Like how can there be an anti-particle for a neutron, if it has no charge? And can there be an “anti-person” that’s made purely of antiparticles (positrons and antiprotons)?
In: Physics
A neutron is a composite particle made up of an up quark and two down quarks. So an anti-neutron would be made of an anti up quark and two anti down quarks. All particles theoretically have anti particles though, at least in the case of a photon, it is its own anti particle.
Theoretically, anti matter physics and chemistry would operate the same as our own.
