When antimatter touches matter, they annihilate each other and convert part of their mass into energy, usually producing gamma rays and other particles. In plain terms, the contact does not make the antimatter “burn” like normal fuel; it triggers a particle-level destruction event with a lot of energy released very quickly.

What that means

  • Matter and antimatter particles have the same mass but opposite charge.
  • When they meet, they cannot coexist, so they annihilate.
  • The energy comes out as radiation and new particles, depending on what collided.

How dramatic is it?

Even a tiny amount can release a huge amount of energy because mass is being turned into energy. That is why scientists handle antimatter with electromagnetic traps so it never touches the walls of a container.

Simple example

If a positron meets an electron, both disappear as particles and their mass becomes energy in the form of gamma rays and related byproducts. That is the basic matter-antimatter reaction physicists mean when they talk about annihilation.

One-line version

Antimatter touching matter causes both to annihilate into energy almost instantly.
