Time Travel

i have three ideas...

first of all, i think it could be possible because every tiny increment of time is called a now, and every time u make a decision it creates another universe. time traveling would be traveling between nows and between universes. if u made a decision to change the space time continuum, you would create a new universe and be stuck in the new one. so that makes me think its possible.

well, you know paradoxes are impossible. like the one where the old man goes back in time and kills his younger self. therefore he would be dead and not be there to kill his younger self. this is a paradox, and it is impossible. therefore time traveling is impossible.

but then again, ppl time travel all the time! thats what time zones are for!!!

That's an interesting theory. But by the same token, what stops us existing as part of another being's dream? Or part of a computer program to find questions and answers?

Anything is possible..and the (wo)man that finds the truth will be immortal and rich.

I've just found this topic!

Here are my thoughts on a few previous postings, such as they are...

There are plenty of theories for time travel which do not result in a paradox

What? While you are true in saying that all matter can be seen as energy waves, the frequency of a particle is directly proportional to it's mass multiplied by it's speed. If your car accellerates, it's overall frequency will increase, but it will not be pushed into a parallel universe.

As far as I'm aware, there's nothing in modern physics that states that it's impossible to travel faster than the speed of light. The problem is that the energy required to accellerate a mass rises exponentially, with the asymptote being at the speed of light, so in order to reach the speed of light, you'd need infinite energy. But, if something is already travelling faster than the speed of light, or if something has no mass, then I believe that it's possible.
But basically, any time-machine theories which involve acceleration to beyond the speed of light wouldn't work.

The 'fact' about us only using 10% of our brains is a complete fallacy. Activity has been measured in all areas of our brain. Most of this activity is either subconscious or unconscious, but it's still being used.

There is nothing to stop time travel to the future. As superng stated, you simply have to jump into a spacecraft and fly around really really fast. When you return to Earth, time will have passed quicker for everyone else, and so you will be in the future.
In order for this to be noticable, you will have to travel at unbelievabe speeds for some time, but it is possible. The trip will be a continuous journey, you will not 'jump' into the future. And there will be no way back.

This time-slowing effect is caused by a warping of space-time. Space-time is also warped by gravity, so in areas of space with strong gravity, such as near black holes, time-slowing effects are also noticed. But black holes are really really dangerous. And there are none nearby.

There is a paper here...
http://arxiv.org/abs/quant-ph/0506027
...which proposes a theory on how time travel to the past might be possible without creating paradoxes. The paper doesn't suggest how someone might be sent back in time, it just theorises how quantum physics could prevent paradoxes taking place.

Phew! Glad I got all that off my chest.

As much as I like the idea, it will NEVER happen!

What you mean like in Men In Black 2where they open a door and the whole universe is inside a train locker?? Interesting, well I'm open to the idea.

I just want to apologise to the people of this topic. Looking back on what I wrote here makes me ashamed, I cannot believe I ever said it.
