Antimatter is classified as another form of matter, primarily composed of positrons and antiprotons, and is not inherently more exotic than ordinary matter. The interaction between matter and antimatter results in mutual annihilation, producing gamma rays. Current theories suggest that antimatter experiences gravity similarly to ordinary matter, although experimental evidence is lacking. The AEGIS experiment at CERN aims to investigate gravitational effects on antihydrogen, which has been produced since 2002.
PREREQUISITESPhysicists, researchers in particle physics, and anyone interested in the fundamental properties of antimatter and its gravitational interactions.
It is another form of matter and is no more exotic than ordinary matter. The most common form consists of positrons. There isn't much around, since contact of an antimatter particle with its matter counterpart results in mutual destruction, ending up as gamma rays.chis said:Antimatter excotic particle or another reality?
Is it a mirror of matter or just another form of matter?
Raap said:Is it known if matter attracts antimatter( and vice versa ) via gravity? From what I could find googling it, there was no actual experimental evidence of this.
Antimatter, in the form of antihydrogen, has been made at CERN since about 2002. It is in the form of antiprotons and positrons. No gravity/antigravity measurements have been made yet, but that is one of the oblectives of the AEGIS experiment. Seechis said:Antimatter excotic particle or another reality?

One BIG problem with testing the weak equivalence principle is that gravity is incredibly weak and electrical charges can swamp any gravitational effects. At CERN, they intend to produce cold, neutral antihydrogen to minimize noise from charge effects so gravitational equivalence can be tested. That's a big test.Bob S said:Antimatter, in the form of antihydrogen, has been made at CERN since about 2002. It is in the form of antiprotons and positrons.
