If the Big Bang model is incorrect that why are predictions based on the model confirmed so precisely by measurements of the cosmic microwave background? (And specifically by the 'ripples' therein).

Many people believe that the universe goes through "big bang cycles" and that it has been doing so forever- is there any way that we would be able to verify this?
​
I'm not sure that many people actually believe this anymore. But, theoretically it might be possible to have a model that predicts a 'bouncy universe' that could be verified through other predictions made by that model. I can't see any way you could confirm it by direct observation, however, since the Big Bang would destroy all evidence of what was before it.

Re: Information that enters a black hole.
Do black holes emit "information" as they decay? (keep in mind physisists are using information in a very specific sense here) The anwswe is... sorta.
​
I think you'll find the most recent answer is: yes. There's an article about it in the November issue of Scientific American.
