Quantum gravity represents the frontier where the very large meets the very small, attempting to unify Einstein's theory of gravity with the strange rules of quantum mechanics. This field explores the fundamental fabric of spacetime, seeking to understand how the universe behaves at its most extreme scales, from the heart of black holes to the moment of the Big Bang. Because these concepts often involve complex mathematics, they can feel distant to non-specialists, yet they hold the key to a complete picture of physical reality.
At Gist.Science, we bridge this gap by processing every new preprint in this category directly from arXiv.

Below are the latest papers in quantum gravity, offering fresh insights into the nature of our cosmos.
This paper demonstrates that a frontier Large Language Model (Claude) interfaced with a computer algebra system (Maple) and enhanced with in-context learning via worked examples can reliably execute complex algorithmic computations in theoretical physics, specifically for cosmological perturbations in modified gravity theories, while also identifying current limitations and improvement strategies.
This paper proposes a non-parametric equation of state that reveals non-conformal behavior beyond neutron star densities, characterized by an early stiffening followed by extended softening to satisfy observational and theoretical constraints, thereby providing evidence for a hadron-quark phase transition in the cores of massive neutron stars.
This paper reviews the principles, methodologies, and future prospects of using gravitational-wave standard sirens from both bright and dark sources to independently measure cosmological parameters, particularly the Hubble constant and dark energy, with current and next-generation detectors.
This paper computes the gravitational waveform for a radially infalling particle into a Schwarzschild black hole, achieving the highest accuracy level in the literature (3.5PN order) by incorporating both conservative and radiation-reaction effects within the post-Newtonian approximation.
This paper introduces a unified HeunC framework that reformulates the Teukolsky equations to compute gravitational-wave fluxes from generic Kerr orbits with high precision and efficiency, achieving relative errors of while reducing computational costs by factors of 2–10 compared to existing state-of-the-art methods.
This paper investigates static spherically and axially symmetric self-gravitating non-Abelian monopoles within modified gravity, demonstrating that the gravitational modifications introduce significant differences compared to Einstein-Yang-Mills-Higgs theory, particularly for systems with strong Higgs self-coupling.
This paper derives general multimessenger consistency conditions within the Friedmann cosmological model that allow for probing the Universe's curvature and testing the cosmological constant using gravitational and electromagnetic wave luminosity distances, independent of the dark energy equation of state and specific density parameters.
This paper investigates the divergent perturbative series of correlation functions for a massless, self-interacting scalar field in de Sitter space by applying autonomous equations to both the original series and their Borel-Le Roy transforms, demonstrating that the latter approach yields results that substantially better match the stochastic picture while also offering new derivations and methods for extracting perturbative coefficients.
This paper reviews dusty plasma physics and cosmic wave interactions while deriving a modified Jeans instability criterion for an expanding, radiation-pressure-dominated universe using the Einstein-de Sitter model to explain the formation of cosmological structures.
Using an updated JWST-based gravitational lens model, the paper confirms that the Bullet Cluster exhibits a residual missing mass discrepancy under Modified Newtonian Dynamics (MOND) that is centered on its collisionless galaxies, similar to other clusters of comparable mass.
