Nuclei, by the way, are the protons and neutrons (nucleons) stuck together in the centers of atoms. The number of protons a nucleus has tells you what kind of element it is (the atomic number); the number of protons + neutrons tells you the atomic mass.

One more thing: nuclear power plants are doing fission. Because it involves breaking up big nuclei, it creates smaller (but still heavy) nuclei that are themselves not so stable: nuclear waste. Hopefully we’ll one day produce fusion power plants which make less dangerous waste.

Nuke school flashback to 30 year old nuclear physics class memory. Forgot I knew that until you brought up iron as a peak in the energy curve.

What is special about iron that makes it the turning point?

It has something to do with a balance between the strong nuclear force holding the nucleons together and the electromagnetic repulsion between the protons but that’s about the extent to which I’ve looked into it.

How do gravitational waves escape from the collision of t2o black holes since the waves travel at the speed of light and black holes are black?

As a recovering nuclear theorist, I approve the idea of changing the name of the “curve of binding energy” to the “curve of clinginess.”

And that's why you can't *step* with iron...

Ahhh this is my research so i can't resist! I'd made a general schematic showing what happens to different layers of the star during the explosion, just sharing it here. Left to right goes from the center of the star towards the surface.pic.twitter.com/qMHyxSu0ZZ

This is great, thanks!
