Time travel has not been shown to be impossible. Einstein showed time was a dimension, just like forward-backward, left-right or up-down. We affect all 4 by moving through them. This is realised by the famous lorentz contractions, time slows as one travels faster and objects appear shorter. Sadly this is relative to the speed of light, standing at 300,000km/s so we simply do not notice this effect but it is very well proven at fermilab and CERN. This effect is linked to Einstein's relation E=mc^2 which underlies nuclear power, an obvious proof of his work. Further Einstein showed if one travelled at the speed of light, time actually stops, as I mentioned earlier it slows the faster one travels, if one could travel faster than light you would indeed travel back in time. Sadly this is not possible due to mass increasing with velocity, and reaching infinite value at the speed of light. However, general relativity views gravity as a warp in space time, thus a large mass, like the sun, warps this fabric significantly, distorting the relation between time and space. It was later shown by a mathematician that in a spherical universe one could travel to any time or location simply by traversing the correct trajectory. We do not live in such a spherical universe, the shape of our universe is unknown, and so time travel remains a possibility. Physicists are unsure of the feasbility of time travel, we may simply not have the technology yet.
