What is Antimatter?


The Basics:

  • Antimatter has a lot in common with regular matter.

  • Both matter and antimatter are substances that have mass, take up space, and generally consist of subatomic particles.

  • The main difference between matter and antimatter is that antimatter is made out of antiparticles that correspond to the particles of ordinary matter.

  • Sub atomically, antimatter is just a mirror image of regular matter.
