After 2 years in space, the James Webb telescope has broken cosmology. Can it be fixed?Feature For decades, measurements of the universe's expansion have suggested a disparity known as the Hubble tension, which threatens to break cosmology as we know it. Now, on the eve of its second anniversary, a new finding by the James Webb Space Telescope has only entrenched the mystery.
