What colour are electrons?

For Science!

This isn’t the flippant question it may look like.

“Colour” is a property of subatomic particles, a lot like electrical charge. It has absolutely nothing to do with colour in the normal sense. Just as charge leads to interactions via electromagnetic forces, so colour leads to interactions via so-called strong forces.

Taking that back another step: there are four fundamental forces of nature. The two of them that you are extremely familiar with are the electromagnetic and gravitational forces. These are long-range forces; they act over large distances. The other two, the weak and strong forces, act on the atomic and subatomic scale, so you only encounter their effects in a very indirect way. The strong force is particularly important as it’s the force that sticks the protons and neutrons in the nuclei of atoms together. (You wouldn’t otherwise expect nuclei to stick together; the electromagnetic interactions are between positively…

Do electrons radiate all the time?


Seriously! The question in the title is not rhetorical. I cannot really answer the question. All I have is a bunch of ideas on electromagnetism. Anyone has any answers or simply wants to tell me, ‘your ideas are stupid’, please do, in the comments below.

Since the electromagnetic force is propagated by photons, is it possible to detect these photons and measure their characteristics(wavelength for example). Also is there a radiation pressure associated with each photon? Photons can interact with each other, so can the repulsion between 2 electrons be understood as the radiations from both “pushing” one another at the “mid-point” between them?
But if an electron continuously radiates then it should constantly lose mass. But isnt the mass of an electron a fundamental quantity?

Maybe photons given out by electrons are somehow different from those released by positive particles. Every electron while radiating energy into space constantly receives…

GJ Stoney“George Johnstone Stoney (15 February 1826 – 5 July 1911) was anAnglo-Irish physicist. He is most famous for introducing the term electron as the “fundamental unit quantity of electricity”.[1] He had introduced the concept, though not the word, as early as 1874 and 1881, and the word came in 1891.[2]  [3] [4] He published around 75 scientific papers during his lifetime.” from Wikipedia
