Theoretical Physicist Challenges Dark Energy Theory with New Supernova Data
Theoretical physicist Subir Sarkar from the University of Oxford is challenging the widely accepted theory that the universe is accelerating in its expansion due to dark energy. Sarkar, along with researchers Animesh Sah and Mohamed Rameez, has re-evaluated data from Type Ia supernovae, which have traditionally been used to support the existence of dark energy. By applying a correction for the age of the progenitor stars, the team found that supernovae from younger progenitors appear fainter than those from older ones. This faintness, they argue, creates an illusion of acceleration. Their findings suggest that the universe's expansion may not be isotropic, as previously thought, but rather anisotropic, meaning it does not accelerate uniformly in all directions.
