+291 Some people believe in destiny, but others believe that what you do now is what determines the future. But if you really think about it, it all comes down to whether or not we invent a time machine in the future, amirite?

It's called determinism vs. free will... and has nothing to do with a time machine

I have a time machine in my basement... It just goes forward at regular speed.

Even if we built a time machine, it wouldn't affect anything in the past. There's only two theoretically possible modes of time travel, one can only make you go forward in time at an accelerated pace while only being affected by how much time you would have actually spent in the machine if it did nothing. The other is a bit more far-fetched, and requires cancelling out the gravity of a black hole, moving the beginning and end to gotether, and going through the hole in space-time it generates. The second option, even if it could work at all, couldn't take the user to back before it was created, because there wouldn't be an exit, because the tunnel didn't exist at that time.

Time travel wouldn't work because the second we discover it someone would come back and stop it.
