Surely, if time is reversed then so is causality, hence the time invariance of the fundamental laws.
If time were reversed, wouldn't that be super-natural?
The key piece of data in Peeper's reply is that the laws of physics are time invariant. That means the laws are the same whether time runs backward or forward. One of the mysteries of modern physics is the cause of time's arrow. Why does time run forward and not backward, because there seems no physical imperative that it be so. There are many layman-level books that devote space to discussing such issues.
Anyone who witnessed smashed pieces of porcelan suddenly coming to coming together into a pristine cup which then lept off the floor and up into their hand would likely consider it a supernatural event, I know I would, but there is nothing in the laws of physics as currently understood that disallows this.

So the ID creationist must debate/discuss science with, as Rush Limbaugh would say, "half our brains tied behind us," in that evolutionists are allowed to debate/discuss science which is "mysterious" and science of which there is "no physical imperative that it is so,", whereas we, the ID creationists are not allowed to share this advantage. For to to so would be nonsensical talk. Is that fair and balanced, Percy?
There's a thread elsewhere for discussion of moderator issues, so I'll only comment here that there's no logic to saying that if there's something we don't know then we're free to ignore the things we do know. You are not free to disregard the known laws of physics simply because time's arrow is not represented in the equations.
But if time were reversed, how would this model be less scientific than Peeper's model?
I was only reinforcing Peeper's comment about time reversal by providing a little more detail, not introducing a different model.
My suggestion to you hasn't changed in over a year. Educate yourself on a topic before discussing it. Please don't allow this thread to be taken over by another discussion about whether you know what you're talking about.

Re: Time reversal.
Let me venture into further misdeeds by highly recommending the book Time's Arrow, a work of fiction by Martin Amis in which Tod Friendly dies only to "awaken" and find time running backwards toward the horrors of his earlier life.
