Well everybody does time travel. The very fact that it took you time to read this means you are traveling through time. But as for going forward or backwards, that's a little different. If you go near a very massive object, say a black hole, the gravitational pull actually slows time (Modern scientist have to account for this when dealing with clocks on satellites, because the satellites actually experience time faster than those on the earths surface). Some think that if you got close enough to a black hole time would stop completely. Another way to slow time is to go faster in space-time. The faster you go in space, the less you are in time. Light, for example, never ages because it functions completely in space and not in time.
Now if you wanted to back in time there are some theories. The Tipler Cylinder is an infinitely long cylinder or tube. As it rotates it drags on the fabric of space time (as all objects do, stars, planets, you, me). But because it is infinite the spacial drag is massive, so massive that it in fact curves the cone of light (look it up on wiki). If you sent an object down the center of the cylinder at a great enough speed it would go back in time.
The other way to go back is to go faster than light. If an object goes slower through time as it goes faster, then when it goes faster that light it goes backwards in time.
There are some other ideas, but non of them or any of the ones I have said actually work for going back in time.
Impossible at any great extent, time is not spatial dimension, cannot travel at it, cannot travel at Narnia either, time is zero at photon, no matter can travel so fast however, time become slower but inertia become greater when increase speed, common matter cannot travel fast enough slow time much, only subatomic particles can do that.
Einstein's General Theory of Relativity allows the possibility that a practical time machine might be built. Such a machine would need to be able to create and manipulate black holes, and the technology needed for it is far more advanced than anything humanity might devise for hundreds or even thousands of years.
You do it every day when you walk against the rotation of the Earth. That causes you to go forward in time and when you walk in the reverse direction then time slows down from your perspective.

I wish!
My lesser wish is for a transporter like on the Enterprise, so I wouldn't have to drive or fly anywhere!
no, beacause to bring ur dad back ot life, youd have to reverse the flow of energy in the universe.
I doubt it, because there is no time to begin with/
Sure, I did it tomorrow.
