Gravitational memory as a defect in the fabric of spacetime ⚡ экспресс
Original: "Weyl Cosserat Elasticity and Gravitational Memory: An Effective Microstructured Model of Spacetime"
After gravitational waves pass, spacetime is forever changed, forming defects similar to dislocations in crystals.

After a gravitational wave, spacetime may not return to its original state — it stretches slightly, forever. Scientists have linked this 'memory' to tiny defects, like cracks in a crystal. This opens a new way to glimpse the hidden past of the Universe.
🎯 The very idea of gravitational memory emerged back in the 1970s, but directly detecting this effect remains a challenge — the expected shift is too small.
