The Most Precarious Day in the Universe

SMRTR summary

On September 1, 1939, as Hitler invaded Poland, the journal Physical Review published two groundbreaking papers: Oppenheimer and Snyder described a star collapsing into a black hole with no stopping point, while Bohr and Wheeler showed how splitting an atom releases massive energy and triggers chain reactions. Both discoveries revealed that nature has tipping points — moments where collapse becomes unstoppable — mirroring the world's political catastrophe unfolding that same day.
