Technically speaking, antimatter would be the aggregation of antiparticles. Being antiparticles the opposite charge analogous particles, that is, f.i. the positron (a positively charged electron) or the antiproton (a negative proton), which occur in the Universe in a smaller amount compared to the particles, and that when mixed with "normal" matter annihilate each other, producing vast quantities of high-energy photons and other particle-antiparticle pairs (such as the neutrino-antineutrino).’
We all know from our sensorial experience that the matter is everywhere in the known Universe in considerable masses, but the antimatter seems …

MINERvA is a complex device built at DOE’s Fermi National Accelerator Laboratory to observe the interactions of neutrinos (v) and is the first phase of functioning with 24 modules already assembled and working.
Right now, MINERvA has been able to catch a glimpse of how the neutrinos interact with the matter. The deadline for the full assembly is 2010, in which 109 2 inches-thick modules will be working to observe the neutrinos, provided by the Fermilab Accelerator Complex.
