Re: Speed of light is not constant!

It seems to be an everlasting discussion, how to measure the speed of light. Insisting on metric topology, isn't there a whole sequence of l<sup>p's matching the L<sup>p's, the difference being that the former is based on integers, the latter on real numbers? Insisting on literalcy, "speed of light"...

Re: Spaceship speed limits

The illusion part of the fast forward force field sems to be settled, the teleportation's jump being related to the distance between the bow and the stern of the teleportee.

Re: Spaceship speed limits

Still, although the velocity of light has not been exceeded, the space ships still seem to be moving along faster that c/2, namely 19/22 nds of c; probably explicable by the bulk of the stargate mechanism. Although a single jump is plausibly an illusion, the criterion of "how long does it take for t...

Re: Spaceship speed limits

So, space ships have their speed limits, but extended structures can behave differently, especially with respect to superluminal movement. What if the structure is not extended? A recent example was the reasonable explanation in the LifeWiki that the stargate was an optical illusion, but that leads ...
