In at least one case, an antielectron began orbiting an antiproton and created - briefly - antihydrogen.
These negative-state particles came to be thought of eventually as antiparticles-an antielectron and an antiproton- and it was not difficult to imagine that, just as protons and electrons made up matter, so antiprotons and antielectrons, if they actually existed, would make up antimatter.
