Physicist’s 150-year-old knot hypothesis could hold the key to why the universe exists

Japanese physicists have revived Lord Kelvin's 1867 knot theory to explain why the universe contains far more matter than antimatter, despite the Big Bang theoretically producing equal amounts. Their study suggests "cosmic knots" in early spacetime collapsed in ways that favored matter creation, potentially solving this fundamental mystery of existence. These ancient knots may have left detectable gravitational wave signatures that future space observatories could record.
