From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it’s investigating the financials of Elon Musk’s pro-Trump PAC or producing our latest documentary, ‘The A Word’, which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.<\/p>\n
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.<\/p>\n
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.<\/p>\n

Scientists<\/a> might have found a way to finally spot dark matter<\/a>.<\/p>\n Dark matter makes up most of the universe and is integral to the solar systems and galaxies<\/a> that surround us. But it is invisible, and scientists can only understand it by studying the way that it interacts with the matter we can actually see.<\/p>\n Now researchers believe that they might be able to see it through the traces that it leaves on the gravitational waves that are constantly travelling through space and which we can detect on Earth.<\/p>\n Astronomers<\/a> have predicted how gravitational waves would look if they have come out of a black hole<\/a> that moved through dark matter, instead of empty space. They then applied that model to real data from gravitational wave signals that have already been detected.<\/p>\n From the 27 clearest signals of gravitational waves, 27 of them appeared to have emerged in a vacuum. But one of them, known as GW190728, seems to have the imprint of dark matter in its signal.<\/p>\n Researchers stress that the technique does not allow them to detect dark matter in itself. But it could offer a way of spotting the traces of it, which could then be used to examine possible traces of it using other techniques.<\/p>\n \u201cWe know that dark matter is around us. It just has to be dense enough for us to see its effects,\u201d said Josu Aurrekoetxea, from the MIT Department of Physics. \u201cBlack holes provide a mechanism to enhance this density, which we can now search for by analyzing the gravitational waves emitted when they merge.\u201d<\/p>\n The work is reported in a new paper, \u2018Scalar fields around black hole binaries in LIGO-Virgo-KAGRA\u2019, published in the journal Physical Review Letters.<\/p>\n","protected":false},"excerpt":{"rendered":"Your support helps us to tell the story From reproductive rights to climate change to Big Tech, The…\n","protected":false},"author":2,"featured_media":582619,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[90,416,56,54,55],"class_list":["post-582618","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-science","tag-space","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/582618","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=582618"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/582618\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/582619"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=582618"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=582618"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=582618"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
