Enormous 'Fossilized' Bubble Suggests Big Bang Relic
A massive structure named Ho'oleilana, consisting of galaxies clustered around a gigantic spherical void, has been discovered just 820 million light-years from the Milky Way. Researchers believe it could be a relic from the Big Bang, specifically a baryon acoustic oscillation frozen in time and stretched out by the universe's expansion. The size of the bubble suggests that the universe may be expanding more rapidly than previously thought. Further observations will be conducted to confirm this hypothesis.
