How to hide a cosmological constant
Abstract
Naive calculations in quantum field theory suggest that vacuum fluctuations should induce an enormous cosmological constant. Furthermore, what if these estimates are right? I argue that even a huge cosmological constant might be hidden in Planck-scale fluctuations of geometry and topology — what Wheeler called “spacetime foam” — while remaining virtually invisible macroscopically.
