Time travel is very achievable within a few years, in my opinion. It just won't be achievable in the sense as we think of it. Imagine a world wherein every molecule has a machine attached (nanotechnology). That machine can save its current state and position. These numbers are saved to a central server (presumably with a large hard drive ), and the molecules react normally. Every nanosecond, the machine saves its position and state. In order to travel back in time, one just tells every molecule to revert to its state and position at a certain time. This information can be retrieved from the central server, and sent to the molecular machines. In essence, this would be going back in time. Of course, many details are left out here, and the time travel would only allow to go as far back as when the "nano-world" was created, but it is an intriguing idea, is it not? Any comments?
