INTRO: In 1867, Lord Kelvin imagined atoms as knots in the aether. The idea was soon disproven. Atoms turned out to be something else entirely. But his discarded vision may yet hold the key to why the universe exists.

Now, for the first time, Japanese physicists have shown that knots can arise in a realistic particle physics framework, one that also tackles deep puzzles such as neutrino masses, dark matter, and the strong CP problem. Their findings, in Physical Review Letters, suggest these “cosmic knots” could have formed and briefly dominated in the turbulent newborn universe, collapsing in ways that favored matter over antimatter and leaving behind a unique hum in spacetime that future detectors could listen for—a rarity for a physics mystery that’s notoriously hard to probe.

“This study addresses one of the most fundamental mysteries in physics: why our Universe is made of matter and not antimatter,” said study corresponding author Muneto Nitta, professor (special appointment) at Hiroshima University’s International Institute for Sustainability with Knotted Chiral Meta Matter (WPI-SKCM2) in Japan.

“This question is important because it touches directly on why stars, galaxies, and we ourselves exist at all.” (MORE - details, no ads)

From what I think I understand is that at the BB, in the first zillionth of a second, vast numbers of atomic scale BH’s were formed. Hawking radiation is a property of BH I believe. I read once where Hawking radiation says that the BH’s emit real particles with positive energy. How is positive energy different than positive charge? Would all the emitted particles be of positive charge, I assume so. If so, is there a reason no negative charge particles are emitted? Do BH’s for some reason reject positive charge particles/energy?

Classification of _X_ as either positive or negative energy seems to have to do with relational behavior conceptions in the context of gravitational fields and some quantum field effects. Rather than correspondence to charge.
