I keep hearing in these Science Channel programs that the reason why the Big Bang banged (instead of immediately collapsing into a black hole) is that when it banged it made space to expand faster than the speed of light. I'm always puzzled on how sure and certain the speakers look in these programs - even going like this: "the rule is that mass cannot go faster than light, but space can". Wow... which rule is that?
This idea about space expanding faster than light is fine as a hypothesis, but doesn't scientific method require scientists to actually prove it by measurements before ascertaining that as a fact? As far as I know nobody really measured that anywhere, is that true? That is, this is not a proven fact, but the best explanation for what we can know at this moment - an Occam's Razor thing?
If so, is it possible that this idea of space can expand faster than the speed of light may just be a fitting explanation that 100 years from now someone may say "Of course it can't go faster than light! In the early universe the speed of light was much, much faster than today!" (or whatever else) and that will then become something that the majority accepts as a new dogma?
