Bill said, ''The whole 'nothing can travel faster than light' thing is addressing the speed at which stuff can travel /through/ space time. There is no rule against space time expanding or contracting faster than light . . .'' The effect that you are talking about is superluminal recessional velocities, and it applies generally to galaxies that have a redshift greater than z=3. Galaxies with a redshift greater than 3 have redshifts that indicate that they are traveling away from us as greater than light speed, and such redshifts are an indicator of expansion of the universe on a cosmological scale. However, measured superluminal redshifts are observed only beginning at cosmological distances of z=3 or about 6 or 7 Giga light-years from Earth. The distances involved in the CERN experiment are on a terresterial scale, and their experiment does not involve cosmological expansion of the space underneath the experiment as a significant factor. Good question, though. Clear Skies _- Kurt
