Umm, if you can break the Cosmic speed limit, you go back in time. Nothing can go beyond. A tachyon spends iit's lice going I reverse. They can never slow down to the speed of light, as such, we can not reach that speed our selfs. However, you travel faster through time as you are closer to a more gravitational dense object. You basically life longer orbiting a black hole, standing next to a giant Egyptian pyriamid, or the like compared to someone who never goes near an object that is more gravitationaly dense than a television.
Also, if you are traveling the speed of light, and you throw something, or move in the direction (I.e. run on a train going that fast and it slows every thing else down by compression. It is the universe's way to prevent backwards time travel. Travel to the future I'd possible and quite easy, if you have the knowledge and materials. Just good luck with the black hole...
