In fact, it has multiple properties that are so extreme that it almost certainly did NOT form in the way that we thought all white dwarfs formed. This one peculiar point of faint light may change our understanding of not just white dwarfs, but of all cosmology

Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder - or as the amount of useful work that you can get from it - or as the information hidden by the system. Despite the seeming ambiguity in its definition, many physicists hold entropy to be behind one of the most fundamental laws of physics. Entropy Explained
