So let me get this strait. You are implying the impossibility of time travel? Is there any way to simplify the point that you're making? I read through the thread and, while I find myself intrigued, I find it a little difficult to follow. I kind of understand, but what I got (ADHD) was a visual of someone trying to go back to yesterday only to find that yesterday is not the same day as it was then and the instances in space-time have changed. Kind of like what happened to Trunks in Dragon Ball Z. He tried to go back in time to prepare the Z warriors for the arrival of deadly androids and stop the death of Son Goku. What he found was that the timeline he had reached was dramatically different than his own. Goku didn't get sick the same way, there were five unheard of androids and the Z warriors were considerably stronger on top of the fact that the androids weren't evil in the new timeline. It's as if he had only traveled through space, not time, to a universe greatly similar to his own. Now that, along with what I think you're saying, makes sense. But that's what went through MY mind. If you don't care, please restate your point in a different way. It doesn't have to be too much simpler, just different.
