But researchers believe that it could be the result of colliding pieces of <a href=\"https:\/\/www.independent.co.uk\/topic\/dark-matter\" rel=\"nofollow noopener\" target=\"_blank\">dark matter<\/a>, or the spinning of neutron stars.<\/p>\n<p>If the explanation is the former, and the glow comes from <a href=\"https:\/\/www.independent.co.uk\/topic\/dark-matter\" rel=\"nofollow noopener\" target=\"_blank\">dark matter<\/a>, it might be the first ever proof that it actually exists.<\/p>\n<p>\u201cDark matter dominates the universe and holds galaxies together. It\u2019s extremely consequential and we\u2019re desperately thinking all the time of ideas as to how we could detect it,\u201d said co-author <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/physics-astronomy.jhu.edu\/directory\/joseph-silk\/\">Joseph Silk<\/a>, a professor of physics and astronomy at Johns Hopkins, in a statement.<\/p>\n<p>\u201cGamma rays, and specifically the excess light we\u2019re observing at the centre of our <a href=\"https:\/\/www.independent.co.uk\/topic\/galaxy\" rel=\"nofollow noopener\" target=\"_blank\">galaxy<\/a>, could be our first clue.\u201d<\/p>\n<p>In a new study, scientists made a map of where they expected dark matter to be found in the <a href=\"https:\/\/www.independent.co.uk\/topic\/milky-way\" rel=\"nofollow noopener\" target=\"_blank\">Milky Way<\/a>. In its early years, smaller systems of dark matter and other material came into the galaxy towards its centred and clustered together, increasing the number of collisions between dark matter.<\/p>\n<p>Those maps are part of a set of evidence that suggests that the glow of gamma rays at the middle of the Milky Way are coming from dark matter. The simulations show the same signal and characteristics as those found in the real world, they say.<\/p>\n<p>But they note that old neutron stars that are woken back up could also be emitting light that would also explain many of the same pieces of evidence. But, for that theory to work, scientists have to change the maths slightly to suggest there are more of those pulsars in existence than they actually see.<\/p>\n<p>Researchers hope that another experiment will finally provide more certainty \u2013 and could give the first proof of dark matter. If the gamma rays have higher energy, they are probably those stars, while lower energy rays probably come from collisions between dark matter.<\/p>\n<p>\u201cA clean signal would be a smoking gun, in my opinion,\u201d Silk said. <\/p>\n<p>Until then, they hope to do similar simulations of other galaxies around the Milky Way, and then compare that to the data.<\/p>\n<p>\u201cIt\u2019s possible we will see the new data and confirm one theory over the other,\u201d Silk said. \u201cOr maybe we\u2019ll find nothing, in which case it\u2019ll be an even greater mystery to resolve.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Your support helps us to tell the story From reproductive rights to climate change to Big Tech, The&hellip;\n","protected":false},"author":2,"featured_media":205930,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[90,416,56,54,55],"class_list":{"0":"post-205929","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-science","9":"tag-space","10":"tag-uk","11":"tag-united-kingdom","12":"tag-unitedkingdom"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/205929","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=205929"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/205929\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/205930"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=205929"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=205929"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=205929"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
