Simulations Suggest Rocky Planets Could Form 100 Million Years After Big Bang

New computer simulations indicate that rocky planets may have begun forming only 100 million years after the Big Bang. The study attributes this early formation to massive supernovae that dispersed planet‑building elements throughout the early universe. Researchers modeled a young star system and found sufficient solid material and water to support the creation of Earth‑like worlds. The results challenge the long‑standing view that planet formation required a much later epoch. If confirmed, the finding would shift the timeline for the earliest possible rocky planets and alter theories of how planetary systems evolve.
