There is a theory that travelling into a wormhole, you could come out of the opposite end at another point in time. Of course, you would have no way of knowing where in the universe you travelled to. As for straight up time travel, you would have to build a machine capable of beyond lightspeed capability. However, the closer an object comes to travelling at the speed of light, the more mass it has. As the mass increases toward infinity, the more the force required to move it. In other words, you would need an infinite power to move the infinite mass. Obviously, this cannot happen.

actualy you can't travel back in time because it is impossible there are no time machine to do so and you can't make it. SO STOP ASKING A STUPID QUESTION

theoretically speaking, it is possible but physically impossible... at this time because we still do not have the technology to build a time machine, but when that time comes, we're already dead :p
