Creatable Universes
Joan Josep Ferrando, Ramon Lapiedra, Juan Antonio Morales
TL;DR
This paper explores the criteria for defining energy and momentum in non-asymptotic Minkowskian spaces within general relativity, identifying conditions under which universes could originate from quantum fluctuations.
Contribution
It characterizes the coordinate systems that allow for the identification of creatable universes with zero energy, momentum, and angular momentum.
Findings
Spaces with vanishing energy, momentum, and angular momentum are candidates for creatable universes.
Complete characterization of coordinate systems suitable for defining creatable universes.
Framework for assessing the quantum origin potential of different universe models.
Abstract
We consider the question of properly defining energy and momenta for non asymptotic Minkowskian spaces in general relativity. Only spaces of this type, whose energy, linear 3-momentum, and intrinsic angular momentum vanish, would be candidates for creatable universes, that is, for universes which could have arisen from a vacuum quantum fluctuation. Given a universe, we completely characterize the family of coordinate systems for which one could sensibly say that this universe is a creatable universe.
