全宇宙最普遍、卻又最難捉摸、最不為人所認知的粒子是什麼？是中微子。自從人類發明核彈開始，已耗資數十億元在捕捉這種人稱「幽靈粒子」的中微子。中微子與原子的數量比例是十億比一，但它們很少與其他東西互動，還會以三種不同形態存在，神出鬼沒。中微子到底是甚麼？今集，團隊會聯同一班來自世界各地的中微子獵人，嘗試捕捉中微子的第四形態，而調查結果或會逼使科學家重新繪製亞原子世界的藍圖、重新定義物理學的標準模型，與及改變我們對宇宙運作的認知。

電視版本：雙語廣播（粵語／英語）

What’s the most common—yet most elusive and least understood—particle in the universe? The neutrino. Starting with the invention of the nuclear bomb, billions of dollars have been spent in pursuit of this so-called ghost particle. Outnumbering atoms a billion to one, neutrons are preposterously plentiful, they hardly interact with anything, and they mystifyingly morph between three different forms. What’s going on here? NOVA joins an international team of neutrino hunters as they try to capture an elusive fourth form of neutrino. The results of their investigation may force scientists to redraw their well-established blueprint of the subatomic world, the Standard Model of physics, and change our understanding of how the universe works.
