Before 1969, how many things had you seen go to the moon?

2. Silence! You are bringing logic into this! That's heresy!

3. Time isn't matter or energy therefore it doesn't exist, you can't change something that isn't "real".

Time is a system we made up to help us, not something that was there and we discovered it.

Your argument fails to hold water. Time is another coordinate through which we can specify something's location. As two events cannot occur in the same location, they must either be separated by either spatial distance, time, or both. Time does exist.

5. We'll, i was saying that if time travel DID exist, it would'nt be possible to do anythign with it. But as some people have siad, time does not really exist. I suggest this if anyone is interested in this kinda thing.

6. True, true. One of a few things will happen: a) the change will cause the alternate universe to branch off; b) the universe will be stuck in some sort of infinite loop; c) causality will 'force' you to instigate the exact events that you tried to prevent, and therefore your time-travel becomes integral to your own history; d) something completely different. Regardless of whether you view time as a change, or a series of events, or some other way, it still rather distinctly separates events, and so does exist... That book looks good, by the way.

Cheers

You time travel everyday... Come on, km/hour

If you are going to say that make sure you say it in a way that no one can correct you!

No I mean it's capable of happening, but the stress of all of it on the brain or whatever is just beyond anything that we can achieve as humans.
Some say that we only use aprox. 12% of our brain, so I don't think that I braine can't handle it.

Yea that's actually a myth.

Doesn't it depends on what we do

Anyway, time is a funny concept. Why? Well, in the Chocomilkyway, if they had a telescope to see earth, they'd probably see dinosaurs.

Also, there's all this crap about 'Spirit, soul and body'. But it's actually just body =\

11. Studies have shown that objects traveling at a faster speed travel further in to the future. For example on the international space station, astronuats are (a really small amount of time ending in a six is all i can remember) ahead of us.

You can demonstrate this to yourself by getting two clocks that are incredibly accurate and can recognize very small amounts of time. Synchronize them, leave one at rest and drive on the highway somewhere with the other one. When you return, the clock you left at rest will be behind the clock you took with you.

EDIT: Don't drive on the high. hehe.

12. Sounds like if I was to live in space everyone on earth would die by the time I die, or even before (everyone my age).

If you take a bit of bread, and travel to the sun at lightspeed, and come back, everyone's a lot of older but the bread, and you, just are a little bit older. If you survive the sun of course.

14. I don't see how a machine would be able to identify a time in space with our time, it wouldn't be able to identify something physical with something that doesn't exist.

15. The twins paradox doesn't seem particularly pertinent to me. The reason I say this is that you haven't gone forward in time per se (at least any faster than usual from your perspective), you've just experienced a longer period of time compared to your stationary observer.
