I was reading in another thread about a higgs-boson condensate, where it was stated that the speed of light has been reduced to around 40m/h (or something like that).

This brings up 2 questions on my behalf, which im hoping to clarify, atleas somewhat.

Isnt the speed of light constant? Im pretty sure that einstein claimed (without being disproven) that light travels at the maximum speed possible within a certain space, or length. As the pohotons propogate themselves as fast as, well, universally possible.

the article about higgs-boson condesates also said something about a null-energy field, or something, indicating that the is mass constantly existing, even within a vacuum, at 0k.

is this correct? if so

Is there a chance that, after observing the relative low speed of light in higgs-boson condensates (HBC)that not only does the speed of light (maximum velocity of mass) vary, but that this can be a function, atleast to a degree defined by the temperature of space? (not stricly outside of earth, but generally).

Also, could this assumption make possible, and i know this is a stretch, that interspellar space is smaller than imagined, and that by measuring relative distances by the speed of light, in fact produces faulty numbers?

say a box with the dimensions 1m(squared) is filled with a HBC, light would take alot longer to travel thru, than it would say on a stretch of highway, and that calculating the size of this given box with the light speed calculations, would give a false answer? as we know for a fact that the box isnt more than 1meters long each side?

so to conclude;

1; given HBC's, is the speed of light constant? (from a relative viewpoint, where we know how far a distance is, using another measurement than lightspeed)

2; may objects in the hubble mirror, in fact be closer than they seem?

hope to get some informed answers, short time lurker, first time poster. [
