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.
Using the Euclidon method, this paper presents a new axially symmetric stationary solution to Einstein's vacuum equations that describes N rotating masses and generalizes to N arbitrary static axially symmetric masses or N Kerr-NUT solutions under specific limiting conditions.
This paper proposes a logarithmic dark energy model (CDM) constrained by recent cosmological datasets, which yields a higher Hubble constant () that partially alleviates the Hubble tension while remaining statistically competitive with the standard CDM model.
This paper proposes that applying a Lorentz-invariant mixed metric tensor equation to a free neutrino, which treats spacetime variables as equivalent and interchangeable, reveals an internal change in the particle when viewed through conflicting perspectives, a conclusion that holds only if those perspectives are mutually compatible.
This paper argues that the computational speedup of quantum algorithms stems from their teleological nature as goal-directed evolutions, a physical principle that, under specific cosmological assumptions, also explains the teleological character of biological evolution.
This paper proposes an extended equivalence principle for matter-free gravitational sources to demonstrate that a degenerate Klinkhamer wormhole behaves like a test particle in a Schwarzschild field, inevitably collapsing from a long-lived traversable state into a nontraversable Einstein-Rosen wormhole.
This paper proposes that a predicted fourth generation of fermions, characterized by unique electric charges and conserved quantum numbers that prevent interaction with known matter, forms neutral composites that serve as candidates for both super-massive galactic core dark matter and galactic halo dark matter.
This paper demonstrates that gauge symmetry constraints in a covariant Effective Field Theory framework impose a specific algebraic relation between parameters in the Levy-Helayel-Neto model of Loop Quantum Gravity, thereby revealing that the apparent freedom in defining the Hamiltonian is illusory and that kinetic and cubic interaction terms are fundamentally equivalent on-shell.
Using the Pantheon+ Type Ia supernova catalog, this study demonstrates that the universe model is strongly favored over the standard CDM model because it satisfies general relativistic energy conditions while CDM violates the strong energy condition, resulting in an approximately 89.5% likelihood for the former.
This paper explores the hypothesis that the Casimir effect, mediated by the time-energy uncertainty relation at sub-Fermi length scales, plays a fundamental role in generating electron-positron and quark-gluon plasmas, resulting in a derived temperature-distance relation with potential observable consequences.
This paper proposes that an electron can be described as a point moving at the speed of light whose trajectory satisfies fourth-order differential equations, where the relative motion between its charge center and mass center generates spin and magnetic properties, necessitates radiation in electromagnetic interactions, and implies that the fine structure constant is the sole relevant parameter for electron-electron interaction while calling for a revision of General Relativity.
