Sticky Dark Energy: Friction in the Cosmic Fluid Could Explain the Universe’s Speed-Up
A new Bayesian analysis combining DESI DR2, supernova, and Planck data shows that bulk viscosity in a dark energy fluid ...
One Field to Rule the Dark Sector: New Gravity Model Takes Aim at the Hubble Tension
A new scalar-vector-tensor theory of gravity unifies dark energy and dark matter while offering a mathematically consistent route to easing ...
Torsion Cannot Explain Dark Energy: New No-Go Result Rules Out Einstein–Cartan Rescue
A new no-go theorem shows that the adiabatic torsion mode of Einstein–Cartan cosmology cannot rescue the Hubble-cutoff model of holographic ...
Geometric Flow Turns a Black Hole Into a Traversable Wormhole on Paper
A new theoretical study shows that an almost eta-Ricci–Yamabe geometric flow, coupled to an imperfect fluid in a dark-energy regime, ...
Dark Energy Cools Black Holes: Exact Quantum Solution Reveals Quieter Hawking Radiation
A new exact solution of the Klein–Gordon equation in a Kiselev black hole spacetime shows that dark energy suppresses Hawking ...
Mock Universe Stress Test Finds Dark Energy Hints May Be Statistical Illusions
A new mock-ensemble analysis shows that single-probe cosmological datasets generated from a perfect cosmological-constant universe can still produce posterior shifts ...
Phantom Fields Tame the Chaos of the Universe’s Final Moments
Theorists have explained why a universe filled with exotic phantom energy oscillates in volume instead of crashing into a singularity, ...
