Big Bang
Researchers propose that knotted structures in the early universe could account for why matter dominates over antimatter. By combining two symmetries in particle physics, these cosmic knots formed after the Big Bang, briefly dominated cosmic energy, and decayed to produce a slight matter surplus. The model also addresses neutrino masses, dark matter, and the strong CP problem.

Researchers at Rice University have captured the temperature profile of quark-gluon plasma, the ultra-hot matter from the universe's dawn. By analyzing electron-positron emissions from atomic collisions, they determined precise temperatures at different evolutionary stages. The findings, published in Nature Communications, refine understanding of early cosmic conditions.
