It should be no surprise that aging scientists from all fields gravitate (ha!) to astronomy as we get more interested in the grand fates of things. Fortunately there are many sites and channels to scratch that itch, giving us a perhaps too comfortable view of complex material. The life and death of stars is an example where the high level explanations of gravity versus fusion do work but where the many omitted details cause midnight befuddlement. Where does the energy come from? Where does it go? Wait… how fast – Relativistic speeds?
Anonymous Youtuber “But Why?” breaks the barrier with this beautiful video on the collapse of very big stars – the kind that leave neutron stars or black holes in their wake. It isn’t all symmetric implosions and classical rebounds and the thought of a giant object collapsing 5000-km in a tenth of a second boggles the mind. The depth of detail is breathtaking, the amount of research inspiring, and taught me much new physics that I incorrectly thought I already knew.
