A magnet in space to understand the Dark Matter returns novel information of Cosmic rays

Prof Samuel Ting from MIT who won the Nobel Prize in 1976, says that when primary cosmic rays run through interstellar space, this unknown media releases its own cosmic rays into space. However to study these secondary cosmic rays, one would need to put a magnetic device in space such as the Alpha Magnetic Spectrometer on the International Space Station since charged cosmic rays get absorbed by the atmosphere. Prof. Ting says that by carefully measuring the matter and anti-matter arriving with the secondary cosmic rays, we could understand the biggest mystery of the universe as to why most of it is made up of only matter.
