Is time travel possible through breaking the speed barrier?

[Aidee]

I know we can travel to the future when we exceed the speed of light, but wouldn't that just place us in a moment of time(What is time anyway?) ? I mean, the people in the past have already died, their causes have effected. If we were to travel to the past, we wouldn't see people in the past. And if we travel to the future by going around space, we wouldn't see people from the future.
So how would traveling faster than light place us in an environment in the future/past when we would just be taken to some point on the grid of space?

first off, we can't go faster than the speed of light. (if you're referring to the recent experiment involving neutrinos, the speed was confirmed to be in the margin of error, meaning it didn't happen.)
anything with mass takes an infinite amount of energy to reach the speed of light, an amount of energy that does not exist in the universe.

however, your time is affected relative to other people no matter what speed you're going, it's just negligible at slow speeds. also, it's not that you travel into the future, it's that your time, in your reference frame runs slower compared to a person in a frame of rest. so, if you go fast enough (which is much faster than we can currently go), your time will run much slower while theirs stays constant, which will seem like you're moving into the future.
so potentially, you could meet people in the earth's future.
but in reality, time is relative, there is no specific future, past or present. it's all dependent on your frame of reference, hence theory of "relativity" this is just one way that time and space are mathematically linked, which is where the term space-time comes from

going back in time is a different thing all together. the only part of relativity that discusses the possibility of going back in time involves wormholes which currently goes over my head.
