Understanding Neutrinos: The Ghost Particles
Neutrinos are fundamental particles that are incredibly small and nearly massless, making them difficult to detect as they can pass through matter almost undetected. They are produced in various processes, including reactions in the cores of stars during supernovae and the interaction of cosmic rays with Earth's atmosphere. Despite their abundance, trillions of neutrinos pass through human bodies every second without causing any interaction, earning them the nickname 'ghost particles.' This unique property highlights their elusive nature and the challenges scientists face when studying them.
