• Ginestra Bianconi proposes gravity arises from quantum relative entropy, linking spacetime metrics to quantum operators encoding geometry.
• Melvin Vopson suggests gravity is a byproduct of the universe compressing information like a computer algorithm, based on the 'second law of infodynamics.'
• These theories, while speculative, offer potential new perspectives on quantum gravity, cosmology, and the fundamental nature of the universe, including the possibility of simulation.

Several new theories are challenging conventional understandings of gravity. One approach, developed by Ginestra Bianconi, posits that gravity arises from quantum relative entropy, connecting spacetime geometry with quantum information. Another theory, proposed by Melvin Vopson, suggests that gravity is not a fundamental force but an emergent property of a universe that behaves like a giant computer, optimizing information and minimizing entropy. These ideas have implications for quantum gravity, cosmology, and potentially, the simulation hypothesis.

• What: New theories on gravity propose it's either an emergent property of quantum information, a byproduct of information compression in a computational universe, or both.
• Who: Ginestra Bianconi (Queen Mary University of London), Melvin Vopson (University of Portsmouth), Erik Verlinde (Dutch Physicist).
• When: Research published in April/May 2025; Verlinde's theory proposed in 2011.
• Where: Theoretical research conducted at universities in London, Portsmouth, and the Netherlands.

These new theories offer intriguing perspectives on gravity and its relationship to quantum mechanics, information theory, and cosmology. Bianconi's approach grounds gravity in quantum information through quantum relative entropy, while Vopson's theory connects it to computational processes and entropy minimization. While both theories are still in early stages and lack experimental validation, they challenge existing paradigms and could potentially lead to new avenues of research in understanding the fundamental nature of the universe. The simulation aspect is highly speculative but adds another layer to the discussion.

Matter tells space how to curve, and space tells matter how to move.

My findings in this study fit with the thought that the universe might work like a giant computer, or our reality is a simulated construct. Just like computers try to save space and run more efficiently, the universe might be doing the same.

It's a new way to think about gravity – not just as a pull, but as something that happens when the universe is trying to stay organised.

The ongoing exploration of quantum gravity, encompassing theories like string theory and loop quantum gravity, signals a paradigm shift in theoretical physics, potentially unifying gravity with quantum mechanics. These emerging theories propose that gravity may arise from quantum information, entanglement, or computational processes, challenging the conventional understanding of spacetime. While still largely theoretical, these approaches offer tantalizing glimpses into the deep connections between gravity, information, and the fundamental structure of the universe, highlighting the importance of interdisciplinary approaches. Future research, including experiments like GQuEST, aims to detect observable signatures of quantized spacetime and validate these theoretical frameworks. Whether gravity arises from entropy, quantum information, or computational optimization, these theories emphasize the necessity of interdisciplinary approaches in unraveling the mysteries of the cosmos.
