Overview
- Researchers from ZARM at the University of Bremen and the Transylvanian University of Brașov published the work in the Journal of Cosmology and Astroparticle Physics.
- Recasting the Friedmann equations within Finsler gravity yields an accelerating universe even in vacuum without inserting a dark energy term.
- The framework extends spacetime geometry to a direction-dependent form that can better account for the behavior of matter such as kinetic gases.
- The team emphasizes that the study does not rule out dark energy but offers a geometric mechanism that could explain part or all of the observed acceleration.
- Validation will require comparing the model’s predictions with Type Ia supernova distances, CMB anisotropies, gravitational lensing, and large-scale structure surveys, with implications for possible revisions to ΛCDM.
