Two teams working independently have conducted studies with similar results suggesting the possibility that some of the cosmic rays striking the Earth arise from dark matter particles colliding with one another. One group, a trio of researchers with RWTH Aachen University in Germany, created models simulating conditions both with and without dark matter-produced particles. The other group, a team with the Chinese Academy of Sciences, conducted a study involving the boron-to-carbon ratio in cosmic particles. Both teams have published their results in Physical Review Letters.
Part of the theory surrounding dark matter is the likelihood that if it does, indeed, exist, then it is likely that at least some of it is moving very fast, and if that is the case, then it seems logical to conclude that some of those particles might collide, causing them to break apart. If they do, the thinking goes, then it might be possible that other particles could result, some of which might be detectable. If scientists could detect such particles and were able to attribute them to dark matter, then they could prove that dark matter exists. To that end, the two teams involved in this latest research used data from the Alpha Magnetic Spectrometer (AMS) aboard the International Space station to conduct independent studies of possible dark matter particles.
