I was watching this documentary I don't recall the name of. I remember recognizing Stephen Hawking though, which is one of the reasons one of the statements made in the documentary caused me to raise my eyebrow and question the rationale put forth.
Summarizing, the narrator said that in essence, no time exists inside (close to?) a black hole. A clock that would travel into a black hole would stop ticking, or so the audience were told. I suppose it's fair enough to reason time no longer exists inside a black hole, though from where I am sitting -no astrophysics background whatsoever- it sounds like quite the assumption.
Anyways, it was argued that the Big Bang itself, the event that supposedly caused the universe to exist as we know it (even though we know very little of it), was some sort of black hole imploding on itself.
It was then argued, that, therefore, no time existed before the Big Bang. The documentary further argued, that since no time existed before the Big Bang, it was therefore impossible for some sort of grand designer to have existed, let alone create the universe.
Now, I'm not exactly in favor of pointing to a grand designer that created it all, but this documentary narrates flawed reasoning for such grand designer to not have existed.
The link that is being drawn between one type of black hole (the ones we think we have in our universe, that exist with surroundings, in which time exists) and another type of "black hole" (the one we can only speculate about, for which it is assumed no surroundings existed, in which time could have existed), in that in each type of black hole, no time exists nor existed, neglects the fact that outside of such black hole, surroundings may exist or may have existed, other localities if you will, in which thus also time may have existed. It's not like current black holes cause time to not exist anywhere outside of it, right?
