(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 ...

Science is redefined day in and day out, with new experiments pushing the boundaries of reality and existence. The Greenberger–Horne–Zeilinger (GHZ) paradox detailed how quantum theory can not be ...

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 ...

A team of physicists affiliated with multiple institutions in China has measured a pulse of light in 37 dimensions. In their paper published in Science Advances, the group explains that their ...
