| Jun 6, 2019 at 20:16 | comment | added | Robin Ekman | Answers that do not point out that the premise of the question is blatantly false, as discussed in physics.stackexchange.com/q/126512, are extremely misleading. | |
| Jun 6, 2019 at 19:15 | comment | added | JMac | @DavidWhite Vacuums are generally described as the absence of matter (classically). I don't think many people define matter as an absence of atoms specifically. | |
| Jun 6, 2019 at 18:58 | comment | added | David White | Atoms are mostly empty space, and a vacuum is the absence of atoms. It is invalid to conclude from these two facts that atoms are mostly vacuum. | |

| Jun 6, 2019 at 18:51 | comment | added | rob♦ | "Mostly vacuum" suggests a mental model where electrons are "small," but that's not really how size works in quantum mechanics. | |

| Jun 6, 2019 at 14:29 | comment | added | Kaz | What is "vacuum"? An electron is not simply a hard little ball made of non-vacuum; it has further vacuum in it! | |
| Jun 6, 2019 at 14:29 | comment | added | Kyle Kanos | Basically the same thing as physics.stackexchange.com/q/126512/25301 | |

| Jun 6, 2019 at 6:06 | comment | added | PM 2Ring | @Maxim That's only tangentially related to this question. We do have some questions on that topic, eg physics.stackexchange.com/q/16048 We think that quarks & electrons are fundamental, but it takes huge energy to probe matter that deeply, so it's not easy to get relevant experimental data. | |

| Jun 6, 2019 at 5:15 | comment | added | Maxim Umansky | It looks like at any spatial scale the same pattern repeats: there are hard "cores" that interact with each other by fields, so between the cores there is vacuum. Matter is made of molecules that interact by electric forces. But you look at a molecule and see that it is made of atoms (also interacting by electric forces). Then you zoom in on an atom and you'll see there are nuclei and electrons there. Then you look at a nucleus and find that it is made of protons and neutrons. But those nuclons are made of quarks that interact with each other by some fields. Does the same pattern continue? | |
