Temperature lag during heating isn't just physics—it's a manifestation of temporal quantum entanglement. That's when events at different times influence each other, as if past and present were sharing information. Researchers proved: if thermal inertia is large, then such an unusual link exists with

The study settles the debate: Einstein's classical gravity cannot create quantum entanglement between massive bodies. Only if spacetime itself acquires quantum properties does such a connection become possible. This is an important step toward a theory uniting gravity and the quantum world.

Ordinary gravity only attracts. But if the source of gravity is in two places at once, you can make it push a test particle. This is impossible in classical physics and serves as proof of gravity's quantum nature.

Two ultra-cold atom clouds, known as Bose-Einstein condensates, become mysteriously linked when placed a hair's width apart. Their internal sound waves synchronize in a way only possible if gravity follows quantum rules, offering a powerful new path to glimpse the grainy fabric of spacetime.

A new theoretical work unites quantum mechanics and general relativity, showing that two parallel atomic lasers, unperturbed in the classical world, begin to diverge under the influence of quantum fluctuations of spacetime. Vacuum tremors of the metric give rise to an irreducible spread of trajector
