This thread is kinda old, but I think time travel will be possible. Most likely not in our lifetime but definitly possible. Some day scientists will find a powerful enough power source to propel a space ship faster than the speed of light. Just like if Ikeep modding my Civic it will be faster than a Vette. 
Another problem is the frrail human body, if you watch Ghost in the Shell in the future we will probably have cyberbrain and artificial body, those things can be made to withstand the force of traveling at light speed.
I believe time travel is possible, but we won't see it in our lifetime.
did you read my post to travel AT the speed of light you would need an infinte amount of force, if you have ever studied relativity and physics in depth you would know that the physics are purely impossible
the part about wormholes, well that isn't really perceptual time travel, that is similar to (not the same because of the wormhole thing) me saying it takes an hour to walk somewhere and then driving there instead and saying that perceptual time travel has occured, it is a good idea but it does not work
