China has built a $300 million underground detector to study neutrinos, tiny particles that may hold clues to the universe's mysteries.
China has launched a new underground detector to find out neutrinos, a tiny particle that can help scientists understand how the universe works. The facility costs $300 million, and it's set to begin operating in the second half of 2025. Looking UP into the sky, what's behind the clouds is the boundless, mysterious universe that we, as humans, still have many questions about.
And in order to figure out how the universe evolved, this group of Chinese scientists decide to look DOWN and go underground. They have built a massive detector 700 metres underground in southern China, just to look for neutrinos, a TINY particle that can help answer questions of the BIG universe. Cao Jun is the director of Institute of HIgh Energy Physics and deputy project manager of the Jiangmen Underground Neutrino Observatory, or JUNO.“So neutrinos is one of fundamental particles that consist our matter world. Because it barely interacts with other matters, so up to now it’s the least understood particle in our world. That’s why we need to study it. We highly suspect neutrino may associate with several long-existing puzzles in our universe.” The existence of neutrinos was discovered almost a century ago, but currently, research about the particle is still its early stage. So far, it's been found that neutrinos date back to 13.8 billion years ago, when the universe expanded from a single, tiny point with extremely high temperature and density. Scientists have speculated that many particles were present during this period, which is better known as the 'Big Bang'. But unlike other particles, neutrinos rarely interact with other particles, making them very difficult to detect, or measure. And that's why scientists are now turning to this giant, underground detector in Kaiping, China for help.
