DUNE: new detectors race to discover why the Universe exists
In a quest to understand why the Universe exists, scientists from the US and Japan are racing to study neutrinos and their antimatter counterparts, anti-neutrinos, which may hold the key to why matter prevailed over antimatter at the Universe's inception. The Deep Underground Neutrino Experiment (Dune) in South Dakota involves 1,500 scientists from 30 countries, who have constructed vast underground caverns to detect tiny changes in these sub-atomic particles as they travel from Illinois. Meanwhile, Japanese scientists are developing the Hyper K neutrino detector, a larger and more advanced version of their existing Super K, with plans to activate it ahead of the US project. Both initiatives aim to observe whether the changes in neutrinos and anti-neutrinos differ, potentially explaining why matter and antimatter did not annihilate each other entirely. Despite the competitive nature of the research, the first significant results are anticipated in a few years, with ongoing collaboration expected to yield a more comprehensive understanding of the Universe's origins.

Dive Deeper:
Inside a secluded laboratory in South Dakota, US scientists are delving 1,500 meters underground to access three massive caverns designed to shield sensitive equipment from exterior noise and radiation, crucial for studying neutrinos.
The Dune project, boasting a collaboration of 1,500 scientists from 30 nations, aims to uncover why matter exists by detecting changes in neutrinos and anti-neutrinos as they journey 800 miles between Illinois and South Dakota.
Neutrinos, created alongside matter and antimatter at the Universe's origin, are being scrutinized because their subtle differences in behavior might reveal why matter was not completely nullified by antimatter.
In Japan, scientists are advancing the Hyper K project, which features a larger and more sensitive neutrino detector than its predecessor, Super K, and plans to activate it sooner than the US-based Dune experiment.
Despite the competitive nature between the US and Japanese teams, collaboration is expected to enhance discoveries, as both projects aim to answer fundamental questions about the Universe’s formation and the existence of matter.
Dr. Linda Cremonesi from Queen Mary University highlights that while the Japanese project may activate first, it may not possess all necessary components to fully discern the behavior differences between neutrinos and anti-neutrinos.
The exploration into neutrinos is poised to be transformative, potentially altering humanity's understanding of the Universe and prompting further investigation into the mysterious conditions at the Universe's beginning.
