As the universe expands, the density of both regular and dark matter drops, while more and more dark energy manifests. To study the ultimate long-term fate of the universe, the researchers ignored matter and focused solely on the evolution of holographic dark energy.<\/p>\n<p>They found that, as expected, holographic dark energy will continue to expand the universe. But, over time, its influence will slowly peter out and slow acceleration. The universe&#8217;s expansion rate will steadily decrease until the cosmos reaches a nearly static value, essentially locking it to a final size.<\/p>\n<p>But as the universe&#8217;s expansion slows down, the density of holographic dark energy dwindles along with it. And since the density of matter also shrinks as the universe expands, the universe grinds to a halt. The researchers dub this scenario &#8220;the long freeze,&#8221; in contrast to other commonly known fates of the universe like the &#8220;Big Freeze&#8221; (the accelerated expansion continues unabated) and the &#8220;Big Crunch&#8221; (something causes the universe to contract back toward the <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.livescience.com\/65700-big-bang-theory.html\" data-before-rewrite-localise=\"https:\/\/www.livescience.com\/65700-big-bang-theory.html\"><u>Big Bang<\/u><\/a>).<\/p>\n<p>The long freeze isn&#8217;t a rosy scenario. While the universe&#8217;s expansion will eventually stop, there won\u2019t be any new sources of energy for all the matter inside of it. This means that eventually all the stars will wink out and decay, and all the subatomic particles will drift away from each other in the cold.<\/p>\n<p>Unfortunately, even in their most exotic theories, cosmologists can&#8217;t come up with a way to give the universe a happy ending.<\/p>\n<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.livescience.com\/physics-mathematics\/dark-energy\/the-universe-may-end-in-a-big-freeze-holographic-model-of-the-universe-suggests\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have found that a hypothetical form of dark energy may lead to a grim fate for the universe: a &#8220;long freeze&#8221; where everything just\u2026slows down.
