,
everybody thought that those things were gone
for good, but no� little bits of them leaked out.
