Time travel: is it possible?

Is time travel possible? The laws of physics in the microscopic world suggest that it is because the physical processes they define at the subatomic level appear to be either entirely or mostly time symmetric.  In other words the theoretical statements that describe them remain true if the direction of time is reversed.  However, the […]
