The Third Quantization: To Tunnel or Not to Tunnel?
(MDPI, 2018-03)
Within the framework of the third quantization, we consider the possibility that an initially recollapsing baby universe can enter a stage of near de Sitter inflation by tunnelling through a Euclidean wormhole that connects ...
What if gravity becomes really repulsive in the future?
(Springer, 2018-03-24)
The current acceleration of the Universe is one of themost puzzling issues in theoretical physics nowadays. We are far from giving an answer in this letter to the question of its nature. Yet, with the observations we have ...
Pre-Inflation From The Multiverse: Can It Solve The Quadrupole Problem In The Cosmic Microwave Background?
(Springer, 2018-03-21)
We analyze a quantized toy model of a universe undergoing eternal inflation using a quantum-field-theoretical formulation of the Wheeler-DeWitt equation. This so-called third quantization method leads to the picture that ...
