The James Webb Space Telescope (JWST) has revealed galaxies that seem too massive, too early— discoveries that could shake the very foundations of cosmology. Theoretical astrophysicist Priya Natarajan explores whether JWST’s findings truly “blow up” our current understanding of the universe. What surprises Priya most? What new questions do these discoveries raise about dark matter, dark energy, and the Big Bang itself? Discover how JWST challenges existing cosmological models, what the early universe looked like in unprecedented detail, and why new data might redefine cosmic history. Natarajan's book, Mapping the Heavens: The Radical Scientific Ideas That Reveal the Cosmos, is available for purchase now,
