“Cosmic Neutrinos Can be Absorbed by Planet Earth”

 Scientists using the IceCube Observatory located near the South Pole have discovered that neutrinos can be absorbed by our Planet Earth. With almost no mass and no charge, these particles rarely interact with matter. Yet tens of trillions of neutrinos pass through our bodies every second.  Previous theories predicted that at high energies, neutrinos can be expected to interact with matter and be absorbed by the Earth instead of passing through the planet.  “We knew that lower-energy neutrinos pass through just about anything, but although we had expected higher-energy neutrinos to be different, no previous experiments had been able to demonstrate convincingly that higher-energy neutrinos could be stopped by anything,” said Penn State Professor Doug Cowen. “However, the neutrino does have a tiny probability to interact, and this probability increases with energy. That probability is what scientists call the neutrino cross section.”  The new measurements recorded by IceCube determined the neutrino cross section energies to be about 6.3 TeV and 980 TeV, energy levels significantly higher than previously measured.
