Dark Energy

Researchers have proposed an alternative to dark energy for the universe's accelerating expansion. Using an extended form of Einstein's general relativity called Finsler gravity, they show that cosmic speedup can emerge naturally from spacetime geometry. This approach, detailed in a recent study, challenges the standard cosmological model.

New supercomputer simulations suggest that dark energy, the force accelerating the universe's expansion, might be dynamic rather than constant. Led by researchers in Japan, the study aligns with observations from the Dark Energy Spectroscopic Instrument (DESI). This could reshape understanding of cosmic structure formation.
