oh really? Hmm if I could remember Neil Tyson from this one podcast explaining this exact topic. Eventually black holes will eat everything....eventually

Maybe I heard it wrong, or interpreted it wrong...Black holes will eat anything, even light can't escape a black hole(probably heard this a billion times). Unless you're talking about the gamma ray burst? Maybe I'm confused about black holes in general. I'm not a physicist(yet)!

nothing can escape their pull... once you are inside the even horizon. if an equal mass black hole replaced the sun our orbit wouldnt change

Black holes will absorb anything that gets close enough to it, but I don't believe there is any evidence to suggest they keep growing and will absorb everything though. They also don't last forever, they very slowly radiate energy/mass and eventually disappear.

big bang=false
universe was created by Jesus

they only disappear if they are small enough. otherwise their gravitational pull is able to bring in enough "stuff" (EM waves, matter, etc) to keep it alive.

if hawking radiation can be confirmed then even the largest black hole would very, ...., very slowly dissipate if there is nothing left in reach to be pulled in

Taken from http://en.wikipedia.org/wiki/Hawking_radiation

The CMB gives the black hole enough energy so that it doesnt quite dissipate unless below a certain threshold.

I guess you could argue that since the strength of the CMB diminishes with time, that eventually larger and larger black holes will not be sustainable by it.

True, but the rate of cooling in the universe is so slow that I think that can be negated unless talking about timescales on the order of billions of years

and isn't that what one is talking about in terms of the universe anyhow?
