The study, <a href=\"https:\/\/link.aps.org\/doi\/10.1103\/vfny-pgc2\" target=\"_blank\">published<\/a> in the journal <i>Physical Review Research<\/i>, introduces a radical change in the understanding of the first moments after the Big Bang, without relying on the speculative assumptions that physicists have traditionally assumed.<\/p>\n<p>For decades, cosmologists have worked under the inflationary paradigm, a model that suggests that the universe expanded extremely rapidly, in a fraction of a second, thus paving the way for everything we observe today. But this model includes too many adjustable parameters\u2014the free parameters\u2014which can be modified. Scientifically, this poses a problem, as it makes it difficult to know whether a model is truly predicting or simply adapting to the data.<\/p>\n<p>In a significant breakthrough, the team has proposed a model in which the <a href=\"https:\/\/phys.org\/tags\/early+universe\/\" rel=\"tag\" class=\"\">early universe<\/a> does not require any of these arbitrary parameters. Instead, it begins with a well-established cosmic state called De Sitter space, which is consistent with current observations of dark energy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A team of scientists led by expert Ra\u00fal Jim\u00e9nez, ICREA researcher at the University of Barcelona\u2019s Institute of Cosmos Sciences (ICCUB), in collaboration with the University of Padua (Italy), has presented a revolutionary theory about the origins of the universe.
