UC Davis Study Questions Need for Dark Energy in Cosmic Expansion
0
·8 viewsResearchers at UC Davis have proposed that dark energy may not be required to account for the accelerating expansion of the universe. Their analysis identified weaknesses in the widely used Lambda-cold dark matter model, drawing on Einstein's equations. By studying instabilities within Friedmann spacetimes, the team suggests alternative explanations for how the cosmos expands. The work also raises questions about the Copernican principle as it applies to current cosmological models. If validated, the research could substantially change scientists' understanding of cosmology.
