I thought that this effect was measured as an energy level which showed that there is a little more matter than anti matter which is the contributor of the force. If there is more matter than anti matter, how could a zero energy force universe appear or emerge out of nothing?
The sum difference of the greater number of photoic energy verses the fermionic photinos energy is supposed to be so great over the entire universe that there is discussion as to why this energy doesn't "cause space-time to curl up".
I've read a few other web sites trying to explain this but it is above my ability to comprehend just what they are talking about. I'm not sure if they are refuting the Casimir effect or just explaining it away as a quantom anomole.
Unless I am not grasping the Casimir effect correctly, the evidence of this force would not allow a zero energy force universe to exist.
