Corrected Pantheon+ analysis of supernovae challenges accelerating universe claim

Research from the Tata Institute of Fundamental Research in Mumbai and Professor Subir Sarkar from the University of Oxford challenges the commonly accepted view that the universe’s expansion rate is accelerating due to “dark energy” from the quantum vacuum. This letter has been published in the Monthly Notices of the Royal Astronomical Society.

Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating and that this is driven by “dark energy” arising from the quantum vacuum. Their letter has been published in Monthly Notices of the Royal Astronomical Society.
