Takehome point: “Everyone would be keen to abandon the theory if there’s a better alternative, nobody’s married to the Big Bang theory”

Scientific American told readers recently that the James Webb Space Telescope is “breaking the Big Bang paradigm” so we can be fairly sure that astrophysicists have a lot of questions. The October 1 debate at the HowTheLightGetsIn festival in London represented a variety of views: There are those, like Sabine Hossenfelder, who think that physics will probably never be able to tell us how the universe came about and argue that we should think of the Big Bang theory as little more than another creation myth. And then there is Eric Lerner. The author of a recent article “The Big Bang Didn’t Happen” that went viral, Lerner articulated a challenge to the current scientific consensus in cosmology that caused quite Read More ›
