Vopson at the University of Portsmouth<\/a> offers a novel derivation of Newton\u2019s law of gravitation from the principles of information theory. Rather than treating gravity as a built-in feature of the universe, Vopson reframes it as a byproduct of information entropy minimization \u2014 a kind of cosmic data compression routine. The underlying claim is that gravity is not a law to be followed, necessarily, but more like a behavior to be expected in a universe functioning like a vast computer and, because nature is quantum, more like a vast quantum computer.<\/p>\n<p>\u201cMy findings in this study fit with the thought that the universe might work like a giant computer, or our reality is a simulated construct,\u201d Vopson said in <a href=\"https:\/\/www.port.ac.uk\/news-events-and-blogs\/news\/scientist-suggests-gravity-further-supports-theory-we-are-living-in-a-simulated-universe\" target=\"_blank\" rel=\"noopener\">a university news article<\/a>. \u201cJust like computers try to save space and run more efficiently, the universe might be doing the same. It\u2019s a new way to think about gravity \u2014 not just as a pull, but as something that happens when the universe is trying to stay organised.\u201d<\/p>\n<p><a href=\"https:\/\/thequantuminsider.com\/data\/\" onclick=\"_gs(&#039;event&#039;, &#039;DATA IN CONTENT NEW&#039;)\" class=\"responsive-image\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"data:image\/svg+xml,%3Csvg%20xmlns=\" http:=\"\" alt=\"Responsive Image\" data-lazy-src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/04\/Banners_Quantum-800-x-80-px-Option-1b.gif\"\/><\/a><\/p>\n<p><strong>The Second Law of Infodynamics<\/strong><\/p>\n<p>At the heart of the paper is the \u201c<a href=\"https:\/\/pubs.aip.org\/aip\/adv\/article\/13\/10\/105308\/2915332\/The-second-law-of-infodynamics-and-its\" target=\"_blank\" rel=\"noopener\">second law of infodynamics<\/a>,\u201d a theory Vopson previously developed to describe how information evolves in isolated systems. Unlike the second law of thermodynamics \u2014 which dictates that physical systems tend toward increasing disorder \u2014 the second law of infodynamics suggests that the entropy of informational systems decreases over time, evolving toward order and efficiency. In effect, nature trims the digital fat.<\/p>\n<p>This principle forms the basis for a radical reinterpretation of gravity. Instead of being a standalone interaction, gravity emerges as the entropic pull of matter seeking to simplify what could be described as its informational footprint in space. And if the rules of information compression and minimization apply universally, they might not just govern gravity \u2014 they could point to a deeper computational substrate underlying all of physics.<\/p>\n<p>While not directly addressed in the study, for researchers in quantum information science, this idea resonates with a broader shift toward seeing nature as inherently computational. Quantum computers operate on the premise of information encoded in qubits, evolving under precise constraints to reduce uncertainty. If spacetime behaves similarly, then gravity could be a visible sign of a hidden quantum algorithm at work.<\/p>\n<p><strong>Reimagining Space as a Discrete Information Grid<\/strong><\/p>\n<p>To ground the theory, Vopson builds a simplified two-dimensional model of space, divided into a 10-by-10 grid of elementary cells \u2014 analogous to pixels on a screen or registers in a quantum computer. Each cell can store a single bit of information, either empty (\u201c0\u201d) or occupied by matter (\u201c1\u201d). The initial entropy of the system is zero when all cells are unoccupied.<\/p>\n<p>For gamers and game designers out there, this may sound familiar.<\/p>\n<p>\u201cThe process is identical to how a digital computer game, virtual reality application, or other advanced simulation would be designed,\u201d Vopson said.<\/p>\n<p>The thought experiment introduces four point masses randomly placed on the grid. This increases the information entropy, since the distribution becomes less predictable. But if these particles move toward a central location and merge \u2014 forming a single, more massive object \u2014 the overall entropy drops. This self-organization, according to Vopson, is not due to an external force acting at a distance, but a natural drive to compress information.<\/p>\n<p>This kind of optimization mirrors what happens in quantum computation. When running a quantum algorithm, a system of qubits evolves to reduce uncertainty and reach a low-energy, high-efficiency solution. Vopson suggests that gravity may arise from a similar informational evolution, an entropic force emerging from the universe\u2019s attempt to store and process information with maximum efficiency.<\/p>\n<p><strong>A New Path to Newton\u2019s Law<\/strong><\/p>\n<p>The study goes a step further by using this framework to derive Newton\u2019s gravitational formula. Vopson calculates the entropic force required to shift particles toward lower entropy states, applying principles from Shannon\u2019s information theory, thermodynamics, and the mass\u2013energy\u2013information (M\/E\/I) equivalence principle, a relationship he introduced in 2019 that links an object\u2019s mass to the energy and information it carries.<\/p>\n<p>By treating each unit of space as capable of storing a bit, and calculating how entropy changes as a particle shifts positions, the paper shows that the resulting entropic force scales precisely with mass and distance in a way that reproduces Newton\u2019s inverse-square law of gravity. In this model, gravitational attraction is not a cause, but an outcome, a statistical behavior of a system rearranging itself to achieve computational efficiency.<\/p>\n<p>The method draws heavily from information theory but doesn\u2019t discard established physics. It accepts that objects appear to attract each other in line with classical laws but interprets this attraction as a byproduct of deeper information processing rules. In doing so, it offers a bridge between macroscopic forces and microscopic logic, potentially tying gravity to the same principles that drive quantum computation.<\/p>\n<p><strong>How It Compares to Verlinde\u2019s Entropic Gravity<\/strong><\/p>\n<p>Vopson\u2019s theory builds on \u2014 but significantly diverges from \u2014 an earlier entropic gravity hypothesis put forth by Dutch physicist Erik Verlinde in 2011. Verlinde argued that gravity results from changes in entropy on a holographic screen surrounding a mass, borrowing from the holographic principle and black hole thermodynamics. In that model, entropy increases as objects move apart, and gravity emerges as a restoring force.<\/p>\n<p>But there is a difference: Vopson\u2019s model is grounded in entropy reduction. Rather than deriving gravity from a hypothetical screen, it uses a discretized version of space and assumes the laws of information drive the rearrangement of mass. It avoids invoking emergent spacetime or extra dimensions, focusing instead on the drive toward simpler, more compressible configurations. It\u2019s a notion with parallels in quantum error correction, where redundant information is minimized to preserve coherence.<\/p>\n<p>Both approaches end up at Newton\u2019s law, but they differ in direction and foundations. Verlinde\u2019s model ties gravity to statistical mechanics and entropy increase. Vopson links it to computational optimization and entropy decrease. The result, he argues, is a more concrete mechanism for understanding why matter clumps together and why the universe appears to self-organize at all scales\u2014from atoms to galaxies.<\/p>\n<p><strong>Implications for Quantum Computing and Fundamental Physics<\/strong><\/p>\n<p>For quantum scientists, the idea that gravity is an informational effect opens up speculative but potentially interesting avenues to explore. If gravitational behavior is just the outcome of an information system optimizing itself, then simulating gravity might be possible on quantum devices. That could happen, perhaps not by recreating spacetime geometry, but by mimicking how information entropy evolves.<\/p>\n<p>This raises another speculative question: could a sufficiently large quantum computer replicate gravity by running the right algorithm? Could we model cosmological processes, galaxy formation, or even black hole dynamics as computational optimizations?<\/p>\n<p>Taking, in the words of <a href=\"https:\/\/www.youtube.com\/watch?v=4xgx4k83zzc\" target=\"_blank\" rel=\"noopener\">Spinal Tap guitarist  one more speculative push over the cliff<\/a>, if the universe itself is behaving like a quantum computational system, then quantum information \u2014 not mass or energy \u2014 might be the most fundamental currency of nature. The framework also offers new perspectives on dark matter and dark energy, which might be manifestations of information imbalances or inefficiencies in the universe\u2019s compression routines.<\/p>\n<p>And for those entertaining the \u201csimulation hypothesis,\u201d Vopson\u2019s work offers another data point. A universe where gravity is an emergent data-processing artifact would be more consistent with simulation logic than with traditional field theories. While the study avoids philosophical speculation, its assumptions and results naturally lend themselves to questions about the nature of reality and whether the universe is, at root, a computation.<\/p>\n<p><strong>Limitations and the Road Ahead<\/strong><\/p>\n<p>Despite its elegant logic and mathematical coherence, the study remains theoretical. It lacks direct experimental validation and operates within a simplified 2D model. Future work would need to extend this to 3D, incorporate general relativity, and test whether the entropic behavior holds under complex quantum interactions or in real physical systems.<\/p>\n<p>There are also conceptual questions about how this information-based force would interact with quantum fields, curved spacetime, or relativistic phenomena. And although the theory aligns with Newtonian gravity, it has yet to demonstrate compatibility with Einstein\u2019s equations, gravitational lensing, or black hole behavior beyond entropy accounting.<\/p>\n<p>That being said, Vopson\u2019s model challenges physicists to consider whether information, not matter, is the foundation of everything \u2014 and whether gravity is merely the universe\u2019s way of thinking more efficiently.<\/p>\n<p>Ultimately, whether or not this hypothesis holds up under future scrutiny, it highlights the growing convergence between physics and information science. In a world increasingly shaped by quantum computation, the laws of nature may not just resemble code \u2014 they might be code. And gravity, long considered one of the deepest mysteries of physics, might just be a side effect of the universe keeping its files tidy. <\/p>\n<p>And, for anyone who has taken a glimpse of my computer desktop or counted the number of tabs I have open, we should be all relieved I\u2019m not in charge of the universe\u2019s file organization.<\/p>\n","protected":false},"excerpt":{"rendered":"Insider Brief A new study published in AIP Advances suggests gravity may emerge from entropy reduction in a&hellip;\n","protected":false},"author":2,"featured_media":63202,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3845],"tags":[19804,32594,74,70,464,16,15,6684],"class_list":{"0":"post-63201","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-physics","8":"tag-gravity","9":"tag-optimization","10":"tag-physics","11":"tag-science","12":"tag-simulation","13":"tag-uk","14":"tag-united-kingdom","15":"tag-universe"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114427523507932940","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/63201","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=63201"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/63201\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/63202"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=63201"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=63201"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=63201"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
