65 Billion Invisible Visitors Every Second #Neutrinos #Physics #Shorts

[00:00:00]Every single second, >> [music] >> 65 billion neutrinos stream through every square centimeter or 0.15 square inches of your body. Yet, [music] they leave absolutely no trace of their passage. These subatomic anomalies, forged in the crushing nuclear fusion cores of stars >> [music] >> and the violent cataclysms of supernovae, are governed almost entirely by the weak nuclear force. [music] Because neutrinos possess zero electromagnetic charge, they do not interact with the electron shells or the positively charged protons of normal baryonic matter. [music] If you were to construct a solid wall of lead measuring exactly one light-year in thickness, which is approximately 9.46 [music] trillion kilometers or 5.88 trillion miles, a neutrino would pass completely through [music] it without a single atomic collision. Their mass is so infinitesimally small [music] that physicists can only measure it through the observation of quantum flavor oscillations as they travel across the cosmos. This spectral behavior makes them the ultimate cosmic messengers, [music] carrying pristine, unaltered data directly from the heart of our sun and the most distant [music] ancient galaxies in the observable universe.
