Black Holes. Messages from the Edge of the Universe
Description
It is the birth of neutrino astronomy. For the first time, astrophysicists can detect extraterrestrial neutrinos in the ice in the South Pole. Neutrinos are the most common and also most mysterious elementary particles. Since these particles are invisible to us, their mass is unknown. Also, they are not electrically charged and rarely interact with other matter. Each of the tiny neutrinos is a potential messenger with information about its origin. Many discoveries in astrophysics have extended our idea of the cosmos, but the core questions of science remain unanswered: how did the universe come to be? What keeps our world together? Extragalactic neutrinos are keys to answering these questions.
