Physicists have proposed a radical approach that questions decades of belief about how gravity, spacetime, and quantum mechanics might fit together.
They have introduced a theory that keeps the classical concept of spacetime as envisioned by Einstein, even as it addresses a long-standing rift in modern physics.

The quantum mechanics of betraying everyone and no one at the same time.
Quantum computing has long struggled with creating entangled photons efficiently, but a team of researchers has discovered a game-changing method using metasurfaces—flat, engineered structures that control light.
By leveraging these metasurfaces, they can generate and manipulate entangled photons more easily and compactly than ever before. This breakthrough could open the door to smaller, more powerful quantum computers and even pave the way for quantum networks that deliver entangled photons to multiple users.

AI has helped physicists discover a simpler way of achieving quantum entanglement. This finding could make it easier to develop quantum communication technologies.
Physicists have long attempted to find a single theory that unites quantum mechanics and general relativity.
This has been very tricky because quantum mechanics focuses on the unpredictable nature of particles at microscopic scales, whereas general relativity explains gravity as the curvature of spacetime caused by massive objects.
The two theories discuss forces existing on different scales. Bianconi employed an interesting approach to deal with this challenge. She proposes an entropic action where, instead of being a fixed background, spacetime works like a quantum operator — acting on quantum states and deciding how they change over time.
The behaviour of quantum fields in curved spacetime is simulated using a two-dimensional trapped quantum gas of potassium atoms with a configurable trap and adjustable interaction strength.
During the study, the engineers used the quantum property to track the electrical activity of the heart muscles and cells.
About 100 trillion neutrinos are passing through your body at this very second. The particles are the second most abundant form of matter in the universe (behind light), but they interact very, very rarely. That property makes them ideal objects for studying the fundamentals of quantum mechanics; however, it also complicates measurements.
For example, neutrinos were discovered in the 1950s, but their properties are still obscure. New research, published in Nature by a team including Lawrence Livermore National Laboratory (LLNL) scientists, introduces an experimental technique to constrain the size of the neutrino’s wavepacket.
Imagine measuring a neutrino like finding a needle in a haystack. The particles are so elusive that, previously, researchers didn’t even know where on Earth the haystack was located. Now, they’ve identified the haystack, or, scientifically, the size of the neutrino’s “wavepacket.” This measurement doesn’t say exactly where the neutrino is located or how big it is, but it does constrain what those answers could be.
“Information and the Nature of Reality: From Physics To Metaphysics” by Paul Davies and Niels Henrik Gregersen Book Link: https://amzn.to/41GMVl6 (Affiliate link: If you use this link to buy something, I may earn a commission at no extra cost to you.) Playlist: • Two AI’s Discuss: The Quantum Physics… This collection of essays, “Information and the Nature of Reality,” explores the evolving role of information from physics to metaphysics. It examines how the concept of matter has shifted historically, particularly with advances in quantum physics, and considers materialism’s limitations as a worldview. The texts propose that information may be as fundamental as matter and energy in understanding the universe, investigating its influence on biology, consciousness, and computation. Several contributions consider the theological implications, pondering God as an ultimate source of information and discussing the relationship between divine action and natural processes. Ultimately, the text argues for interdisciplinary dialogue between science, philosophy, and theology to form an adequate theory of the natural world. • Paul Davies and Niels Henrik Gregersen in the introduction introduce the central question of whether information matters in understanding reality, setting the stage for the book’s interdisciplinary exploration. • Ernan McMullin traces the historical evolution of the concept of matter in philosophy and its relationship to physics in his essay. • Philip Clayton in his contribution, Unsolved dilemmas: the concept of matter in the history of philosophy and in contemporary physics, explores the persistent challenges and transformations in understanding matter across philosophical history and modern physics. • Paul Davies in Universe from bit discusses the idea that the universe may fundamentally be based on information. • Seth Lloyd in The computational universe presents the concept of the universe as a vast quantum computer. • Henry Stapp in Minds and values in the quantum universe examines the role of consciousness and values within the framework of quantum mechanics. • John Maynard Smith in The concept of information in biology investigates the application and implications of information concepts within biological systems, particularly in genetics and evolution. • Terrence W. Deacon in What is missing from theories of information? argues that the crucial aspect of information is its inherent reference to something absent. • Bernd-Olaf Küppers in Information and communication in living matter explores the semantic dimensions of information and its fundamental role in biological processes. • Jesper Hoffmeyer in Semiotic freedom: an emerging force proposes a biosemiotic perspective, emphasizing the importance of signs and interpretation in understanding life. • Holmes Rolston, III in Care on Earth: generating informed concern examines the evolutionary basis and significance of caring and concern in the natural world. • Arthur Peacocke in The sciences of complexity: a new theological resource? explores how the sciences of complexity can offer new insights for theological understanding. • Keith Ward in God as the ultimate informational principle posits that God can be understood as the fundamental source and sustainer of information in the universe. • John F. Haught in Information, theology, and the universe explores the relationship between information, theology, and our understanding of the cosmos. • Niels Henrik Gregersen in God, matter, and information: towards a Stoicizing Logos Christology proposes a theological framework that integrates the concepts of God, matter, and information, drawing on Stoic philosophy and Christian theology. #InformationReality #PhysicsMetaphysics #NatureOfReality #QuantumInformation #BiologicalInformation #PhilosophyOfScience #ScienceAndTheology #CosmicInformation #OriginOfLife #UltimateReality #MeaningOfInformation #ComplexSystems #HistoryOfScience #Interdisciplinary #SciencePhilosophy #deepdive #skeptic #podcast #synopsis #books #bookreview #ai #artificialintelligence #booktube #aigenerated #history #alternativehistory #aideepdive #ancientmysteries #hiddenhistory #futurism #videoessay
