Erick and I were having an argument earlier over time-travel.  I was arguing that one cannot go back in time prior to the exact moment the time-machine was turned on, but Erick countered that if one could travel about time it would not matter when the time-machine was built because at any moment you would be present inside the time-machine whether in 1988 or 2008.

If testing my time-machine, I would travel first to 1984.  Great year, good music, good movies and fun fashion – plus it’s a safe distance from the present and yet with many modern conveniences.  Following a visit to 1984, I’d pull back to 1884 for a reference and then I’d come back to the 1940s and bounce back and forth down the space-time continuum until I found a prehistoric animal or Atlantis or something that couldn’t be outdone.  

Erick is obviously bored with coming home from work and not working, so he’s now reading about wormhole propulsion and bending space-time:

Special relativity only applies locally. Wormholes allow superluminal (faster-than-light) travel by ensuring that the speed of light is not exceeded locally at any time. While traveling through a wormhole, subluminal (slower-than-light) speeds are used. If two points are connected by a wormhole, the time taken to traverse it would be less than the time it would take a light beam to make the journey if it took a path through the space outside the wormhole. However, a light beam traveling through the wormhole would always beat the traveler. As an analogy, running around to the opposite side of a mountain at maximum speed may take longer than walking through a tunnel crossing it. You can walk slowly while reaching your destination more quickly because the length of your path is shorter.

That said, my mind has wondered to another wormy topic…  Has anyone been reading about these feet washing up on shore in British Columbia?  I blame Ogopogo.  Would you eat sneakers?
