General Physics explores the fundamental laws that govern everything from the tiniest subatomic particles to the vastness of the cosmos. This field serves as the bedrock for understanding how the universe operates, covering mechanics, thermodynamics, and electromagnetism without getting bogged down in overly specialized sub-disciplines. It is where the big questions about matter, energy, and force come together to explain the physical world around us.

Below are the latest papers in General Physics, freshly summarized and ready for you to explore.
This study employs Gaussian processes to model-independently reconstruct the dark energy equation of state and potential from Hubble and DESI data, yielding a model-independent Hubble constant estimate of km s Mpc and evaluating the viability of four specific scalar field potentials through chi-square and MCMC analyses.
This paper proposes a geometric quantization approach that extends General Relativity from a four-dimensional Riemannian manifold to an eight-dimensional phase-space framework, deriving a quantized metric tensor without relying on previous approximations to reconcile quantum mechanics with relativistic gravitational fields.
This paper proposes a teleparallel gravity framework utilizing geometric drift vectors to replace the central singularity of black holes with a smooth de Sitter-like core, where gravitational effects arise from torsion rather than curvature, allowing for analytic extensions of trajectories across event horizons.
This paper presents a comprehensive dataset of computed total emissivity values for carbon dioxide, water vapor, and their mixtures across a wide range of temperatures (300–2900 K) and pressure-pathlengths (0.01–50 atm·m), specifically tailored for applications such as oxy-fuel combustion flue gases.
This paper argues for an integrated study of biosignatures and technosignatures by introducing the concept of "substrate-agnostic ecology," a framework grounded in niche construction theory that transcends terrestrial biases to define life and technology through functional agent-ecology couplings rather than specific material substrates.
This paper establishes a necessary compatibility criterion and descent condition for reconstructing static Einstein-scalar systems from independently prescribed metric and scalar profiles, demonstrating that such reconstruction generally fails unless specific constraints are met, as illustrated by the recovery of a known solvable halo and the obstruction of a rational kink ansatz.
This paper contextualizes recent extreme observations of the red supergiant WOH G64 alongside data from other massive stars like Betelgeuse and supernova progenitors to reveal new insights into the complex and surprising lives of these stellar giants.
This paper derives a nonlocal uncertainty relation in an ultraviolet-complete quantum field theory that preserves Lorentz covariance while establishing a minimal localization length and demonstrating that pointlike localization ceases to be a physically realizable observable below the nonlocality scale.
This paper demonstrates that local experimental constraints from Solar System tests, Lunar Laser Ranging, equivalence principle checks, and atomic clocks severely limit the viability of unscreened visible sector couplings in realizing an de Sitter gradient for swampland scalars, thereby restricting the refined de Sitter alternative to specific parameter regions like hilltops or tuned dynamical evolutions.
This paper proposes a geometric quantization framework for the Kerr-Newman black hole spacetime that extends General Relativity to quantum scales, revealing the existence of significant negative Riemann curvatures alongside classical positive ones, which suggests the presence of quantum gravitational sources not accounted for in standard theory.
