Cosmology: The Good, Bad, & Ugly - Dr. C.S. Unnikrishnan, DemystiCon '25, DemystifySci #382
Dr. C.S. Unnikrishnan, a physics professor at the TATA Institute, critically examines the standard ΛCDM cosmological model. He discusses the robustness of observational facts like redshift and CMBR while highlighting challenges in validating cosmological theories. Unnikrishnan also critiques the assumptions of dark matter and dark energy, explores alternative models, and questions claims about cosmic expansion impacting only certain systems. He argues for a shift toward data-based refutation, suggesting that current models may need significant revision.

Was Einstein Wrong to Ignore Ernst Mach? - Dr. C.S. Unnikrishnan, #253
Dr. C.S. Unnikrishnan, a professor at the School of Quantum Technology, challenges traditional physics assumptions with his Machian approach. Topics include reevaluating Einstein, testing the speed of light, issues with simultaneity, Michaelson's aether detection, Bergson's criticism of relativity, and evidence of light speed changes.
