I get the space-time vector thing. You said that, when moving at the speed of light, one moves through time at a velocity of zero, thus giving the appearance of infinitely fast movement. So if one was able to achieve zero movement (which would probably require achieving zero energy?), wouldn't time also appear to be moving infinitely fast (even though it was actually moving at the speed of light).
- lisper 13y ago> when moving at the speed of light, one moves through time at a velocity of zero When moving through space at the speed of light one moves through time at speed zero. Likewise, when moving through space at speed zero one moves through time at the speed of light, which is one second per second. This is the normal state of affairs that you experience day to day. It is not possible to achieve zero movement through spacetime. In this universe, everything is always moving through spacetime at the speed of light. The only thing that changes is the direction of motion: more through space, less through time, and vice versa.
