Talk:Grandfather paradox

Orson Scott Card dealt with this in his book Pastwatch: The Redemption of Christopher Columbus. I'm not sure if his explanation is worth repeating in the article since the book isn't widely-known, but I will explain it somewhat here.

The moment you travel to a previous point in time, all time past that point ceases to exist. You (and anyone traveling with you) continue to exist physically, but you are not "tied" to the future in any way.

After looking at what I've typed I realize it's close to the parallel universe theorem, but Card's method was logical and well-written. Goatasaur
