The way I have always understood the way "time" travel would work is that you can speed up, or slow down time, but you cannot travel into the past. History has been written, and can't be "unwritten", but you can slow time down by speeding yourself up or speed time up by slowing yourself down (theory of relativity).

For those of you who know not what I am speaking of,

The faster you get to the speed of light, the slower time progresses, at least to you. Once you have attained the speed of light, time would seem to stop completely. To speed time up, (to travel into the future), you would have to do the opposite, which would be to slow "the speed of light" down around you, while retaining the normal speed of light in the surrounding area, thereby making you attain a much lower speed of light, you would appear to be comatose to the world around you, but it would all pass in a blur.

And here are some more problems. The closer you get to traveling at the speed of light, the more mass you have. Using Einsteins E=MC2, (energy equals mass squared) and remembering that Light is a form of Energy, you would begin to have energy course through you, causing you to heat up, and make you luminescent. The closer you get, the larger, the hotter, and brighter you get. So, if you were to attain the speed of light, three things would happen, in stair-step: 1.) As your mass increases, you would occupy all points in the universe simultaneously, 2.) the second your mass squares its initial self, you become pure energy, 3.) and become energy in light form.

So to effectively "Slow time" you would have to accelerate and decelerate yourself to and from the speed of light like a strobe light, assuming of course that you could be turned from energy back to mass, and could survive the heat you would generate. If you were to try to go backwards in time, you would have to go faster than the speed of light.

To travel forward, you would have to do the exact opposite, you would have to "slow down". For example, say you were to make a chamber, in which you could control the exact speed of light on a scale. You enter said chamber, and operator outside of the chamber slows your relative speed of light down to say 5 mph (meaning light would only travel at 5mph), and you on scale with the speed of light would slow down accordingly. The speed of light outside the chamber would still be 670,878,000 mph

(math for this is 186,355 miles per second, x 60 seconds, x 60 minutes = 670,878,000).

So, the light inside the chamber is:

5mph (approximatley 5/6,708,780 of the "normal" speed of light")

and the light outside the chamber is:

670,878,000 mph.

Now for the "fun" math.

One second of time inside the chamber, (6,708,780) times one second of time outside the chamber, (670,878,000) = 4,500,772,908,840,000.

4,500,772,908,840,000 divided by 186,355 (light normal speed per second) = 24,151,608,000 times normal time.

So, 1 second of "slow" time would be equivalent to 402,526,800 seconds of normal time, or 6,780,800 Hours, which, if my math is correct is 766 years. And that, is ONE SECOND.

and problems with this are:

The slower you get, the more mass you lose, as well as energy. So you would end up 5/6,780,800 of normal mass, and energy accordingly. Meaning, you decrease, but not in density, and would be 5/6,780,800 of normal body temperature.

I think my math is right, if not, lemme know where.
