Has the Standard Model of Cosmology Been Broken by the James Webb Space Telescope? #SpaceSaturday
The James Webb Space Telescope has provided the world with astonishing new images of the cosmos. It has also looked deeper into space than any other telescope, which means it has looked deeper into the past than any other telescope. What we have found in these unimaginably early moments in time is evidence that the Standard Model of cosmology, while still a robust way of looking at the cosmos, may need some adjustment. Here’s more from Wired:
Astronomers began asking whether the profusion of early big things defies the current understanding of the cosmos. Some researchers and media outlets claimed that the telescope’s observations were breaking the standard model of cosmology—a well-tested set of equations called the lambda cold dark matter, or ΛCDM, model—thrillingly pointing to new cosmic ingredients or governing laws. It has since become clear, however, that the ΛCDM model is resilient. Instead of forcing researchers to rewrite the rules of cosmology, the JWST findings have astronomers rethinking how galaxies are made, especially in the cosmic beginning. The telescope has not yet broken cosmology, but that doesn’t mean the case of the too-early galaxies will turn out to be anything but epochal.
