Resum
In this paper the consequences of quantum gravitational effects in cosmological voids are studied through the use of the well-known and reliably calculable long-range quantum corrections to the gravitational potential. The line-element corresponding to these quantum-modified voids in a Universe possessing a cosmological constant is obtained. It is shown that the quantum vacuum in the voids is interpretable, through Einstein's equations, as a highly rarefied effective anisotropic fluid permeating...
