"textContent": "A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus. This exotic state may reveal how mass is generated, suggesting that particles can weigh less when surrounded by dense nuclear matter. The findings support long-standing theories about how the vacuum of space influences mass.",
