Time travel is possible and what's more, its already been done. Sergei Krikalev is known as the greatest time traveler in human history. This Russian cosmonaut holds the record for the most time spent orbiting Earth. A total of 803 days , 9 hours, and 39 minutes. During his stay in space he time traveled into his own future by 0.02 seconds. Traveling at 17,500 miles an hour, he experienced time dilation. http://www.universetoday.com...#
Definition: Time dilation is the phenomenon where two objects moving relative to each other (or even just a different intensity of gravitational field from each other) experience different rates of time flow. http://physics.about.com...
Phenomenon: a fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question.
One day we will be able to use time dilation to jump ahead much farther into the future.
Any significant time dillation only occurs at speeds close to the speed of light. Accomplishing this requires extraordinary amounts of energy which is impossible for humans to supply. It is impossible according to current physics to move backwards in time. Therefore time travel is not real, since we can only theoretically travel forward in time, but we cannot actually do so, nor can we travel backwards in time.
Just because we can't go into the past, doesn't mean we can't time travel. Con says for any significant time dilation only occurs at speeds close to the speed of light. But time travel does not have to be a year into the future, or even a day. As I have already shown, someone has went into the future by .02 seconds. That technically is time travel. We don't need to go at 299 792 458 m / s to travel through time. But to go farther into our future, we do. Time travel has happened, even if it was extremely small.
If you use time travel to mean the passing of time, then technically we are travelling through time right now. That is not what the the term "time travel" describes. You have purposely misrepresented the concept of time travel by misinterpreting the term "time travel" to mean any travelling through time. If that was the case then we are currently undergoing time travel at this very moment, I am travelling into the future, as are you. The intended meaning of time travel is the ability to travel to arbitrary points in time in the future or past. If your time travel is limited to between an extra 0.00 to 0.02 seconds into the future (only with a huge amount of energy and for brief intervals) its not really time travel.
Therefore my original arguments stand and time travel is not real.
