New Black Hole Model Keeps Curvature Below the Planck Scale Everywhere
Theorists have built a regular black hole model with a flat core and a degenerate inner horizon in which the...
Two atoms, three spacetimes: when cosmic expansion, acceleration and heat tell the same story
A new theoretical study shows that a single atom cannot distinguish de Sitter expansion, uniform acceleration, and a thermal bath...
Probing the sensitivity of dark energy dynamics to equation of state parametrization flexibility
A theoretical analysis finds that the apparent preference for evolving dark energy over a cosmological constant is modest and depends...
Why Quarks Look Free Above the Chiral Crossover Even When Confinement Persists
A new theoretical analysis shows that conserved charge fluctuations mimic free quarks above the chiral crossover because they are insensitive...
Cosmic frame-dragging may explain MOND’s mysterious acceleration constant
A new theoretical study proposes that MOND's universal acceleration constant could arise from linear frame-dragging by the expanding universe within...
Einstein–Cartan pseudoscalaron inflation, reheating and nonthermal leptogenesis
A theoretical study shows that an Einstein–Cartan inflation model with a torsion-born pseudoscalar inflaton necessarily produces the observed baryon asymmetry...
JWST catches galaxies in the act of quenching with powerful neutral winds
JWST observations of blueshifted sodium absorption reveal that powerful, largely AGN-driven neutral outflows accompany rapid star-formation quenching in massive galaxies...
Physicists Map Every Possible Fate of the Universe in Lovelock Gravity
A complete qualitative analysis of Lovelock gravity reveals exotic cosmological scenarios, including a 'Big Shock' beginning that replaces the Big...
Research report: On compositeness of and its decay to
A new theoretical analysis finds the exotic charm-strange meson Ds0*(2317) is a nearly equal mixture of a compact cs̄ core...
Hybrid Decision Model Ranks Airspace Complexity for Drone Fire Patrols
A hybrid multi-criteria decision framework combining fuzzy AHP, entropy weighting and grey-relational TOPSIS ranked seven grid regions of low-altitude airspace...
