Hey Folks,
Had a thought - if you work out the Cosmological constant in SI units it works out to be around [tex]10^{-10} J/m^3 [/tex]. I performed a quick calculation for the Casimir energy (EM modes) for a plate measuring [tex]1 m^2 [/tex] for a plate separation of [tex]1 \mu m [/tex] and found it to be on the order of [tex]- 10^{-9} J [/tex] which works out to be around [tex]- 10^{-3} J/m^3 [/tex].
Note this is NEGATIVE energy, and significantly more negative then the comsological constant is postive.
Would it be wrong (and if so why) to say that the space between the plates is AdS space, eg a space with a negative cosmological const?
