Thanks for the clarification. I should say I don't believe you can time travel and that there is only one flow of time, unless alternate universes exist, but I don't think they would exist in the way we think as in being a duplication of our world with just choosing door A instead of B for every possible decision, which leads to an infinite amount of possibilities. We could only suspend our progression of time by moving at the speed of light.

Whatever happend to my post? Good thing I ctrl+V it, before saving my edit.
repost + new:
No, decreasing entropy will not change the flow of time. Entropy just happens to increase with time, time does not increase with entropy. There is only correlation not causation.
People have also said that one can move bakwards in time by traveling faster then light (tought experiment!). But when speeds faster then light is plugged into the equations of special relativity you get imaginary time, not negative time.
However! If you know the logic behind relativity, you'll come to the conclusion that moving faster then light means going backwards in time. (You see a forward-moving lightbeam moving backwards).
To me, this implies that either the theory of relativity(time) or our understanding of it, when it comes to speeds greater then light is, wrong and has to be improved.
Not wrong as in: "Theory is crap and good for nothing".
But wrong as in: "Theory holds for everything we know except in this physically impossible state, where logic goes against theoretical predictions".
What this improvement would be, I don't know. But I know Stephen Hawking is very keen on imaginary time to explain singularitys.
incomprehensible after the first half dozen post's
If you could go back in time and kill your grandfather, something would have to stop you from killing him.
because if you killed him before your parents birth, you would never exist to go back and kill him (we already established this as the grandfather paradox)
If this is the case then there is no such thing as "Free Will" as everything is per-ordained. If everything is per-ordained then that proves that there is a higher power and the universe was created for a purpose and this would mean that some god like being created everything. Now since all religions are based on a belief system with out the actual ability to prove anything, Then surely it stands to reason that by proving that the universe was created with an intended purpose that if you where to go back in time to attempt and ultimately fail at killing your Grandfather to some unknown effect or reason that all religion is false.
As the Moon is 400,000km from the Earth and the speed of light is 300,000km/s the time taken for light to travel is about 1.3 seconds. If you were looking at a clock right next to you, and one on the moon, the one on the moon would be 1.3 seconds slower. (There's a bunch of other things that can change the time of a clock as well, such as gravity).
Imagine that if you looked at the moon with a telescope, then traveled several times faster than the speed of light to the moon, you would have seen yourself at the moon before you arrived there.
Or, if you were several light years away from a planet, and traveled towards it faster than the speed of light, you'd see that planet "rewind" because you're travelling faster than light.

I've always tought about time traveling and stuff, read all the probably causes and paradoxes for it not to work and i think i came up with something plausible.
Scenario: The time machine is built and it's fully functional, yes, but now, no one in the project or that even know about the time machine will ever be able to ride it to the past, because the mere tought of changing something would lock you in the Grandfather paradox.
Passenger: Someone smart, fit, that has been tested to be optimal and it's in trainning for something, a project, he knows he may be called someday for something big that when it happens he's to leave his family and friends forever, someone brilliant enough to not know anything yet when he gets "there" and realise where/when he is, to act, to estabilish himself and think, ok, they sent me to the past, i know some shit that could be changed and since i was sent to the specific time, i must do. ie. Hittler timing, ww1 events, 9/11 and some other catastrophic event.
Now, bear with me, the guy must not know anything about his "calling", where to, how to get there and what he's supposed to do.
Anyone get my drift? Any suggestions to improve our little paradox fixing?
Sorry for bad english. =D
Your words are like your intestine, stinky and loaded with danger.
That's not really what they're talking about with time dilation. They're talking about time ACTUALLY moving slower, rather than the difference in time between when something occurs and the light reaches you.
So if you have a radioactive isotope with a half-life of 10 minutes, and you have it approach the speed of light, the half life of that isotope could last centuries from the perspective of someone on Earth, even if the Isotope hasn't moved very far (let's say it's in orbit around something very massive nearby). It's time ACTUALLY slowing down for that object relative to slower moving objects.

Or a yawing hole in a battered head
And the scuppers clogged with rotting red
And there they lay I damn me eyes
All lookouts clapped on Paradise
All souls bound just contrarywise, yo ho ho and a bottle of rum!
There is also the one theorie that events must happen or else something greater could happen. Like if you went back in time and stopped a bus crash that killed 10 people you might have saved them 10 people but doing so causes 10 other people or at most a lot more then 10 to be effected.

I'm not going to do your research for you and dig up any sources but I can try to explain. The whole theory of relative velocity time dilation is based on the fact that the speed of light is a constant and you can not exceed it. When an object is moving at speed X and it's emitting light that obviously moves at speed of light we get a problem. When you count in the speed of the object and the speed of light we get a speed that's supposedly faster than speed of light, which is not possible (theories of relativity). That means that for the described situation to be possible the actual frame of time in which the event happens has to "move slower", hence, time moves slower the faster you move.
There's also evidence supporting this if you don't believe the theory. An atomic clock inside a satellite of a space station counts time slower than same kind of clock at the surface of earth which is explained by the faster speed of the unit in space. Gravitation also has an effect.

Yep, that is correct *shrugs*
However if you view time as a dimension or a simple human construct to make sense of entropy/energy transfers and their rates, the conclusion will vary, one allows for time travel (if its a dimension you can supposedly move either way) if it is an illusion of the mind there is nothing you can do aside from slowing down or speeding up natural processes which is quite different from the idea of time travel.
The clocks differences and time dilations all can be explained by difference in rates of decay/energy transfer, and if that is the case then again, calling something going really fast time travel then you have to call your fridge a time travel machine, same principle (slowing down processes) different means (removing energy vs gravitational effects on matter)

This is correct, steven hawkings also touched on the subject and used an example using a train traveling at the speed of light, so anyone riding the train will also be traveling at that speed, now if you were to move forward inside the train while already at the speed of light, the universe cannot accept that (apparently you cannot go faster than light) so you will get slowed down. http://www.dailymail.co.uk/home/mosl...#axzz2JiUYMtTG
Time travel is a bad subject because nobody knows dick about it, so at best you can theorize.
Everything is a manmade construct, since we are humans, and we choose to call it reality. It makes no sense saying it's 'just a manmade construct'.
You can definitely go forward in time just like you go forward when you start walking, you can be timeless even, if you were a photon.
Of course time exists. Do you think there was no passage of time until humans evolved? Because the universe is 13.7 billion years old.

This statement is prima facie absurd.

Clearly the billions of years prior to human existence is completely imaginary.

There's no such thing as "only a theory" in science.
This is flawed reasoning and I'll explain why by analogy. (Side note: I don't mean that an analogy is proof of anything, it was just the simplest way to explain how I think on the subject of the grandfather paradox and similar)
Let say you put a ladder up against a roof and climb up. Once up, you push the ladder over. Even thought there's no longer any way to get up on the roof, you are still there.
Now think of the ladder as the chain of events that led to your inventing time travel/going back and the roof as the act of saving your loved one.
Even though there's no longer any need to time travel and save them, you still did.
