Can\u2019t-miss innovations from the bleeding edge of science and tech<\/p>\n
You\u2019d hope that the world\u2019s brightest scientific minds would more or less agree on the nature of our reality \u2014 but one of the largest physics surveys in history instead found that pretty much no one agrees on anything.\u00a0<\/p>\n
Published by the American Physical Society, the survey<\/a> queried over 1,600 experts from disciplines ranging from astrophysics to particle physics, along with a chunk of respondents who identified as \u201cscience enthusiasts.\u201d The results showed that there\u2019re still quite a few strikingly differing opinions on the standard model of cosmology, the scientific culmination of our understanding of our physical world which describes the origins of our universe and how it functions on a grand scale today.\u00a0<\/p>\n \u201cI think the most surprising finding was the gap between the public perception of scientific consensus and what scientists actually said when asked,\u201d coauthor of the survey Niayesh Afshordi at the University of Waterloo in Canada and the Perimeter Institute told Gizmodo<\/a>.\u00a0\u201cIdeas often presented as the standard view, such as inflation, string theory, particle dark matter, or a constant dark energy, did not command overwhelming support.\u201d<\/p>\n The closest thing to a consensus came from the question \u201cWhat is the Big Bang?\u201d to which 68 percent said it was a \u201chot dense state \u2014 which may or may not correspond to a beginning of time.\u201d But the flip side of that was revealing: just 20 percent answered that it was the \u201cabsolute beginning of time with a singularity at its start.\u201d<\/p>\n There was even more disagreement over dark matter<\/a>, a hypothetical substance that we can see the gravitational fingerprints of everywhere and which appears to make up 80 percent of the mass in the universe, but which we are yet to prove exists because it\u2019s invisible to all forms of direct detection. It\u2019s an essential part of the standard model, but it doesn\u2019t elucidate what dark matter is. Naturally, opinions differ, with only 10 percent holding the traditional view that it\u2019s made of massive particles called WIMPs, and 21 percent answering that it\u2019s a hybrid of some of the other popular ideas, like it being trapped in primordial black holes<\/a>.<\/p>\n Dark energy\u2019s responses reflect recent developments in the field. The traditional view of it as a cosmological \u201cconstant\u201d was just 24 percent, which was less than the view that dark energy changes over time, at 26 percent, after observations from a recent DESI survey indicated<\/a> that it may be weakening.<\/p>\n All told, it\u2019s a fascinating reflection on the tenuous nature of scientific insight and consensus. One of the most earth-shattering developments in physics, the uncertainty principle, is that there\u2019s a limit to what we can know about the smallest particles that underpin our reality.\u00a0 There\u2019s only so much we can confidently glean about the cosmos from our tiny outpost in space. <\/p>\n But disagreement isn\u2019t a bad thing. Science isn\u2019t about blind acceptance, but constantly testing ideas, even ones that seem beyond reproach, poking and prodding our assumptions about how the world works. When you\u2019re grasping with some of the most consequential questions in physics, of course you\u2019re going to get different answers, even if officially there\u2019s a \u201cstandard\u201d model.<\/p>\n
