Anti-Matter and Anti Energy

Anti-Matter and Anti Energy

• 
  ‘Anti’ means the opposite. So anti-matter has some properties opposite with respect to the usual matter. 
  
  • 
    For example, the electron has as its antiparticle the antielectron. The electron and the antielectron have exactly the same masses, but they have exactly opposite electrical charges.
    
• 
  It is hypothesized that every elementary particle in the Universe has a partner particle, known as an ‘antiparticle’.
  
• 
  The particle and its antiparticle share many similar characteristics, but many other properties are the exact opposite.
  
• 
  The electron, for example, has as its antiparticle the antielectron. They both have the same masses, but they have exactly opposite electrical charges.
  
• 
  Most of the human understanding of anti-matter comes from high-energy accelerator experiments.
  
• 
  When a matter particle meets its antimatter particle, they destroy each other completely (i.e. annihilation), releasing the energy equivalent of their rest masses (following Einstein’s E = mc²).
  
• 
  For instance, when an electron meets an antielectron, the two annihilate and produce a burst of light which produces a corresponding energy level equivalent to the masses of the two particles.
