Subir Sarkar

Subir Sarkar, theoretical physicist and former head of Oxford's particle theory group, argues that dark energy may be a local illusion. He discusses directional cosmic acceleration, reanalysis of supernova and radio/quasar dipole data, challenges to isotropy and the cosmological-constant assumption, and alternative inhomogeneous models that could mimic acceleration.

In a captivating discussion, John Dupré, a philosopher famed for his insights into the philosophy of science, teams up with astrophysicist Subir Sarkar and philosopher Nancy Cartwright. They explore how contemporary physics challenges traditional notions of physicality, proposing energy and fields as new foundations of reality. The conversation segues into the fluidity of existence, emphasizing action and processes over static materialism. Additionally, they tackle emergent phenomena in biology and physics, delving into how context shapes causality and stability.
