The peculiar properties of the false vacuum stem from its pressure, which is large and negative.
According to general relativity, however, there is a gravitational effect that is very important under these circumstances. Pressures, like energy densities, create gravitational fields, and in particular a positive pressure creates an attractive gravitational field. The negative pressure of the false vacuum, therefore, creates a repulsive gravitational field, which is the driving force behind inflation.
De breed geaccepteerde verklaring id die van kwantum vacuüm fluctuaties van het elektromagnetische veld (virtuele fotonen).Het experiment met de twee zich dicht bij elkaar bevindende platen (Casimir) is een bewijs dat deze vorm van negatieve massa weldegelijk bestaat.
