Replying to TIME TRAVEL?

do you guys think its possible?

i dont, see i see it as this, in order to go back in time you would have to travel faster than the speed of light (299,792,458 meters per second, for those of you who dont know how fast it is). if you go faster than the speed of light then you wouldnt be able to see any thing since our sight relies on light relfections. also you wouldnt be able to feel n e thing cause you would be moving faster than the speed that the molecules that make up solid objects are moving at.... well thats my shpeil, what do you guys think about time travel?
