New Insights into Neutrinos and the Universe's Origins

Scientists from Indiana University and international collaborations have made significant progress in understanding why the universe is dominated by matter rather than antimatter, by studying neutrino behavior and their oscillations, which may violate CP symmetry and explain the cosmic imbalance. This breakthrough was achieved through joint analysis of data from the NOvA and T2K neutrino experiments, highlighting the importance of global scientific cooperation.

Unraveling the Universe's Existence through Helium Measurements in Distant Galaxies

Researchers using Japan's Subaru telescope have measured the amount and type of helium in distant galaxies, providing insights into the matter-antimatter asymmetry problem. The Big Bang should have created an equal amount of matter and antimatter, which would have annihilated each other, leaving the universe empty. However, the presence of matter suggests an imbalance. The study suggests that the number of neutrinos in the early universe was greater than the number of antineutrinos, potentially explaining the asymmetry. This finding offers a possible explanation for why the universe exists.
