I don't believe time travel is possible. It it was wouldn't we get people coming from the futuer coming to tell us about some disaster and how to prevent it? Or wouldn't we be going back to stop them. Humans like to screw things up, it's in their nature.
That depends on the nature of time itself. It's possible that we won't see any effect until someone actually comes back in time. More easily understood, it's possible that it has happened and we've not noticed it (Because it's the natural continuation of our timeline, as we see it.) or it splits off into alternate timelines.Quote:

I don't know how to word this, but it's very possible that there is no additional time to the time we experience, and time is always moving with us, so it's therefore impossible to travel back in time, or forwards in time.
And also keep in mind that by going back in time (not forwards), you'll essentially create a copy of yourself. And the old you, back in the time that you're travelling to, will probably do the same as what you did back then, so no, you probably won't be able to ask those girls out if you don't want to give them a heart attack.
I heard a discusion on tv about this not long ago. The scientists there said that the light from the headlights would still travel at the speed of light, not double the speed of light or anithing like that.Quote:
What happens if your travaling at the speed of light and turn on your headlights?
Correct as light cant be propeled forward, if you run and 2 MPH and throw a ball at 3 MPH the ball gose at 5 MPH but that is not how light works so it would only travle at the speed of light.Quote:

What happens if you go at the speed of light and turn on your headlights? You die, if you are going at the speed of light in a veachle that has headlight, I am guessing you hit a tree a long time ago.
It's easy. Just get the lunar whale, go to the moon, stay there for a while, and BAM. You gots yourself a ticket to the future! Go back to the earth, and time machines will be all the rage. Then go back into the past, and you find that you screwed yourself over, because upon going into the past, you changed the future and erased your own time. Thus making you come from no-where. You will have to live alongside your new twin as...
THE TIME BROTHERS!
You ran out of ideas halfway through, didn't you?
Yeah. :mad:Quote:

I'm a loser so I wouldn't time travel. Plus, you know, you could screw up history and your life majorly.
