3 days ago · Their work leverages cutting-edge tools and techniques from quantum information theory and quantum optics to demonstrate the principles of gravity-mediated entanglement using particles of light, i ...
1 day ago · The theory was initially proposed by Dutch astronomer Jan Oort in 1932 to explain the so-called “missing mass” required for things like galaxies to cluster together. However, this theory is still as unresolved today as over a century ago.
Physicists announce new theory that unifies Gravity and Quantum Mechanics while preserving Einstein's concept of Spacetime Modern physics is based on two pillars. One is quantum theory, which governs the smallest particles in the universe. The other is Einstein's general theory of relativity, which explains gravity…
2 days ago · The Cassini mission, which orbited Saturn from 2004 to 2017, provided an opportunity to test MOND. Saturn orbits the Sun at 10 AU, and MOND predicts subtle deviations in Saturn's orbit due to the galaxy's gravity. Cassini measured the Earth-Saturn distance using radio pulses, but found no anomalies expected by MOND.
5 days ago · One way scientists study dark matter is by using something called gravitational lensing. Light going through a gravitational lens gets bent. When light from distant stars passes through a galaxy or cluster, the gravity of the matter present in the galaxy or cluster causes the light to bend.
5 days ago · (Dated: June 3, 2024) Christodoulou and Rovelli (CR) [1] have argued that a Bose et al.-Marletto-Vedral (BMV) exper-iment that confirmed the quantum nature of gravity would give laboratory evidence for a quantum superposition of spacetime geometries created in the course of the experiment.
5 days ago · Scientists have made dozens of attempts over recent decades to modify Einsteinian gravity to better fit observations. One of these is the theory of “massive gravity” proposed by Claudia de ...
