Neutron Star Glitches: Solved in the Lab ⚡ экспресс
Original: "Superfluid $$^3$$He aerogel experiments as a laboratory neutron star analogue"
Lab experiments reveal how tiny whirlpools inside ultra-dense stars cause their sudden speedups.

Inside ultra-dense neutron stars, weightless quantum vortices exist. Sometimes they break free, and the star-top jerks forward. Lab experiments with helium 'glass' show that these glitches can be predicted — meaning soon we'll be listening to pulsars like a cosmic radio broadcast.
🎯 A typical glitch changes the star's rotation period by one billionth of a second. To put it in perspective: if Earth jerked like that, the day would lengthen by a hair, but the planet itself would crack from the stress.
🎬 In David Brin's novel 'Startide Rising', intelligent beings live on a neutron star, exploiting its complex rotational dynamics.
