The laws of physics say we can't accelerate through the speed of light, but it doesn't say we can't travel faster than light, nor does it say time travel is impossible. Particles traveling faster than light can travel back in time. Communicating with those particles has proven to be difficult. Also, traveling faster than light is pretty difficult. But, the main law is that you can't accelerate through the speed of light. Another possibility is compressing space so that you're not traveling faster than light, but you're covering more space. It's probably more likely that we could colonize Mars before we will have a vessel capable of compressing space and traveling through it in an efficient manner. https://en.wikipedia.org/wiki/Alcubierre_drive https://en.wikipedia.org/wiki/Alcubierre_drive
