The area shown expanded between the first and final stages of the animation (upper left and right side respectively), increasing to ten million times its initial volume.  But still, it\u2019s many times smaller than the interior of a proton.  The enlarged cluster on the lower left is thought to have a mass of about 20 kg.

Physicists at the Universities of G\u00f6ttingen and Auckland have depicted this early period by significantly improving the capability of complex computer simulations.  Researchers have discovered that a complex network of structures can form in a trillionth of a second after the Big Bang.  The behavior of these objects resembles the distribution of galaxies in the present-day universe.  But unlike today, these primitive structures were microscopically small.  These typical aggregates, with only a few grams of mass, fit much smaller volumes than today\u2019s elementary particles.  Results of the study <em>Physical Review D<\/em> published in the bulletin.<\/p>\n<p>Researchers have observed the development of high-density regions that coexist with their own gravity.  \u201cThis physical space represented by our animation fits a million times on a single proton,\u201d says Professor Jens Niemeyer, head of the Astrophysics Cosmology Group at the University of G\u00f6ttingen.  \u201cThis is probably the biggest animation ever done on the smallest part of the universe.\u201d  The animations made make it possible to calculate more precisely the attributes of these remnants at the very beginning of the universe.<\/p>\n<p><em>University of G\u00f6ttingen.  \u00c7: O.<\/em><\/p>\n<div class=\"code-block code-block-7\">\n<div>\n\t\t\t<img decoding=\"async\" src=\"http:\/\/rezero-animeotaku.com\/wp-content\/uploads\/2021\/03\/There-are-177147-ways-to-tie-a-tie-3.png\" loading=\"lazy\"><\/div>\n<\/div>\n<p><strong><a href=\"https:\/\/blockads.fivefilters.org\/\">Let&#8217;s block ads!<\/a><\/strong> <a href=\"https:\/\/blockads.fivefilters.org\/acceptable.html\">(Why?)<\/a><\/p>\n<\/div>\n<hr>\n<p>\u30bd\u30fc\u30b9\u30b5\u30a4\u30c8\uff1a<a href=\"https:\/\/nichiani.net\/the-first-structures-in-the-universe-popular-science.html\">nichiani<\/a><\/p>\n<hr>\n<p>Source: \u30a2\u30cb\u30f2\u30bf\u03b2<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The results of the animation show the growth of small and extremely dense structures very soon after the expan &#8230; <a class=\"more\" href=\"https:\/\/nijilogu.com\/?p=206289\">\u7d9a\u304d\u3092\u8aad\u3080 &raquo;<\/a><\/p>\n","protected":false},"author":1,"featured_media":206290,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[1],"tags":[],"class_list":["post-206289","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-1"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/nijilogu.com\/wp-content\/uploads\/2021\/03\/There-are-177147-ways-to-tie-a-tie-3.png","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/nijilogu.com\/index.php?rest_route=\/wp\/v2\/posts\/206289","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nijilogu.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nijilogu.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nijilogu.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nijilogu.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=206289"}],"version-history":[{"count":0,"href":"https:\/\/nijilogu.com\/index.php?rest_route=\/wp\/v2\/posts\/206289\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nijilogu.com\/index.php?rest_route=\/wp\/v2\/media\/206290"}],"wp:attachment":[{"href":"https:\/\/nijilogu.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=206289"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nijilogu.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=206289"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nijilogu.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=206289"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
