### Time travelling is not posible :(

http://en.wikipedia.org/wiki/Time_travel

If one were able to move information or matter from one point to another faster than light, then according to special relativity, there would be some inertial frame of reference in which the signal or object was moving backwards in time

http://en.wikipedia.org/wiki/Quantum_computer

http://en.wikipedia.org/wiki/Quantum_entanglement

A 2008 quantum physics experiment performed in Geneva, Switzerland has determined that the "speed" of the quantum non-local connection (what Einstein called spooky action at a distance) has a minimum lower bound of 10,000 times the speed of light. [13] However, modern quantum physics cannot expect to determine the maximum given that we do not know the sufficient causal condition of the system we are proposing.

Where is a mistake? Because if there is no mistake about that, then time traveling is possible and is almost reachable by today's technology.

Logically, i can't see how it can be possible. Time is an invention of man, the "progression" of matter isn't, we just use time to measure it. "Turning back time", how can all matter possibly restore itself to a previous state? Likewise with the future, but with something that hasn't happened yet.

### Re: Time travelling is not posible :(

Oh man, I almost 'gasmed when I saw this thread.

I have so many ideas on time travel, quantum mechanics/physics, dimensions... This is one topic I don't discuss in text, however, because it takes forever to get my ideas across >_<

Assume that everything I say is or could be a lie.

Besides the masses of paradoxes that would be introduced, I don't see how all matter can just be reverted to a previous state. I have my own ideas of how matter progression works, but timetravel seems quite impossible to me (as well as multiple co-existent realities).

This explains my position exactly.

As do most of your guys' posts

I can understand pseudo-teleportation in which we can get from one place to another in a miniscule amount of time, but real teleportation and real time travel does not seem possible to me.

Time travel and teleportation are all good ideas, but don't you think by the time we can put together something like that, then Microsoft would already be hovering around the 3000's?

However, I do believe that if you can get above the speed of light you do start to mess up time. For example, time on an airplane is a couple of milliseconds behind time on the ground.

As for teleportation, you can send a fax can't you? Once it's broken into a stream of electrons. . . (Even though if you don't get rid of the original it's more like copying. :p)

In a fax that data still has to travel.

Anyways, I sincerely hope that if anyone discovers time travel in 10,000 years, they'll be kind enough to travel back in time and tell us about it.

A fax is more like what you said: psuedo-teleportation.

That will result in the grandfather paradox. If they come back in time to help us invent time travel, by the time they create time travel it will have already been created meaning that they don't create it, so they never come back and tell us about it, meaning we don't have it. Confusing, I know, but true.

String theory speaks about 10 dimensions, do you realize all possible universe endings? Now take that as a single point. Now realize another possible endings for universe with different configuration and take it as another point, make a space between those two points. Do you realize all possible configurations. Crazy thing... but out universe might be SUCH big.

About quantum mechanics, how it could be faster then light (entanglement) ? How a matter could be in many different positions at the same time (superposition)? How a matter could act like a wave? (double-slit experiment)
Strange things are going on in quantum mechanics.

First, we can speed up time, so in essence, travel through time at a rate faster than what we consider normal. When we reach certain speeds, relative to that position, time speeds up.

Second, traveling backwards is impossible. There are innumerable reasons why including math.
