Can Poincaré recurrences happen eventually in a universe with zero vacuum energy?
I am interested in the topic of possible vacuum up-tunneling and down-tunneling events in cosmology. One popular instance of this is a vacuum decay from a metastable vacuum energy level to a "...

Are vacuum "up-tunneling" phase transition in AdS and Minkowski spaces impossible?
I am interested in the topic of vacuum phase transitions in models of the universe. One popular instance of this is a vacuum decay from a metastable vacuum energy level to a "true" one (in ...

Electrons keeping dynamical quantum fluctuations?
I was thinking about this paper (https://arxiv.org/abs/1405.0298) where the authors argue that there wouldn't be dynamical quantum fluctuations in a De Sitter space as fluctuations would be static ...

Why Superfluid Vacuum Theory has not proved yet that Vacuum space is possible a superfluid?
Our Universe and subatomic world being defects of an omnipresent type of superfluid we call "Vacuum Space" therefore a medium, unknown phase of matter is an intriguing idea expressed by SVT.

Did Stephen Hawking propose that the universe arised from truly nothingness?
Stephen Hawking giving a lecture describing how the universe would have arisen from his model (developed with James Hartle) or "no boundary" conditions, once said:
Unlike the black hole pair ...

Can the vacuum energy be made finite with quantized space
From what I know the reason we have infinite vacuum energy is because according to Quantum Field Theory at every point in space we have something analogous to a harmonic oscillator but since the Zero ...

Are dark energy and zero-point energy the same thing?
According to Quantum Mechanics is it possible that the famous "dark energy" and "zero-point energy" are the same thing that drives the accelerated expansion of the universe or maybe related to each ...
