| Oct 23 at 15:25 | comment | added | DrChinese | @Flamethrower As I mention, the quantum explanation of charge attraction and repulsion is complex and outside the scope of your reasonable question. I might suggest this SE post as a way to get better insight, and it includes some additional references. physics.stackexchange.com/questions/57874/… | |
| Oct 23 at 15:00 | comment | added | Flamethrower | Then how do particles receive the information of where they need to go? | |
| Oct 22 at 15:57 | comment | added | DrChinese | @Flamethrower Although photons do carry momentum, I would say the answer is no. A photon is its own anti particle and does not otherwise have any kind of observable that would relate to charge directly. | |
| Oct 22 at 13:09 | comment | added | Flamethrower | All practical limitations aside, I guess my ultimate question was "does the direction of photons encode the direction of the attraction/repulsion they carry?" | |
| Oct 20 at 9:00 | comment | added | James | (+1) Could you elaborate "EM field are relatively short range, most of the effect occurs on a distance on the order of an atom or molecule" please? Suppose 2 electrons are stationary 1 meter from each other, will they remain stationary for a long time at this distance, since the electromagnetic force of a single electron has decayed too much by 1 meter to have any accelerative effect on another electron at this distance? | |
| Oct 18 at 17:32 | comment | added | DrChinese | How exactly are you going to create a “micro” black hole that is smaller than an atomic radius, influences photon path, but doesn’t suck the electrons out of the atom? Man-made black holes currently don’t exist. But you can get an idea of the issues in this Scientific American piece: scientificamerican.com/article/…. | |
| Oct 18 at 17:16 | comment | added | Flamethrower | Well, of course, we would be speaking of something like a micro-black hole. | |
| Oct 18 at 13:53 | comment | added | DrChinese | @Flamethrower Gravity is so weak compared to the EM force that it be ignored, even if virtual photons are affected by it. You can’t vary gravity enough to see any effect. Virtual particles are created in pairs and usually annihilate very quickly. They cause a field effect that results in what we call the EM force. This description is very simplified, there are entire books about the details. So there really are no photons traveling from a proton to an electron in the normal sense. | |
| Oct 18 at 6:31 | comment | added | Flamethrower | What about the gravitational option? And do you mean to say that virtual photons don't travel directly from one particle to the other? | |
