Recent discussions in the scientific community have centered around the intersection of quantum mechanics and gravity. Dr. Zach Weller-Davies and his UCL co-authors have published an article in Nature Communications, focusing on testing gravity's quantum nature by measuring 'wobbles' in spacetime. The Stern-Gerlach experiment, conducted in 1922, has been highlighted as a pivotal moment in revealing the quantum world. Various physicists, including Avi Loeb and Jonathan Oppenheim, have expressed skepticism and alternative viewpoints on quantum gravity, with some proposing theories to unite Einstein's gravity with quantum mechanics. These discussions reflect the ongoing debate and exploration in the field of physics.
Gravity might be classical, not quantum, physicist Jonathan Oppenheim suggests. https://t.co/F8jAvPq0yr
Efforts to create a theory of quantum gravity are a perpetual hot topic in physics. But one researcher thinks gravity might be classical, after all. https://t.co/F8jAvPq0yr

The (Often) Overlooked Experiment That Revealed the Quantum World: "A century ago, the Stern-Gerlach experiment established the truth of quantum mechanics. Now it’s being used to probe the clash of quantum theory and gravity." https://t.co/rma9TDyym5 https://t.co/PzF72iad3h
Good to see Avi Loeb skeptical of David Grusch's claims about "extra dimensions and the holographic principle of string theory, both being highly questionable concepts for which there is no experimental evidence whatsoever. Quantum gravity effects of this type have nothing to do… https://t.co/WHbTuLNHP5
A 1922 experiment by the German physicists Otto Stern and Walther Gerlach offered an early glimpse of the quantum world, changing physics forever. @savagitsky details the history of the experiment and its influence on science today: https://t.co/uhqcnQTvyf
Congrats to Dr Zach Weller-Davies and his UCL co-authors for their @NatureComms article on testing gravity's quantum nature by measuring 'wobbles' in spacetime through tiny fluctuations in an object's weight ⚛ Now Zach's working in @InstaDeepAI's Research Team on our Quantum… https://t.co/OeLdXc07aD https://t.co/N9uPOKpKpX
