Best thing I’ve read in ages, thank you!

"There's a story that someone ran into an old physicist at a conference and asked him "How's your wife?" To which the physicist replied "Compared to what?""

My bad – Planck mass isn't at all what I thought it was, and that value is correct! Apparently it's just a coincidence it feels "macroscopic" to us (and hence confusing to me :)

So it's the heaviest point mass allowed by general relativity. The familiarity to us of the value is a coincidence.

Ohh snap – Planck mass isn't at all what I was thinking it is, 0.02 mg is roughly correct!

Apprently they’ve also redefined Planck mass :D

“In Feynman’s proposal, an object of Planck mass (0.02 mg) is placed in a quantum superposition of two locations before interacting gravitationally with another mass”
