"Unveiling the Enigmatic Giant Bubble: A Potential Big Bang Remnant in Our Galaxy"

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. It is believed to be a baryon acoustic oscillation, a frozen pressure wave from the beginning of the cosmos. 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.
