A avut Einstein dreptate? O teorie care poate schimba fizica a fost confirmată după un secol: Faza cuantică a gravitației, observată pentru prima dată

An international research team has confirmed Einstein's equivalence principle in quantum mechanics by observing gravitational effects on a freely falling quantum object. The study, published in Science Advances, utilized ultra-cold atoms in a quantum state to follow two simultaneous trajectories. Using the Quantum Galileo Interferometer, researchers measured changes in the quantum state of atoms, aligning with Einstein's predictions. This experiment bridges fundamental theories of gravity and quantum mechanics, suggesting future experiments could involve heavier objects like nanodiamonds.
