Generations of researchers have tried to create a quantum theory of gravity, and their work has produced sophisticated ...

Thanks to Einstein's theory of relativity, numerous tests have concluded tangible effects on how we on Earth record and ...

Notably, mediated entanglement represents a core principle of future experiments using massive particles, aiming to probe for the first time the quantumness of gravity.

Some theories, such as loop quantum gravity, suggest space and time may disappear at very small scales or high energies. If that’s right, it may not be possible to carry out experiments at these ...

Cavendish-like: A schematic diagram of the proposed experiment on gravitational interaction between two torsion balances. Two torsion pendula are placed with their equilibrium orientations (dashed ...

Work to do Tabletop experiments are very promising, but there is still work to do. The recent experiment comes close to the quantum domain, but doesn’t quite get there.

So, the experiment is designed to determine whether quantum entanglement occurs in the pair during freefall, when the force of the gravity between the diamonds is the only way that they interact.

Da Vinci's ideas about gravity preceded even Isaac Newton's formal announcement of the universal law of gravitation in 1687 and Galileo Galilei's law of parabolic fall, which dictates how objects ...

Is gravity a quantum phenomenon? That has been one of the big outstanding questions in physics for decades. Physicists have proposed an experiment that could settle the issue. However, it requires ...

Either gravity is a classical background in which quantum objects interact, or both gravity and objects are quantized. This proposed experiment could determine which approach matches reality.

By Michael Irving November 05, 2018 The ALPHA-g experiment being set up at CERN, which will drop antimatter to see how gravity affects it CERN View 1 Images ...
