Basic "Big-Bang" ?'s For First Thread I know this question is on the basic theory of the Big-Bang, but I'd like to propose simpler questions as my first thread starter (I literally just signed up to the site) in hopes to read the forums user replies and thus learning more about the different views, theories, and explanations. I feel I can learn much here, and so would love to see scientific minds such as yourselves answer simpler questions in relation to the most known and accepted theory, the Big-Bang. (To read the separate views and arguments made from answering questions that don't have any definitive proofs to answer with absolute certainty helps me see and understand another viewpoint besides the widely accepted, and typical one that is theorized and therefore defined "correctly" by the masses) 1. How do we know space-time was created by the Big-Bang along with everything else? 2. If space-time was nonexistent before the Big-Bang, then how did the Infinitesimal singularity which eventually blew up as the Big-Bang blow up? Wouldn't this singularity remain forever "paused" as a motionless point of infinite energy and mass suspended in a friction-less state? How could energy and mass exist this way if this is so? 3. Why couldn't space and/or time have existed before the Bang? The Big Bang created everything within the universe but how do we know the universe itself didn't already exist; In 'time' the Big Bang blowing up and basically giving a universe full of empty space a vast amount of energy and mass? So my ultimate question (although feel free to answer or post on any or all of them) is could space and/or time have existed before the Big Bang?
