Will time travel ever be possible?

We already know how to time travel to the future, we just can't feasibly do it yet.  It just involves going really really really fast (99% speed of light) and you travel forward in time!  You can also stand next to a really really really heavy object and you'll travel through time slower. 

Traveling to the past is another story.  People thought you could do it through wormholes but if you could travel to the past then you could create a paradox.  The universe doesn't like that so it does every thing it can to stop you from traveling to the past.  If a wormhole was opened up that was large enough for you to travel through, it would instantly create a feedback radiation loop that would instantly destroy.  That's the universes way of not letting you create paradoxes.

What we "see" in the present though really happened in the past, as what we see is just light bouncing off an object and reaching our eyes right?

So what if you could travel faster than light, say move away 1 light year in the blink of an eye, and have a powerful telescope that could focus back on the earth, wouldn't we be seeing what happened a year ago?

That theory fails simply because you can't travel faster than light.  It's just one of those laws of the universe.

Hell, I don't believe you can even travel as fast as light.  Why?  Again, because the universe doesn't like you breaking rules.

Pretend you were going 99.9% the speed of light or even the speed of light, what would happen if you stepped forward?  Wouldn't you be going faster than the speed of light?

No, you'd be going so slow in time that your velocity of stepping forward would actually be so small that it could not put you above the speed of light no matter how quickly you tried to move.

Even if you could do what you're talking about, you would only be seeing light, you couldn't actually affect anything.  You could affect the waves, you couldn't affect the source of the waves.  You would see the past, but it would still be the present at the source of the light.
