Invisible Waves Make a Plate Ring ⚡ экспресс
Original: "Relativistic Elastic Response to Gravitational Waves: Explicit Solutions for a Rectangular Plate"
Solid bodies can vibrate under the influence of gravitational waves—ripples in spacetime itself.

A thin metal plate in a vacuum can start trembling on its own—if a gravitational wave passes through it. Physicists found exact formulas for such vibrations and figured out how much energy gets deposited in the material from these cosmic disturbances.
🎯 Cork is one of the few natural materials with a Poisson’s ratio close to zero. This is exactly what makes it ideal for sealing bottles: when compressed, it hardly expands sideways.
