Time should be treated as if it was another dimension. To find someone in a helicopter for example you need to know the latitude (dimension 1), longitude (dimension 2), altitude (dimension 3), and the point in time (dimension 4). See each piece of matter can only be at one latitude, one longitude, one altitude, in one point in time.

What you're saying has been documented, but not faster than light travel, since it's impossible. Zero mass particles in a vacuum will always travel at c, like photons...however, you can't accelerate a non zero mass object to c or beyond c because it requires infinite energy. So, we don't have to worry about this at all. Absolutely everything in the universe that is moving undergoes Time Dilation, specifically because any such movement alters your frame of reference. It can be described most simply by 1/Sqrt(1-v^2/c^2) as the change in time, where any change in v will cause reference change at some level. This happens because of the energy you are required to gain to produce this change in v, where E=mc^2 also abides by the same reference frame law (E=mc^2/Sqrt(1-v^2/c^2). This is not something that is disputed, so your friend is absolutely right. The phenomenon is used in practical applications as well - for example, in image projection in things like TVs. Because the electrons used to produce these images move at relativistic speeds, we have to correct the image for Lorenz contraction which would distort it. This phenomenon isn't Time Travel though, and I still doubt it's possible. <_>

But 'time' is just a concept created by humans to make their lives more efficient. 'Time' to a human is much more exponential to us than to a tree.
If you take an intelligent being (other than humans making this completely hypothetical) and give it a watch. Now, this being's average life span is... let's say 1000 years (years being a human measurement). That being, we'll call it x, looks at its watch and sees the minute hand tick by. The minute hand to this being represents much more than sixty seconds. Because the average moment for this being (moment being a particular situation) is 6 [human] months than a minute takes much less time up. It would seemingly fly by. In conclusion to this rant, time itself is simply an inaccurate measurement because it was created using the average span of one mind (being humans). |

Did you even read my post involving the distinction between time and Time?
To something that lives 1000 years, our use of seconds as a significant span of time might seem silly, but that doesn't mean that one second for us is actually a different length of time than it is for them. Time is Time and passes at what amounts to a fixed rate for everything. How we choose to set up time to understand how Time is moving is arbitrary and human invented yes, but that's like saying that we invented the word "tree" so there's not really such a thing as trees. You can say there's not necessarily such a thing as a "tree" insofar as "tree" is just a word we apply to a bunch of things with the characteristics we've defined as "treeness" but you can't say the physical object isn't still there in front of you no matter what you call it. We may say "That's a cat" and someone who speaks french says "c'est un chat" and we're using differenet terminology, but we're still referring to the same actual object. WHether you measure in what we call 'seconds' or what we call 'months' as your shortest length of time that means anything to you, Time is still Time no matter what time system you apply to it. Do you see what I'm saying? Quote:
Moving faster than the speed of light is just the most -efficient- form of "travelling to the future" because you get a rate better than 1:1 of subjective time bjective time. So just because we think going faster than c is impossible just means the most efficient manner of such travel is closed off to us.We've already established that miniscule differences already exist between certain people and everyone else, so the thing is happening, but I do agree that while it appears like time travel to the person doing it, the effect to almosty everybody else would be that the person was moving only very slowly, not that everyone else was somehow fast forwarded. |

Time? The only way we can measure it is by using a timepiece, but we still can't see, touch, taste, hear or smell it. There are no particles that constitute time (as far as I know). We invented a system, based on the moment from where the sun rises (or sets) to the moment where it rises (or sets) again. We divided that into 24 hours, and then minutes, seconds, etc. What if there was no day and night cycle (of course life would not spawn, but let's say it's possible)? What if there wasn't an impression of movement, of change due to the degradation of things and the spawning of new things? Well, humans wouldn't know what "time" would be and probably never would of though about it. Of course, this improbable image is just to explain my point, but I think you can understand.

Can you hear length? Smell depth? I'd argue that you can -see- time as easily as you can see the width of somthing. Why does it have to be measurable by -all- senses in order to count? Quote:

Anyways, I suggest we stop getting away from the main subject. Clearly, devonin, you understand my point and I don't think neither of us will be able to change each other's mind so let's not waste our time.

Why does something have to have a physical presence to exist? You can't "take" or "pick up a piece of" gravity either, but I'm pretty sure that's real.

Hmm, you do make a point. I'll think about it and come back to you.

I'm leaning towards Devonin's explanation for this one.

Gravity and energy are a result of the three first dimensions. Without them, it would be impossible to have an object attract another. They are thus contained within those dimensions as a physical phenonmenon.

time travel is defenetly possible because the more you think about it the closer you get to it, like a dream its all a manisfestation of thought. its like the human race for instance think about in comparison to a animal. they use there instincts there natural instincts to survive ,humans thoe we once had natural instincts,but have evolved not by our survival skills in the nature but in the mind ,why cant any onther animal build a house out of bricks ?because they are what at one point made it possibal for our spieces to excist it all makes sence the more our spieces multiplys the more the brain will evolve the smarter we will be ,thus making time travel possibal minus the fact that with so many people and the more to come and the more "free" the world gets equals more resources a shortage of water and a mass suicide of our spieces so unless you can see the pritty picture there is no use meddling in where theres no point to do so.

So according to you everything is possible in time...This is simply something people say to motivate people. Time is not a variable as mentioned many times before me, it is simply a perspective, we just see it as a variable because we keep time.

Second, humans still have instincts, I'm not sure about you but whenever someone is threatening me physically, I feel the urge of getting away or wanting to be in a safe position. Third, the reason why most animals can't build houses isn't because they don't have the intelligence (many animals build nests, dig holes, in other words, anything they can do to take shelter), it's because they don't have the physical capacities. No hands with opposing thumbs, no correct position of the back, etc. Fourthly, more humans doesn't necessarely mean smarter people. Humans became intelligent because somewhere along the line of evolution, they changed their diets, adopted a new posture and migrated to a place where survival was not the only concern. It took thousands of years, evolving from apes to what we are now, gaining one bit of "intelligence" at the time until we've become what we are now. But anyways, your example is irrelevant here and has nothing to do with time nor time travel.
