dark matter/energy vs variable gravity...or neither?...
whats ur take...i kinda think dark matter is reaching...newton may have been a moron and got it wrong but there can easily be something else that causes galaxies to defy gravity...
i'm thinking the black holes at the center of galaxies (which we really don't know jack about) cause some sort of unexplained force that causes everything to spin at the same rate...

I fail to see how Hawking radiation changes anything in the long run. Will those particles have enough energy to fully escape? They pop out of existence on the "bad" side of the event horizon and back in to existence on the "good" side. Now what? Won't they simply be drawn back in the to black hole?
From the little I've read, I don't think they will...the idea is that Hawking radiation implies that information can escape a black hole...I watched one video that said that it meant black holes can essentially 'evaporate'.Fender wrote:I fail to see how Hawking radiation changes anything in the long run.

random drug induced ramblings .. i have a cold
there were a gagillion big bangs like a huge domino effect ..thus every black hole is the tail end of a bang
everything is moving away from the mother big bang and will eventually return to the start point "the mother of all black holes"
the world is not infinite .. in fact it's so small that for us to see it we would need to build a telescope larger then the world itself to see it because if the world was a basketball earth would be an atom .
so everything is relative .. we are in fact so small that the force of gravity is equivelant to using a crane to lift a flea.

Not information escapes from a black hole, what Hawking means a black hole can evaporate over time, that is correct (whereas before, it was thought that black holes could only gain mass - not lose it).
On the event horizon, physics is a bit extreme. Particles and counter particles can form here. If one particle has its velocity vector away from the black hole, and its counterpart ofcourse the other way (towards the black hole), the black hole just lost a little bit of mass.
A black hole could never explode like a big bang, and it's not certain if the K-value (Friedmann) is bigger then 0.

Some interesting reads on the information/hawking radiation bit
