A Peculiar Protected Structure Connects Viking Knots to Quantum Whirlpools

In Borromean rings, each circle holds the pattern together as it passes through the other two circles. Credit: Alexandr Kakinen / Aalto University Scientists have shown how three vortices can be connected in a way that prevents their dismantling. The bond structure resembles a pattern used by the Vikings and other ancient cultures, although this …

Cosmic chocolate pralines: surprising discovery of physicists on the structure of neutron stars

Studying the speed of sound has revealed that heavy neutron stars have a hard mantle and a soft core, while light neutron stars have a soft mantle and a hard core – much like different chocolate pralines. Credit: Peter Kiefer and Luciano Rezzolla Physicists are modeling more than a million equations of state to uncover …
