(via Sabine Hossenfelder) Physicists have come up with a new experiment to test the quantum twin paradox using a pair of atoms in a superposition. It's an interesting idea because it could tell us ...

A new study reveals that typically developing twins consistently take on the dominant role over their nontypically developing siblings, even after developmental gaps are resolved. By highlighting how ...

The way gravity affects the quantum realm has so far remained mysterious. But an experiment that uses lasers as a pair of tweezers could let researchers assess how Earth’s gravitational pull affects ...
