In Dec. 2024, Prof. Alex Filippenko was interviewed by Dr. Brian Greene for the World Science Festival. They discussed the accelerating expansion of the Universe, dark energy, and especially the current "Hubble tension" -- the discrepancy between the measured and predicted current expansion rate. The episode (2 hours long) is now available at https://www.worldsciencefestival.com/programs/mind-the-gap-will-tiny-discrepancies-derail-cosmology/
Alex thinks it went pretty well -- but he asks you to please excuse his error of saying 16 (instead of 14, which is what he meant to say) helium nuclei around t = 45 minutes! (His excuse is that he did the interview after staying up very late for the last Astronomy C10 "bull session," on cosmology.)
The interview already has nearly 100,000 views!
