Impact of the James Webb Space Telescope on Cosmology
The James Webb Space Telescope (JWST) has significantly influenced the understanding of the early universe by revealing unexpected data that challenged existing cosmological theories. Initial findings related to the size and maturity of early galaxies sparked heated debates, asserting that the Big Bang may never have occurred. However, subsequent analyses and observations led researchers to reconcile these anomalies, largely confirming established theories while also suggesting revisions to some. This iterative process of questioning and reevaluating data exemplifies the scientific method, where anomalies lead to deeper exploration and understanding rather than outright rejection of prior knowledge.
