Precision measurements of an international research team on ultracold quantum gases provide results that could help to further read one of the last big puzzles on t3n.de

Gravity on a quantum scale: For the first time, physicists have measured the predicted quantum phase of a freely falling object directly. With around 20,000 ultracold rubidium atoms, the observed phase development up to a few percent agrees with the theoretical predictions. This is based on the application of Einstein's equivalence principle to quantum waves in the tested area, without quantizing gravity itself. Oxford [...] The article Einstein…

The result does not unify quantum mechanics and gravity, nor does it show that gravity itself is quantum, but is an important part of this effort.
