Ambiguity

I am uncertain about the discovery of this antiparticles .
This is a model describing the asymmetrical nature between the terrestrial matter and antimatter which also gains priority as a major unsolved problem in physics.
If antimatter will be considered to produce energy, it will be 100% efficient whereby nuclear fission is 1.5% efficient.
This is after CERN, the European organization for nuclear research, heuristically worked with particles of matter, trying to solve its asymmetrical nature by discovering its partner antimatter.
Will this energy solve the world or will be used to make deadly weapons?
