May 12, 2019 at 16:06 | comment | added | Árpád Szendrei | @Exocytosis The other answers are talking about point particles like the electron. I am talking about composite particles, like the proton and atom. Maybe I will ask a separate question about the strong force and dark energy. | |
May 12, 2019 at 5:11 | comment | added | Winston | I don't understand why you would ask if matter expands in your next question if you answer here that it does not. Any reason? | |
