Both options would probably accelerate pretty slowly, and not get up to relativistic speeds until they were "out of range" of the earth laser/sun. | |

| Jul 5, 2011 at 19:05 | comment | added | Alan Rominger | @lurscher My intent is that a negative answer to this question results in a sci-fi conclusion of "guess we're stuck with suspended animation". It's certainly debatable as to whether or not time travel to the future is of utility in the first place. Also, since I'm allowing a "large" stationary reference frame, propellent-less travel is already possible, consider the case of protons in the LHC. Only problem is that the required energy is >>mc^2 still. | |
