Скачать или смотреть Is Dark Energy a lie? Timescape cosmology explained

Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! Is the accelerated expansion of the universe an illusion? Could the mysterious force of dark energy not exist at all? In this video I talk about the mystery of dark energy, Why scientists invented it and the problems it creates. The Hubble Tension, why different measurements of the universe's expansion rate don't agree, and timescape cosmology, which may explain away dark energy. New research finds evidence suggesting the Timescape model might fit the data better than our best cosmological model Lambda CDM!
