what is antimatter? Does it exist? How does it matter to us?
In: Physics
Antimatter is like matter, but with almost all properties equal but flipped. Where for matter something would be a plus, for antimatter it’s a minus. The one exception is mass, sadly we have not discovered negative mass here, it’s exactly the same as matter.
Because of that, when a particle and it’s antiparticle (the have to match) meet, they cancel eachother out and annihilate. All that’s left is some energy in the form of light.
And yes, it exists, it’s regularly produced by some natural decays as well as made in particle colliders. There’s just very, very little made in this way.
