Before we can answer the part about the big bang, we must first delve into the potentially speculative nature of time. Contrary to the Newtonian idea of time – where it is perfectly regulated and completely uniform – time is currently thought to be completely relative. Since the dimension above us adds duration, we “Fold” through the fourth dimension and experience it one Planck Time at a time. Planck Time therefore is just the amount of time required for light to travel Planck Length in a vacuum. Now, to address the big question: “Was there time before the big bang?” Simply, we have no idea. Even if time did exist prior to the big bang, we would have absolutely no frame of reference by which to measure it.
