If so, they say you can only travel into the past as the future does not exist. Therefore if this is the case, the 'place in the past' were you travel to. From that palces perspective, the future must exist.

I think i read on here somewhare that Albert Einstien said that time travel was impossible but time seeing was a possibility.

Yes. We are always moving forwards in time every nanosecond.
We all experience our own individual time line but basically the faster you go the slower your personal clock goes.
If you leave your identical twin at an airport and then you fly around the earth in the direction of the earths rotation when you get back to the airport because you have travelled faster than your identical twin you will be several nanoseconds younger and
although this effect is barely noticable it has been proven by the use of accurate atomic clocks.
Therefore if you are several nanoseconds younger than your twin you have travelled into the future by comparison.

apparently a guy named t'hooft (really) said if you make the entire universe the same uniform density then it is possible. how to do this is the clincher.
even if it becomes possible to go back, you actually change all history from your arrival point and the place you left is entirely changed when you arrive back.
all this talk about killing your grandparents is rubbish because in your new revised world your parents would meet and marry other people.
people say ''if only i could go back'' all the time and its crap.
you cant predict the future and thats that. even if you go back in time all events from then on become slightly different so eventually your new world changes completely.

read Brian Greene's the Fabric of the Cosmos
explains modern thinking on time and how even Einstein concluded the arrow of time which we humans think of as our present moving into a future trailing behind a past - is concocted in our heads.
In the real 'out their' everything that will happen has happened from someone's perspective.
He also wrote The Elegant Universe - also a good read.

Well if time travel was possible then in future we would know how to go about it. If this was so then people from our future should have been visiting us today. But they don't because they wont!!!

only the present exists
the past can be inferred by looking at the present and extrapolating the laws of physics backwards
images and impressions of it can also be recorded in things that exist in the present, but the past itself is gone
the future can be forecast by looking at the present and extrapolating the laws of physics forward
we are all moving into the future
nothing can move into the past

Even though I enjoy time travel movies & stories, I doubt it's true because we could seriously mess up the world if we could go backwards or forwards in time.

Yes it is possible! That's why I never win on the lottery, I find the winning numbers but can't get back to place them.

Time travel would have no boundries, if it were possible you could travel into the future, that is why its called time travel, not historical time travel

im sure i read somwhere that they had sent a piece of music back in time by a millionth of a second but would need a powersource the size of 7 suns to do anything bigger
