It\u2019s the familiar force that keeps our feet on the ground and Earth\u2019s atmosphere from hurtling into space. On grander scales, it has shaped the evolution of the universe. What a shame, then, that it sometimes lets you down. To square the whirligig rotations of galaxies and galaxy clusters with our picture of gravity, we have to invent a whole new form of matter that no one has ever seen: dark matter. To explain why the universe\u2019s expansion is accelerating, we have to conjure up an equally mysterious essence known as dark energy.<\/p>\n<p>But what if we never really knew gravity at all? What if out there, beyond where we can easily keep our eye on it, the universal force doesn\u2019t stick to the rules?<\/p>\n<p>It\u2019s a heretical idea, if not an entirely novel one. Now though, renewed scrutiny of galaxies and surprises from the realm of quantum information theory are reinvigorating the quest to rethink gravity. Radical ideas are emerging that amount to a fundamental transformation of how we understand space-time \u2013 and what gravity really is. In this picture, dark matter ceases to exist. And dark energy, rather than being something that works against gravity, might be part of what creates it.<\/p>\n<p>[ <a href=\"https:\/\/www.newscientist.com\/article\/mg23331170-200-rules-of-attraction-why-its-time-to-rethink-how-gravity-works\/\" target=\"_blank\">click to continue reading at New Scientist<\/a> ]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>from New Scientist Rules of attraction: Why it\u2019s time to rethink how gravity works Fresh suspicions have reopened the case against dark matter, forcing a fundamental rethink of the familiar force that keeps our feet on the ground By\u00a0Mark Anderson Julien Pacaud GRAVITY is supposed to be reliable.
