The universe&#8217;s fundamental particles also formed. It was still so hot, though, that these particles hadn&#8217;t yet assembled into many of the subatomic particles we have today, such as the proton. As the universe kept expanding, this piping-hot primordial soup\u2014called the quark-gluon plasma\u2014continued to cool. Some\u00a0<a href=\"https:\/\/www.nationalgeographic.com\/science\/article\/higgs-boson-decay-quarks-lhc-standard-model-physics\">particle colliders, such as CERN&#8217;s Large Hadron Collider<\/a>, are powerful enough to re-create the quark-gluon plasma.<\/p>\n<p>Radiation in the early universe was so intense that colliding photons could form pairs of particles made of matter and antimatter, which is like regular matter in every way except with the opposite electrical charge. It&#8217;s thought that the early universe contained equal amounts of matter and antimatter. But as the universe cooled, photons no longer packed enough punch to make matter-antimatter pairs. So like an extreme game of musical chairs, many particles of matter and antimatter paired off and annihilated one another.<\/p>\n<p>Somehow, some excess matter survived\u2014and it&#8217;s now the stuff that people, planets, and galaxies are made of. Our existence is a clear sign that the laws of nature treat matter and antimatter slightly differently. Researchers have experimentally observed\u00a0this rule imbalance, called CP violation, in action. Physicists are still trying to figure out exactly how matter won out in the early universe.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Building_Atoms\"><\/span><b>Building Atoms<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The\u00a0Big Bang\u00a0theory is the exceptional cosmological model\u00a0explaining the existence of the\u00a0observable universe\u00a0from the\u00a0earliest known periods through its subsequent large-scale evolution.<sup id=\"cite_ref-3\" class=\"reference\"><\/sup> The model states how the universe expanded\u00a0from an initial state of high\u00a0density\u00a0and\u00a0temperature, <sup id=\"cite_ref-HTUW_4-0\" class=\"reference\"><\/sup>and provides a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the\u00a0cosmic microwave background\u00a0(CMB)\u00a0radiation, and\u00a0large-scale structure.
