ok, first off to all the people who try to say, time travel = impossible because no tourists from the future. What if they don't want us to know they are there? Or perhaps it is illegal except for goverment purposes. What if they are using some sort of cloaking feild? Even now we are developing equipment that can render someone 75% 'invisible' by using nano technology and camera/video equipment on a coat. The japanese were the first to do it.
As for time travel, depends on how you look at it. You, right now, can walk into your bathroom and see into the past. I said see, not travel so keep that in mind.
Go stand about 10 feet from your bathroom mirror and look at yourself. If light travels, i beleive, 1 foot every nanosecond, then you are observing the light bouncing off of you aprox 10 nanoseconds ago. Yes, seeing into the past is possible, just think about watching a star 300 million light years away. You are not seeing how the star looks now, but 300 million light years into the past.
The problem with this is noone likes to accept it because we have not found out a way to specifically choose when and where in time we want to see. Unfortunatly, many science fiction movies about the subject of seeing, and traveling to the past has given many people a false image of what it will be like.

I do not think time travel is possible in the sense we would like to believe. At the best we could travel at nearly the speed of light. This would be very expensive and we may not get anywhere at the end of it. A simple answer would be to just change the dimension. This is probably what the mythological figures did as they suddenly appeared and disappeared at will.

Information cannot be sent faster than the speed of light. Quantum Mechanics confirms this. You may be referring to time dilation, the effect that a clock will run slower aboard a spacecraft traveling near the speed of light, thus while the astronaut may only age a year on his voyage, Earth will have aged much longer. This effect is very real and confirmed experimentally. Is this 'time travel'? Sort of "planet of the apes"ish but strictly speaking you are only slowing down time on the spacecraft.

The beautiful thing about time "the illusion", is its uncanny way to create different "realities" of itself. Once can easily travel through time (when given the right credentials) without changing the fututre or the past. Well, this is just a theory.

The prof that people can't travel to the past, is that we haven't been invaded by turists of the future. Also, we are constantly travelling into the future, in case you haven't noticed.

we are always traveling into the future never the past

see this logical analysis ,isnt it apparent that since we havent got any visitors from the future till now which means that time travel to the past is not possible and has not been achived by anyone in future too.....

Your traveling in time now. So yes, time travel is possible.

we are traveling in the future every second. time travel was possible if relativity was correct. but now many are trying to prove it wrong.

If it is possible it's going to be very dangerous. Most people would go back a few minutes for the first test and then we'll get caught in a loop. Very bad news. I hope it's never possible.
