Comeon, time travel? Sure, its possible, but whats the point? If theres anything we learned from the Back to the Future movies, its that time travel can only have bad consequences!

But seriously, time travel into the past could not possibly work because your being there would inevitably change the future youre from. IMO theres a "tree" of events, any time multiple things are possible that branch splits, so theres a different universe for each possibility. So, you go down the tree, means you change events, means you go up a different branch. So, if you were to travel into the past, you could never return. This scenario is demonstrated (vastly simplified of course) in Back to the Future 2. However, using this model, travelling back in time (and the paradoxes implied) can be possible. It also explains why we havent met any time travellers yet.

Why would you want to travel in time if you knew you were going to change it? What use would that be?

I'm more for the idea that we should accept reality as it is, with all its evils attached.

Bah, there's nothing more annoying than a man who has no regrets

It's not a matter of no regrets. I know exactly what I would do given the opertunity. The problem is that I worry that I might make things immeasureably worse.

Well, you also don't know what bad parts of history, or even your life, have created good parts of the world, or your own personality; the whole concept of going back in time obviously comes from the desire to fix things you or others have done wrong (to go forward is another matter), but sometimes it's quite hard to see the true ends and purposes of our actions... instead of trying to wipe our history clean, we should accept it with all the stupid mistakes and terrible atrocities, because we have no idea what purpose they may have had.
