As [*The Guardian* reports](), the luminaries of cosmology will be [re-examining some basic assumptions]() about the universe — right down to the over-a-century-old theory that it's expanding at a constant rate. "We are, in cosmology, using a model that was first formulated in 1922," coorganizer and Oxford cosmologist Subir Sarkar told the newspaper, in an apparent reference to the year Russian astronomer Alexander Friedmann outlined the possibility of cosmic expansion based on Einstein's general theory of relativity. "We have great data, but the theoretical basis is past its sell-by date," he added. "More and more people are saying the same thing and these are respected astronomers." ## Reality Check A number of researchers have found evidence that the universe may be [expanding more quickly in some areas]() compared to others, raising the tantalizing possibility that megastructures could be influencing the universe's growth in significant ways. Sarkar and his colleagues, for instance, are suggesting that [the universe is "lopsided]()" after studying over a million quasars, which are the active nuclei of galaxies where gas and dust are being gobbled up by a supermassive black hole. The team found that one hemisphere actually hosted slightly more of these quasars, suggesting one area of the night sky was more massive than the other, undermining our conception of [dark energy](), a hypothetical form of energy used to explain why the universe is expanding at an accelerated rate. "It would mean that two-thirds of the universe has just disappeared," Sarkar told *The Guardian*. Other researchers have suggested that the cosmological constant, which has been used for decades as a way to denote the rate of the universe's expansion, actually varies across space, which would contradict the standard model of physics. In short, astronomers are more than ready to reevaluate the century-old footsteps they've been following to gain a better understanding of the universe around us. "I find that frankly annoying that this principle hasn’t been checked," Sarkar told the British newspaper. "We need more exploration on where, if at all, the standard model breaks down," Canadian-American astronomer and Carnegie Observatories director Wendy Freedman added. "I don’t think there is an obvious thing that is going to stand the test of time." **More on the cosmological constant:** *[New Paper Claims Dark Matter Doesn't Exist at All]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
