What would Ettore say?

Nonlinear, nonlocal, nonHamiltonian interactions due to wave overlapping at short distances are always attractive in singlet couplings and as such, absorb coulomb interactions, resulting only in attractive interactions irrespective of whether the Coulomb contribution is attractive or repulsive.

Photons are doves.

Electrons have spin and valley isospin. They combine with their antiparticles to form particles which are their own antiparticles. This includes neutral pions, Cooper pairs, and positronium. Why can't people get the motorcycle analogy?

Nucleons, etc. are trucks.

My universe is different from the one you think you know

Electron-Like Scattering of Positronium
S. J. Brawley, S. Armitage,* J. Beale, D. E. Leslie, A. I. Williams, G. Laricchia

Positronium (Ps), a hydrogen-like atom composed of an electron and its antimatter partner, the positron, is formed in considerable quantities whenever positrons interact with matter. It has unexpectedly been found to scatter from a wide variety of atoms and molecules in a way very similar to that of a bare electron moving at the same velocity, despite Ps being neutral and twice the mass.
