Swaying quantum vacuum energy vs compelling charge

[“Models of the quantum vacuum” series] I read this article today “‘The Unknown Question’ — The End of Spacetime” (June 22, 2019) and watched the included YouTube videos. Something bothered me which I’ve been thinking about for years, namely, that even theoretical physicist Nima Arkani-Hamed sounded like he viewed the electron as like a spherical… Continue reading Swaying quantum vacuum energy vs compelling charge

The proton and perturbation problem

[Draft] [“Building a ‘verse” series] I’ve cited this physicist’s video elsewhere, but Perimeter Institute’s overview of her lecture includes a helpful characterization of perturbation theory in the context of understanding the proton better: “Phiala Shanahan builds the universe – with a new approach to calculations and the aid of supercomputers, Emmy Noether Visiting Fellow Phiala… Continue reading The proton and perturbation problem

Empty dumpty

[“Models of the quantum vacuum” series] A theoretical physicist walks into a bar. The bartender says, “What can I get you?” The physicist says, “Nothing.” The bartender gives the physicist an empty glass. The physicist says, “Thanks, that’s plenty!” Physicists take emptiness quite seriously. So-called empty space is an important area of study and research.… Continue reading Empty dumpty
