Stability, Instability, Drama, and How We are Space...

EVSN: Escape Velocity Space News ·

2024/03/07

It is possible to buy stickers, sweatshirts, mugs, and other stuff and things emblazoned with the simple phrase, “We are star stuff”. This phrase was popularized by Carl Sagan, and it serves as a gentle reminder that all the complex atoms - by which I mean most everything heavier than helium - found their start either in the nuclear core of a star or in the nuclear explosions of a dying star or stars. But, as with so many things, the truth is much more complicated than the meme.
