Hawks life!

A bold new theory says the universe may exist because of knots.

Japanese physicists just dropped a mind-bending idea that might finally solve one of cosmology’s biggest mysteries: why there’s something instead of nothing.

Right after the Big Bang, the laws of physics say matter and antimatter should have been created in perfect 50–50 balance. When they touch → total annihilation. Poof. Universe over before it started.

Yet here we are. The only reason anything exists is that, for every billion antimatter particles, there was one extra matter particle left over. That microscopic surplus built every star, planet, and person.

A new theory from a team in Japan says the answer lies in “cosmic knots”: ultra-stable, topologically twisted loops of pure energy that formed in the infant universe.

By uniting two deep symmetries in particle physics — B–L (baryon-minus-lepton number) and the Peccei–Quinn symmetry tied to axions — they show these knots naturally emerge, dominate the energy budget for a fleeting moment, then quantum-tunnel apart.

When the knots finally unravel, they spit out massive right-handed neutrinos that decay asymmetrically, handing matter the decisive victory over antimatter. Baryogenesis, solved in one elegant stroke.

Best part? The violent un-knotting should have blasted a unique pattern of gravitational waves across spacetime — a smoking-gun signal that future space detectors like LISA and DECIGO might actually hear.

The universe, it turns out, may owe its very existence to a few primordial knots coming undone.

Paper just out — physicists are already running simulations to test it.

@SLBarometer Love the discussion @SLBarometer ! Keep talking 💓

@prifernando53 @SLBarometer I do believe language can play a part in mistrust between communities, but there's deep-rooted mistrust that has historical connotations when it comes to what's happening in Sri Lanka.

No #tsunami threat to Australia from #earthquake felt in Melbourne, Victoria (magnitude 4.6 near Rawson, VIC). See https://t.co/Tynv3ZQpEq.
