Description: The Big Bang is the currently accepted theory for the origin of the universe, however there are some who point to the existence of a very old star– called the Methuselah star– which is said to be even older. If that were true, this would imply that the Big Bang theory is wrong. In this video, Fermilab’s Dr. Don Lincoln explains how Big Bang deniers have gone astray.   Have astronomers disproved the Big Bang? youtube.com/watch?v=aFs5cKiajto Estimate of the age of the Methuselah star using Hubble telescope data: arxiv.org/abs/1302.3180   Estimate of the age of the Methuselah star using Gaia telescope data: arxiv.org/abs/1407.7591 Fermilab physics 101: fnal.gov/pub/science/particle-physics-101/index.html Fermilab home page: fnal.gov
