The James Webb Space Telescope sees too many mature galaxies in the early Universe—as if the orchestra played the finale before the conductor appeared. The solution: a microscopic 'hump' in the spectrum of primordial ripples: nature played one note slightly louder, and giant galaxies were born ahead of schedule. This is not just a patch for the theory, but the first clue linking quantum fluctuations from inflation to the birth of colossal stellar systems. Future sky surveys promise to turn the hypothesis into a new reality.
🎯 The term 'Population IV stars' was coined by the authors for primordial giants in massive halos—in contrast to classical Population III stars, born in mini-halos. These short-lived beacons could have seeded the cosmos with metals, shaping the chemical face of the entire universe.
