A clear way to explore black holes and the expanding universe is the correlation between quantum fields that exist outside their horizons. These fields dissipate at the horizon and are thermally excited by Hawking radiation, which causes many paradoxes and technical difficulties. The existing unitary quantum mechanics cannot fully explain the quantum field dissipation and thermal excitation that occurs outside black holes and near the cosmological horizon. A new paradigm that has recently emerged proposes a quantum gravity theory in an open system called non-unitary quantum gravity theory to solve these problems, which can revolutionize the conceptual and technical understanding of black hole and cosmological horizon physics. Therefore, the study of quantum gravity theory in an open system will expand the understanding of quantum gravity in extreme conditions such as black holes and cosmology, and ultimately provide new insights into the nature of space-time.<\/p>\n\n\n\n<p><strong>Workshop Webpage<\/strong>: <a href=\"https:\/\/workshops.ift.uam-csic.es\/openquantumgravity\">here<\/a><\/p>\n\n\n\n<p><strong>Location<\/strong>: Instituto de F\u00edsica Te\u00f3rica<br><strong>When<\/strong>: 5-6 February\u00a0 2025<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/projects.ift.uam-csic.es\/severo\/wp-content\/uploads\/2025\/04\/DSC00012-1024x683.jpg\" alt=\"\" class=\"wp-image-2981\" srcset=\"https:\/\/projects.ift.uam-csic.es\/severo\/wp-content\/uploads\/2025\/04\/DSC00012-1024x683.jpg 1024w, https:\/\/projects.ift.uam-csic.es\/severo\/wp-content\/uploads\/2025\/04\/DSC00012-300x200.jpg 300w, https:\/\/projects.ift.uam-csic.es\/severo\/wp-content\/uploads\/2025\/04\/DSC00012-768x512.jpg 768w, https:\/\/projects.ift.uam-csic.es\/severo\/wp-content\/uploads\/2025\/04\/DSC00012-1536x1024.jpg 1536w, https:\/\/projects.ift.uam-csic.es\/severo\/wp-content\/uploads\/2025\/04\/DSC00012-930x620.jpg 930w, https:\/\/projects.ift.uam-csic.es\/severo\/wp-content\/uploads\/2025\/04\/DSC00012.jpg 1620w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\"><div style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\" class=\"taxonomy-category has-text-align-center has-link-color wp-elements-1f1b0f0e735d262df90dfd01bcdce4b8 wp-block-post-terms has-text-color has-nv-text-dark-bg-color has-background has-neve-link-color-background-color\"><a href=\"https:\/\/projects.ift.uam-csic.es\/severo\/index.php\/category\/workshop\/\" rel=\"tag\">Workshop<\/a><\/div><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Black holes and cosmology pose fundamental challenges to our understanding of physics, especially space-time physics.
