Since its deployment in deep space, the James Webb Space Telescope (JWST) has transformed our understanding of the early universe in ways that theorists never anticipated. Equipped with infrared sensors capable of peering through cosmic dust clouds, JWST has detected massive, luminous galaxies that formed just a few hundred million years after the Big Bang. According to classical cosmological models, the universe at that epoch should have contained only small, fragmented clusters of primitive stars. The presence of mature, highly organised galactic structures so early in cosmic history suggests that stars and supermassive black holes must have grown at an astonishingly accelerated pace. While some astrophysicists suggest that our estimates of early star formation rates require substantial revision, others propose that alternative physics may be needed to account for these massive primordial giants. Whatever the ultimate explanation proves to be, JWST has undeniably opened a revolutionary new window onto our cosmic origins. According to classical cosmological models described in the passage, what did astronomers expect the early universe to look like?
- A)It was expected to contain fully mature galaxies with massive supermassive black holes at their cores.
- B)It should have consisted solely of small, fragmented clusters of primitive stars.
- C)It was believed to be completely devoid of any stars or hydrogen gas for billions of years.
- D)It was presumed to be filled with impenetrable clouds of cosmic dust that blocked all light.
- E)It was expected to expand at a decelerating rate due to gravitational pull.
