Dark Energy from Entanglements with Mirror Universe

Merab Gogberashvili, Tinatin Tsiskaridze

We investigate a possible resolution of the dark energy problem within a pair-universe framework, in which the Universe emerges as an entangled pair of time-reversed sectors. In th…

Hubble Tension as an Effect of Horizon Entanglement Nonequilibrium

Alexander S. Sakharov, Rostislav Konoplich, Merab Gogberashvili +1

We propose an infrared mechanism for alleviating the Hubble constant tension, based on a small departure from entanglement equilibrium at the cosmological apparent horizon. If the…

The width of a black hole atmosphere

Merab Gogberashvili, Tinatin Tsiskaridze

Black holes, as classical solutions of General Relativity, are expected to exhibit quantum properties near their horizons. In this paper, we examine the behavior of quantum particl…

Ultra High Energy Neutrino Event KM3-230213A as a Signal of Electroweak Vacuum Turbulence in Merging Black Hole Binaries

Alexander S. Sakharov, Rostislav Konoplich, Merab Gogberashvili

The recent detection of the ultra-high-energy neutrino event KM3-230213A (220 PeV) by KM3NeT telescope poses a challenge to conventional astrophysical models, particularly in…

The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics

Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533

The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…

Black Holes and Baryon Number Violation: Unveiling the Origins of Early Galaxies and the Low-Mass Gap

Merab Gogberashvili, Alexander S. Sakharov

We propose that modifications to the Higgs potential within a narrow atmospheric layer near the event horizon of an astrophysical black hole could significantly enhance the rate of…
