New Theory Connects Einstein's Relativity with Quantum Mechanics

Researchers at University College London propose a radical new theory suggesting that spacetime remains classical and unaffected by quantum mechanics, challenging the need to unify gravity and quantum physics by modifying Einstein's theory. Their approach could resolve longstanding paradoxes like black hole information loss and offers new experimental avenues to test the nature of spacetime, potentially transforming our understanding of the universe.

Gravity's Quantum Mystery: Exploring the Unification of Physics

Physicists are still grappling with the challenge of reconciling Einstein's general theory of relativity (GR) and quantum physics. Traditionally, efforts have focused on quantizing gravity to make it consistent with other quantum forces. However, a new approach called "postquantum" theory of classical gravity, proposed by Jonathan Oppenheim and his team, suggests that gravity may not be quantum at all. This idea challenges the assumption that gravity is inherently quantum and opens up new possibilities for understanding the behavior of particles and the nature of gravity. While the theory is still in its early stages and faces challenges, it offers a fresh perspective that deserves further exploration.

"Revolutionary Theory Proposes Unified Explanation for Gravity and Quantum Mechanics"

A group of researchers has proposed a new theory, called the "postquantum theory of classical gravity," in an attempt to bridge the gap between quantum mechanics and general relativity. Unlike previous contenders for a grand unified theory, this new theory does not quantize space-time. Instead, it suggests that quantum mechanics should be modified, leading to a breakdown of predictability at high precision. The theory predicts violent fluctuations in space-time, which can be tested by measuring the mass and weight of an object with high precision. If these fluctuations are not observed, the postquantum theory of classical gravity can be ruled out. Testing this theory could potentially be done within two decades.
