Story summary

A team of physicists from Japan and Germany revived Lord Kelvin's 1867 knot concept in modern particle physics, proposing a knot-dominated era after the Big Bang influencing matter-antimatter asymmetry.
The model uses Baryon Number Minus Lepton Number (B-L) and Peccei-Quinn (PQ) symmetries, predicting knot collapse generated right-handed neutrinos that decayed to favor matter.
Gravitational waves from LISA and DECIGO could test the idea, reshaping views on the universe's origins.
