OK lets discuss time travel, and the possibilites of time machines. Speed+Time=The Speed of Light No matter what the first 2 are, they MUST equal the speed of light. It has been proven that as something moves with greater velocity, the time relative to it slows down. So in theory, time would eventually have to be negative if the speed was great enough. The speed of light is roughly 186,000 Miles per second. As your speed increases, time slows down, correct? Acording to this law, if you were at the speed of light, time would = 0, as 186,000mps + 0 = 186,000mps(speed of light). So if you could get to the speed of light, you could stop time.(relative to you at least) But what if, you could go even further beyond that speed. Time would have to equal a negative number(going back in time) to equal the speed of light. Lets say 200,000mps+(-14,000)=186,000. You would be going back in time correct? If this is possible, we would need an immense amount of power, and a way to keep a human being alive while going so fast, but if we passed these limitations, acording to the math above, is time travel possible?
