I would classify this question in a cousin catagory to whether god exists or not. The reason I say that is all intelligence (information) would by neccessity be void at the originating singularity our universe may have 'burst' from. since we would have no means of measuring or proving the existence of said information, it would be almost as implausible as trying to measure a 'supernatural being' such as a god.
We may be one of many universes, our universe may 'recycle itself', or any miriad of possibilities which we have never considered.
all we can do is speculate... and eat cookies
Okay. Follow me on this. If time can be measured by means of a clock this would indicate it's existence, right? Measuring a thing causes the thing to be effected and one cannot effect a thing that does not exist. If it has existence then it has to have an entropy of at least S=1 since that is the minimum for existence. If the BB had an entropy of S=1/0 which is the most it could have since it was before the existence of the universe and had to have an entropy greater then S=0 which is non-existence, then time could not have existed before the BB. If time has an entropy greater then S=1/0 then it could not exist in a state of higher order then it's self. Does this make sense?
I'm not sure on this one, but I saw an episode of "Through the Wormhole"--it was a miniseries about modern physics with Morgan Freeman as the host--that proposed something interesting: that time doesn't really exist at all, only in the mind of the observer. It basically was saying that the whole of reality, past, present, future, exists now how it always has and always will, and it is fixed, but as sentient beings (and this part is mostly me, interpreting...) our brains cannot understand the universe in this whole way. Rather, we have to relate things in a relative manner, from one moment to the next. The TV show used the analogy that time is really like a temporal currency, like a heart beat or any other measure you could come up with. The concept of time was invented by humans because of the way we experience reality, but since we already know our own perceptions and senses can't be truly trusted in the strictest, most scientific way, it is possible that time does not exist at all.
Most interestingly, they also talked about the history of the physics equations involved in this idea, and how one scientist (sorry I forgot the name right now) fixed the problems in one fundamental equation by removing the factor of time. Food for thought.
