Vacuum Energy and Child Universes

Eduardo Guendelman

A universe created in the laboratory from a bubble of false vacuum.

In particle physics, spontaneous breaking of scale invariance is applied to confinement mechanisms of quarks and gluons, while in gravity and cosmology it relates to the present universe acceleration, quintessence scenarios and early universe inflation. In gravity and cosmology, it is implemented in the context of the Two Measures Theory, which I developed with Alex Kaganovich, addressing the above cosmological questions and providing an interesting solution to the 5th force problem. I also study the possibility of creating a universe in the laboratory starting from a bubble of false vacuum.
