Consider this. If you were on a planet 1000 light years away from earth and was looking at the earth through a telescope you would be seeing what was happening here 1000 years ago. Now, what if you were on earth and had a spaceship that could travel faster than the speed of light and went out to that planet that was 1000 light years away, turned around and came back to earth would you go back in time? Probably not, but its interesting to think about.

If you could travel from our planet to that planet 1000 light years away in a second then what would happen? think people!
Do you think it will ever be possible to go that fast or to accomplish something like that we would need teleportation?

In its most simplest form - going forward in time simply requires you to move "faster than time". For instance, when you jump aboard a high velocity vehicle (such as a jet) you're moving faster than time, so when you get off the jet you have aged less than those on the ground (although only by a .0000000001 of a second) -- this has been proved through experiments using an atomic clock.
There are also other methods -- involving gravity, mass, etc. - but I cannot be bothered to explain it right now.
Keep talking dude. faaaaaaaaaaaaaaaaar out

Basic physics would intervene. Mass increases at very high speeds. That means that the gravity of an object increases also. I believe it is impossible for an object with mass to be pushed to the speed of light because it would become dense enough to collapse into a singularity.

You got it the wrong way round. Time runs slower relative to a stationary object as speed increases. The experiment you referred was probably the one where an atomic clock was mounted inside an SR - 71 Blackbird.
Satellites that use atomic clocks have to be calibrated because they run slightly slower than those on earth. Orbital velocity and their distance from the earths gravitational field both effect it in the same way.

Nows my chance to try to sound smart.
I think traveling faster than the speed of light is possible.
By using the power of 'gravity' yes gravity.
'Black holes' are known to have an extraordinary amount of gravity, so much that it actually pulls in light through it. So that means gravity is stronger and faster by being able to catch light and pull it in.
Also scientists and experts believe 'UFO's' use gravity to power their ships, what else can explain the split second change of direction at fantastic speeds that would otherwise crush the occupants and the ship into microscopic bits. By gravity to move and counter-react that kind of force.
Saying that how are they able to come to earth so many times at short intervals when they probably live hundreds of thousands of light years away? If they traveled the speed of light at that distance it would take hundreds of thousands of years to get here. UFO's must be going extraordinaryingly faster than the speed of light.

Theoretically it IS possible. Considering time is linear... the only reason our little minds break it down is so our mind can digest it, but time is actually one straight line that goes forward and backwards at the same time. It's definitely possible.
this is applied to particles already. in huge accelerator tunnels, a particle with lets say only 1ms of a lifespan is brought to close to the lightspeed (it is impossible to reach it), and for example for the outside observer, its life expands to 1 minute.. so the particle went forward 1 minute in time within 1ms only.. thats an example of time travel.
nothing can go faster than lightspeed.. but teleportation is theoretically possible.. they even teleported a photon in an experiment.. but this doesnt have to do with time travel i believe.. you can just take a "shortcut" and get to a place quicker than a lightbeem, but it doesnt mean you have traveled faster than lightspeed or did a time travel, its a different concept.
