A neutrino mass mismatch could shake cosmology’s foundations
SMRTR summary
Neutrinos, lightweight subatomic particles, play a crucial role in shaping the universe's structure. Recent data from the Dark Energy Spectroscopic Instrument (DESI) suggests neutrino masses may be unexpectedly small, possibly even zero or negative, challenging current understanding of physics. This discrepancy between cosmological observations and particle physics experiments could lead to new theories about the nature of neutrinos and dark energy.
