Quantum Field Theory of Black Hole Perturbations with Backreaction: I General Framework

Universe
In a seminal work, Hawking showed that natural states for free quantum matter fields on classical spacetimes that solve the spherically symmetric vacuum Einstein equations are KMS states of non-vanishing temperature.

Quantum Effects on Cosmic Scales as an Alternative to Dark Matter and Dark Energy

Universe
The spin-torsion theory is a gauge theory approach to gravity that expands upon Einstein’s general relativity (GR) by incorporating the spin of microparticles. In this study, we further develop the spin-torsion theory to examine spherically symmetric and

Nisti-Hasti Framework — Unifying General Relativity, Quantum Mechanics, and Cosmology

The Nisti-Hasti framework introduces two fundamental components—Nisti (dynamic quantum vacuum fluctuations) and Hasti (conversion of matter into spacetime geometry)—to unify four major problems in modern physics (dark energy, dark matter, the black hole information paradox, and quantum gravity) into a single mathematical structure.

Batalin–Fradkin–Vilkovisky quantization of Einstein gravity with off-diagonal solutions encoding Hořava type generating functions

European Physical Journal C: Particles and Fields
We develop and apply the Batalin–Fradkin–Vilkovisky (BFV) formalism for the covariant quantization of generic off-diagonal solutions of the Einstein equations in general relativity (GR).

The Black Hole Unification: Bridging Quantum Gravity, General Relativity, and the Cosmological Constant

A groundbreaking non-local gravity theory where black holes are the dynamic mediators of cosmic mysteries. 'The Black Hole Unification' presents a novel framework where 4D spacetime is an 'open system' interacting with an 'exo-spacetime field.' This approach offers a unique path to reconcile General Relativity and Quantum Mechanics by directly linking ...

Det kosmologiska valet. Om Gud, big bang och universums existentiella mysterium

Svensk Teologisk Kvartalskrift, 2013
One of the premises of the so-called Kalām Cosmological Argument is that the universe began to exist. Modem Big Bang cosmology may seem to provide remarkable support for this hypothesis, since it estimates the universe to be 13.7 billion years old.

Grid Refresh Cosmology: A Discrete Spacetime Framework for Unifying Quantum Mechanics and General Relativity

宇宙格點刷新論(Grid Refresh Cosmology,GRC)是一套以計算系統為類比工具的宇宙學詮釋框架,從兩個底層常數出發,GL(格點長度)與 GR(刷新基準容量),為量子力學與廣義相對論提供統一的底層詮釋語言,並對暗物質、暗能量、希格斯機制、引力波與宇宙學常數問題提出內部一致的推論性解釋。框架將時空建模為離散泡泡狀網格,透過網格不可分割性推導洛倫茲因子與光速不變性,並將每個網格泡泡的基礎資訊量對應為希格斯場的底層機制。概念由 Hyatt Pan 推導,2026 年 3 月。

Temporal‑Lattice Quantum Gravity: A Discrete Spacetime Framework for General Relativity, the Standard Model, and Cosmology

This preprint proposes a temporal‑lattice framework for quantum gravity and unification. The central hypothesis is that spacetime at the most fundamental scale is a causal lattice with discrete time steps and spatial sites, and that all physical degrees of freedom—geometry, gauge fields, and matter—are realized as temporal‑phase patterns on this ...
