I take an interest in physics in my spare time (in IT during the day). I have a query regarding the 'problem' of information loss at a black hole, and would be grateful for some enlightenment. It seems generally regarded that any information going past the horizon of a black hole is 'scrambled' and irreversible. I mean 'information' in the sense of 'the sum of bits required to accurately describe the object'. I was wondering whether that is assumed as truth or whether this is an irreversible process. Possibly: Consider the bits of information like a 'tape' of 1's and 0's. Information gets added onto the disc of the black hole in a serial fashion. I'm thinking that almost all of the black hole will be equally dense, but surely when new information is being added in, its not going to be perfectly uniform in shape and perhaps new information would have a designated place to be 'written to' the black hole The information would be preserved Is this 'way off' and what'd be the best thing(s) to read with regards to the subject of information preservation/loss (I have a good head for maths but lack the further education for it). Thanks for any pointers.
