Question

No i didnt gimb . And even if i had i wouldnt of got the same answers.I didnt ask out of making a point from my myself, but to get the ideas of others.So there friggin smarty pants.

Answer 1

Time Travel! A great subject to talk about and an easy way to 'blow our minds' with different theories!

Here's a couple of ideas:

We live in the present, so maybe only the 'present' and past has happened. That means the future is yet to happen, so the time machine is yet to be invented and come back to the present - or what would become the past.

Maybe time machines can only visit in a 'viewing' capacity and not interfere with the past. Can you imagine the damage you could do if you could alter the past?!

There's always this same problem: What if you build a time machine, go back in time and do something that prevents you building the time machine in the future? The time machine doesn't get built. But that means you don't go back in time. So you don't interfere with the past. So the time machine does get built. But then you go back and prevent yourself building it.... And so it goes round in mind blowing circles!

Answer 2

achievable motives: a million. whilst the come again the time circulation branches authentic right into a separate course, in order that they become a sparkling time circulation it is parallel to our very own. That streams destiny could be specific from our destiny. 2. There have come and are right here, yet in such few numbers we don't comprehend them. 3. The earth is on no account a similar situation in area. If somebody 1000 years from now is going lower back in time to now, they do no longer become on earth. whether they emerge as the situation the earth could be in a 1000 years from now.

Answer 3

The impossibility of time travel is answered by your question.
A time machine would branch through all eras past and future so we would have encountered them continually.
I would sure have one and I would have been all over the space-time continuum.

Answer 4

Yes, time travel is possible; but only through wormholes in space which would crush a human. If someone has tried to visit us from the future, they have been crushed to death.

Answer 5

Okay, the problem is the lack of evidence of a visit from the future.

Anyway. Assuming that there's no existence of multiple timelines which lead to parallel universes, then the whole timeline can't be change.

Answer 6

Perhaps they already have...
but because of the "Butterfly Effect" they are forbidden or disciplined not to do anything more than observe, therefore, because of the lack of interaction between themselves and anything within our time, we would never be aware of their presence or that we have even been visited by travelers from our future.

Answer 7

simple, if they where to disrupt the past, then the inventions nessicary for time travel to be possible may not come to pass, or somebody might not meet at the right time, and cause a completely different time line, where everything is mess up

didn't you every see 'Back to the Future"?

Answer 8

Time travel is impossible. You can in a sense go forward in time by travelling close to the speed of light, but you run into other problems and its impractical.

Answer 9

Perhaps because the time machine, when built, will only take you as far back as the moment it was built and it is not yet built.

Answer 10

I believe you have answered your own question. It is not possible to time travel, nor will it ever be. Perhaps time is not tangible enough to allow that.
