Re: Timetravel
 

If you get ahead of everyone else by "time travelling", then you would only be ahead whilst you were moving at that greater speed. As soon as you slow down back to a more "normal" speed, you would lose the advantage in time that you had previously.

So it might be possible to move faster through time, and whilst you were doing so anything you did would be noticed by people moving at normal time, a little while after you did it.

But then when you begin to slow down, the difference in time would be reclaimed, until all is normal. Though you would have aged faster than others, you would stop doing your actions ahead of everyone else.


Travelling faster than the speed of light is impossible. If you went faster than it, then presumably you'd cease to exist, as you'd be moving faster than the image of your body.

Re: Timetravel
 

Practically you'd need to be in space to do it, because to accelerate at such great speeds would require a lot of space. You would essentially "speed time up", when you stopped you may be 2 minutes ahead of the time you left at, when it had only took you half that time.

Re: Timetravel
 

It wouldn't really be speeding time up. Time is a constant. In fact, trying to define what time actually is is quite hard. Measuring it is easy, as we have managed to do that, but trying to find the speed at which time actually moves, is a problem. If solved, then it would open up a lot of windows into the field of "time travelling"

I guess the way to find it's speed would be to measure the rate of the expansion of the universe over a certain distance. However, this would be hard, as the area would need to be large, very large. The problem with that is that finding somewhere big enough, which is totally devoid of gravity for the whole distance.
Another problem is that you can't get a set distance, because you can't look ahead of the universe and its path of expansion.

Re: Timetravel
 

It may be a constant, but to time travel you have to be faster than time, that creates a whole new set of problems really I suppose. It's all very theoretical stuff and we really still have no means or ways to measure time or any variables it may have.

Re: Timetravel
 

This to bound to get very confusing,time travel always is.

Re: Timetravel
 

Exactly it is just like Grimme says, the only thing we can really do is guess and discuss.

Re: Timetravel
 

time travel is rubbish. it's fantasy, existing in science fiction only.

Re: Timetravel
 

If we or you could be exactly the same for a second, you could time travel, but as long as you have the slightest change per a second, you cant....

Re: Timetravel
 

Lets just summarise a little.

Most people think timetravel is impossible, some think it will be in the future, and some don't think time exists.....

I was having a discussion with a friend earlier on today about this topic, and here is what we conclused: If timetravel is possible, then we would not know. - In theory it wouldn't matter.

Think of it this way, if you had a time machine, and were to travel to the past, you would be changing your own existance. Thus, you wouldn't actually arrive at the past, you would simply be erased from time.

Demo: You and a few friends build a fully working machine and plan to go back intime (say there are five people) - this machine can only hold three max, so three people get in, and decide to travel back in time say 500 years. Going back in time would corrupt the future as you know it, thus, you wouldn't actually arrive in the past, because (if you did) you would change the future. The three people that got in the machine would simply never be seen again, and the other two people that were left would simply believe that there friends were trapped in the past.

Either that, or the time machine (from protecting 'time' wouldn't actually work)! This being the case, you can't travel in time as you would simple change your life and end it.

As for going to the future, that would again be somewhat impossible, as if you went to the future, it doesn't yet exist, so how would you get there? thinking of it logically, if you leave your time to venture into the future, what could have happened if you didn't go would be the future, you going into the future would work as it doesn't exist

This theory works better for going back in time (makes more sense than the theory of going foward), but the general jest of it, is if you go back to a time before you were born, you wouldn't actually get there.

Edit: Also, the theory that FT said, we were also discussing that, and again, came to a conclusion, i understand what FT is saying, that being:

Earth has a gravatational pull on us (humans and what not), the sun has a gravatational pull on Earth, and in the center of this Galaxy there is a massive black hole - of which is having a gravitational pull on all the Suns. With this, there is more than likely something in the center of the actual 'universe' that has a gravitational pull on all the galaxies that are scattered about - this would be a good place to assue the big bang took place.

So, time does exist, it just so happens that it is different throughout different parts of the universe

Re: Timetravel
 

No you would have aged less than those moving slower than you, to you less time would have gone by than for those you left behind, so when you slowed down, you would see that more time has passed for them and everone would be much older then when you first started your journey, you wouldn't notice this until you slowed down and saw that to everyone else more time had gone by than what you experienced.
