thanks, i'l look it up. also what about black holes? the normal rules of physics are thrown out the window when it comes to black holes, would quantum gravity play a part here?
I have to write a short essay answering this question (1st year university level). I am finding it very hard to get any decent info on the net at all. If someone could help me out with this I would be very appreciative. Thanks.
