I'm pretty ignorant in physics, so please help me out. OK... So I was watching the special "How The Universe Works", and the episode was about the origins of the universe. (Lame, I know, but Netflix had nothing else that was interesting). They keep talking about the speed at which the Big Bang created the universe, which was something like a millionth of a millionth of a millionth of a millionth of a second to expand from the size of a golf ball to the size of the Earth. They go on to describe Planck time and more exact figure and stuff, but my question is more general. The question is this: How are we even able to measure any form of time, when (at least as it has been explained to me), time was created with the Big Bang? I mean... they talk about expansion into not even space, just emptiness or whatever existed before the Big Bang... so how can we even give that a referenced scale? Is our initial point of reference just referring to the first observable time unit within the universe and its expansion from that? Because to me it seems like everyone talks about it as though the 'emptiness' that existed before the Big Bang can still be measured in time. This also goes along with the question about how the Big Bang expanded faster than the speed of light. If anyone could shed light on this (please avoid the obvious pun) then I would be grateful. If my question is being asked incorrectly, please logically explain to me what is wrong with it so I can understand. Thanks!
