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.

At Gist.Science, we process every new preprint in this General Physics category as it arrives from arXiv, ensuring you never miss a breakthrough. For each paper, we provide both a detailed technical summary for experts and a plain-language explanation that makes complex ideas accessible to everyone. Below are the latest papers in General Physics, freshly summarized and ready for you to explore.

Evolution of Size, Mass, and Density of Galaxies Since Cosmic Dawn

This paper argues that the apparent discrepancies between early-universe galaxy properties and standard Λ\LambdaCDM predictions are resolved by the CCC+TL cosmology, which posits covarying coupling constants and a tired light effect to explain observed redshifts, thereby reconciling galaxy size, mass, and density evolution with observational data without requiring unrealistic formation rates.

Dynamical dark energy in the Bianchi Type-V Universe with DESI DR2 BAO, SNIa compilation and RSD measurements

This paper investigates dynamical dark energy models within an anisotropic Bianchi Type-V universe using a 1+31+3 covariant thermodynamics approach and confronts them with the latest DESI DR2, SNIa, and RSD datasets, finding that the combined anisotropy and dynamical dark energy framework effectively accommodates late-time observations and mitigates the H0H_0 and S8S_8 tensions, despite Bayesian criteria still favoring the standard Λ\LambdaCDM model.

Damour-Solodukhin Wormhole as a Black Hole Mimicker: The Role of Observers' Location

This paper proposes that the observed identity of a Damour-Solodukhin wormhole as either a black hole or a wormhole depends on the observer's location, utilizing Tangherlini's concept of gravitational indeterminacy to show that Fresnel reflection and transmission coefficients for probing photons are determined solely by the wormhole's free parameter λ\lambda rather than its mass.

Reconstruction of a dark energy model for the Dirac-Born-Infeld scalar field with the Hubble and DESI data via Gaussian process

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 69.53±2.6869.53 \pm 2.68 km s1^{-1} Mpc1^{-1} and evaluating the viability of four specific scalar field potentials through chi-square and MCMC analyses.

The Derivation of Phase-Space Metric in a Geometric Quantization Approach: General Relativity with Quantized Phase-Space Metric and Relative Spacetime

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.
