Dark matter and antimatter
Added 2022-04-18 07:34:34 +0000 UTCVery often there is a substitution of the concepts of "antimatter" and "dark matter".
Antimatter is, quite simply, an ordinary, familiar to us electron, only with a positive charge sign, they call it a positron.
Dark matter is a completely different kind of matter.
Such matter interacts only gravitationally.
