Two things many cosmologists would like to get rid of are the Big Bang and apparent fine-tuning of the universe. Telling a different story is difficult mainly due to lack of evidence for a different story but they can make do with discrepancies. But then maybe the years have made some of us cynical.
he author of Lost in Math: How Beauty Leads Physics Astray, makes clear that cosmic inflation was intended to deal with evidence for fine-tuning, which she considers a “waste of time.” But, as she shows, the cosmology has gone nowhere.
Error alone does not apparently explain the discrepancy in these figures: For some methods, which rely on using the light from supernova and pulsing stars called Cepheid variables to determine their changing distance, it appears that objects move away from the Earth 73 kilometers per second faster for every 3.26 million additional light-years, also called […]
An “expert voice” astrophysicist explains that the Big Bang is now the “vanilla Big Bang,” which is unpopular because it doesn’t explain all observations: The Big Bang model is our most successful explanation for the history of the universe that we live in, and it’s ridiculously easy to encapsulate its core framework in a single, […]
