How do I know I am not looking at anions?
How do I know I am not observing free electrons annihilating?
Quote from: Thebox on 22/02/2018 16:55:54How do I know I am not looking at anions? because there are no nuclei present in a vacuum.Quote How do I know I am not observing free electrons annihilating? because the annihilation of a free electron produces a single photon of 511 keV, not a picture on a cathode ray tube.This stuff is all in the textbooks - why not read one?
A lepton is an elementary, half-integer spin particle that does not undergo strong interactions. Two main classes of leptons exist: charged leptons, and neutral leptons. Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.
From Wikipedia (since you don't like books) Quote A lepton is an elementary, half-integer spin particle that does not undergo strong interactions. Two main classes of leptons exist: charged leptons, and neutral leptons.

On this planet, most scientific discussion is carried out in English using common definitions that scientists learn at school.
You may call this CMBR. The rest of us call it garbage.

I noticed you ignored any questions as per normal. If your questions are based on a total misunderstanding of science then, at best they are not worth answering. In many cases there will be no answer.Have you found out what the circumstances are in which electrons are annihilated?And that is a matter of physics, not matter how hard you try to ignore it.
Electrons are not generally annihilated. They only do that if they interact with a positron.That's what the physics tells you.But positrons are rare, so annihilation doesn't usually happen.So, back to your earlier mistake, do you now realise that electrons do exist outside of atoms?
