The process which leads us to state that "all things must have a cause" or "stuff can't come from nothing" can only be held confidently to be true in this state of the universe, as it is, as we perceive it's interactions now. All of -that- only goes as far back as the big bang. Before the big bang there could have been different physics...there could have been different -logic-. Perhaps stuff -couldn't- come from nothing in a hypothetical "before the big bang" if that phrase even makes sense......but we have no way of knowing that, and the reverse could just as easily be true. It's not strong enough a statement to lead, inexorably, to truth.
Well said. I'm tempted to say the laws of physics are the same in any universe - but I don't because such knowledge is currently far beyond human understanding, and perhaps always will be, confined as we are to this single cosmos.
