A new experiment using ultracold rubidium atoms found that a quantum object in free fall behaves consistently with Einstein's ...
An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted ...
Scientists at the University of Ulm, the University of Oxford, and the Ben-Gurion University ...
Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...
Physicists observed a quantum state change in ultracold atoms. This change matched Einstein's equivalence principle for a ...
Quantum mechanics and Einstein’s theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them. A new theoretical framework suggests that some ...
The weak equivalence principle (WEP) is central to Einstein's general relativity. It posits that gravity must accelerate ...
There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.
