Amazing. You either know more than he does, or he's dumbing down some things that are so complicated it would take years to fully grasp it. I don't get why people have issues with time travel. If you consider that time is done once it's completed, sure, then going back and changing things can cause issues.However the universe is far more complicated than that. There may possibly be an infinite number of universes. It may be possible to travel to a universe exactly like ours was 5 million years ago. How could you tell the difference between traveling through time and simply to another universe?Now things really get confusing once you start layering on the multiple dimensions that may comprise our universe. I'm tempted to vision our universe, time, and all possible multiverses, every single point of every pico second to exist as in single infintesimal speck. And that time only exists because we exist inside the boundaries that are time. It's late, and explaining concepts of time travel at 1 AM isn't easy...
I think this is what qiaohua was getting at: Take the basic example of going back in time and killing your parents. The "timeline" would look as follows: you're born, you build a time machine, you go back in time, you kill your parents, time goes on, but you're not born this time. It works perfectly.
So when your mom drives you up to the dam, and you float down the river on your inner tube, and she drives down to the park and plays fetch with Sparky while she waits 25 minutes for you - she traveled to the same place, but got there 25 minutes sooner, which means she traveled 25 minutes into the future. Science is amazing.

I miss the days when it was all about using DeLoreans.

Forget the rocket boots and robot wife, I want my TARDIS.

He he. I wonder how many will get the joke.
