This Wild New Idea Might Explain the Entire Universe in One Shot"},"content":{"rendered":"

A recent study proposes that gravity<\/strong>, the force shaping galaxies and anchoring planets, might not be fundamental after all. Instead, it could arise from entropy<\/strong>, a measure of disorder. The theory, developed by physicist and mathematician Ginestra Bianconi of Queen Mary University of London, aims to reconcile two long-conflicting pillars of physics: general relativity<\/strong> and quantum mechanics<\/strong>. By suggesting that quantum entropy might govern gravitational behavior, Bianconi\u2018s work introduces a new lens through which to view the universe\u2019s architecture.<\/p>\n

A Quantum Twist On Spacetime<\/p>\n

At the core of Ginestra Bianconi<\/a>\u2019s idea is something called quantum relative entropy, which is used to tell one quantum state from another. In this framework, spacetime itself behaves like a quantum operator, something that actively acts on quantum states and reshapes them. That is a big shift from Einstein<\/a>\u2019s picture, where gravity emerges from the way mass bends spacetime.<\/p>\n

When quantum entropy is woven into spacetime\u2019<\/a>s geometry, the model still allows for a gently curved, low-energy universe, just like the one we observe, but it changes the underlying explanation for gravity. In her recent paper published in published study in Physical Review D<\/a>, Bianconi put it simply:<\/p>\n

\n

\u201cGravity is derived from an entropic action coupling matter fields with geometry [of spacetime].\u201d<\/p>\n<\/blockquote>\n

The theory also introduces a so-called G-field, a vector field with both direction and strength, which helps connect matter and spacetime. <\/p>\n

Why Gravity Won\u2019t Go Quantum<\/p>\n

For decades, physicists have tried, and failed, to fully merge general relativity, which works beautifully on cosmic scales, with quantum mechanics, which rules the microscopic world. The two theories<\/strong> are built on very different assumptions, and that mismatch has made unification incredibly hard.<\/p>\n

Bianconi\u2019s approach tries to close that gap by treating gravity as something that emerges from the collective behavior of quantum states. According to a public research<\/a> <\/strong>from Queen Mary University of Londonby, this setup allows quantum wave functions to interact with the G-field, potentially easing the tension between quantum physics and relativity.<\/p>\n

In this picture, spacetime is no longer a passive backdrop. Instead, it becomes dynamic and responsive, shifting as quantum information changes. <\/p>\n

Gravity As A Clue To Dark Matter<\/p>\n

One of the most intriguing implications of the theory is its potential to explain the nature of dark matter<\/a><\/strong>. According to Bianconi, if gravity can be described in terms of particles<\/strong>, a possibility suggested by her entropic approach, then the G-field<\/strong> might account for dark matter\u2019s unseen influence.<\/p>\n

The Popular Mechanics report<\/a> noted that this could offer a new perspective on why dark matter has remained so elusive: it might not be made of exotic, undiscovered particles, but instead be a manifestation of gravitational fields shaped by quantum information. <\/p>\n

\n

\u201cThis work proposes that quantum gravity has an entropic origin and suggests that the G-field might be a candidate for dark matter,\u201d Bianconi explained. \u201cAdditionally, the emergent cosmological constant predicted by our model could help resolve the discrepancy between theoretical predictions and experimental observations of the universe\u2019s expansion.\u201d<\/p>\n<\/blockquote>\n

The theory is far from confirmed<\/strong>, yet it dares to rethink one of astrophysics\u2019 most elusive questions.<\/p>\n","protected":false},"excerpt":{"rendered":"A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after…\n","protected":false},"author":2,"featured_media":296274,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[271],"tags":[18,19,17,452,133],"class_list":{"0":"post-296273","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-physics","8":"tag-eire","9":"tag-ie","10":"tag-ireland","11":"tag-physics","12":"tag-science"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/115934677267993417","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/296273","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=296273"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/296273\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/296274"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=296273"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=296273"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=296273"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
