The Third Quantization: To Tunnel or Not to Tunnel?

Galaxies, 2018
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 the recollapsing and ...

A Low‐Order Data‐Driven Model of ENSO Diversity

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Linear Inverse Models (LIMs) are widely used data‐driven tools for studying El Niño Southern Oscillation (ENSO). However, standard LIMs struggle to simulate the observed asymmetry and diversity of ENSO events. Observations reveal that strong Central Pacific (CP) La Niñas and extreme Eastern Pacific (EP) El Niños occur more frequently than ...

Multiverse Predictions for Habitability: Number of Potentially Habitable Planets

Universe, 2019
How good is our universe at making habitable planets? The answer to this depends on which factors are important for life: Does a planet need to be Earth mass? Does it need to be inside the temperate zone? are systems with hot Jupiters habitable? Here, we

Multiverse—Too Much or Not Enough?

Universe, 2019
The aim of this essay is to look at the idea of the multiverse—not so much from the standpoint of physics or cosmology, but rather from a philosophical perspective. The modern story of the multiverse began with Leibniz.

Do We Live in the Best of All Possible Worlds? The Fine-Tuning of the Constants of Nature

Universe, 2017
Our existence depends on a variety of constants which appear to be extremely fine-tuned to allow for the existence of life as we know it. These include the number of spatial dimensions, the strengths of the forces, the masses of the particles, the ...

Multiverse Predictions for Habitability: The Number of Stars and Their Properties

Universe, 2019
In a multiverse setting, we expect to be situated in a universe that is exceptionally good at producing life. Though the conditions for what life needs to arise and thrive are currently unknown, many will be tested in the coming decades.

Multiversal entropy and information conservation in black hole nucleated baby universes

Nuclear Physics B
We propose a novel mechanism by which supercritical black holes formed via vacuum bubble or domain wall nucleation during the inflationary epoch not only give rise to baby universes, but also contribute to a generalized entropy accounting in the ...
