Neutrinos, elusive particles integral to the Standard Model of particle physics, have long posed a mystery since their inception in 1930. Detected directly in the 1950s, their significance extends beyond being candidates for dark matter. The recent KATRIN experiment has provided groundbreaking constraints on the electron neutrino's mass, showing it cannot exceed 0.45 eV/c². This discovery is crucial for understanding their role in cosmic energy density, the early Universe, and ultimately elucidating the fundamental nature of reality itself.
Neutrinos, once a candidate for dark matter and part of the Standard Model, have perplexed scientists since their proposal in 1930 as a solution to energy conservation puzzles.
The KATRIN experiment has achieved a groundbreaking result, placing tight constraints on the mass of the electron neutrino, crucial for understanding the Universe’s energy density and fundamental physics.
