The idea is that gravity in a volume of space can be described by information encoded on that volume's boundary, as in the AdS/CFT correspondence, suggesting three-dimensional reality may emerge from lower-dimensional information. Commenters on the post are debating what this implies about the fundamental nature of space, time and whether reality is a projection.","why":"A new Quanta Magazine explainer on the holographic nature of gravity sparked discussion among Hacker News readers.","tone":"neutral","entities":["Quanta Magazine","Hacker News","holographic principle","AdS/CFT correspondence"],"summarized_at":"2026-09-26T16:50:15.176090Z","meta":{"via":"scan","lang":"en","link":"https://www.quantamagazine.org/gravity-seems-holographic-what-does-that-mean-for-reality-20260925/","term":"hbo","hn_id":"49845998","comments":216},"nw":0.15,"promo":0.02,"kind":"opinion_debate","importance":1.58,"hidden":false,"hide_reason":null,"judged_at":"2026-09-26T17:51:16.892814Z","title_en":null,"section_name":"Science","category_name":"Physics","timeline":[{"captured_at":"2026-09-26T16:31:27.675667Z","rank":8,"volume":253},{"captured_at":"2026-09-26T16:34:06.864688Z","rank":8,"volume":253},{"captured_at":"2026-09-26T16:35:58.945546Z","rank":8,"volume":253},{"captured_at":"2026-09-26T16:42:04.911549Z","rank":7,"volume":256},{"captured_at":"2026-09-26T16:54:55.223494Z","rank":7,"volume":258},{"captured_at":"2026-09-26T17:03:34.613956Z","rank":7,"volume":258},{"captured_at":"2026-09-26T17:05:47.236080Z","rank":7,"volume":258},{"captured_at":"2026-09-26T17:10:40.080839Z","rank":7,"volume":258},{"captured_at":"2026-09-26T17:25:40.018461Z","rank":7,"volume":260},{"captured_at":"2026-09-26T17:28:25.771893Z","rank":6,"volume":261},{"captured_at":"2026-09-26T17:29:54.175299Z","rank":6,"volume":261},{"captured_at":"2026-09-26T17:33:54.374519Z","rank":1,"volume":262},{"captured_at":"2026-09-26T17:44:09.491224Z","rank":6,"volume":262},{"captured_at":"2026-09-26T17:59:40.340638Z","rank":4,"volume":263},{"captured_at":"2026-09-26T18:04:39.740175Z","rank":6,"volume":263},{"captured_at":"2026-09-26T18:05:17.527810Z","rank":6,"volume":263},{"captured_at":"2026-09-26T18:07:04.255285Z","rank":7,"volume":263},{"captured_at":"2026-09-26T18:13:20.209539Z","rank":7,"volume":263},{"captured_at":"2026-09-26T18:16:37.660849Z","rank":7,"volume":263},{"captured_at":"2026-09-26T18:26:45.548521Z","rank":7,"volume":263},{"captured_at":"2026-09-26T18:28:22.436170Z","rank":6,"volume":267},{"captured_at":"2026-09-26T18:51:22.654429Z","rank":1,"volume":268},{"captured_at":"2026-09-26T19:17:03.886767Z","rank":4,"volume":268},{"captured_at":"2026-09-26T20:09:48.539381Z","rank":1,"volume":269},{"captured_at":"2026-09-26T20:36:48.507012Z","rank":4,"volume":273},{"captured_at":"2026-09-26T21:31:34.729783Z","rank":1,"volume":275},{"captured_at":"2026-09-26T21:58:35.335689Z","rank":4,"volume":275}],"posts":[{"platform":"hn","url":"https://news.ycombinator.com/item?id=49845998","author":"ibobev","title":"Gravity seems holographic.
