The video explores the discovery of the Fermi and Erosita Bubbles in the Milky Way, which emit gamma rays and X-rays, respectively. These structures suggest a powerful event occurred less than 3 million years ago. Two main theories propose that the bubbles were formed by either a burst of star formation or an outburst from the supermassive black hole, Sagittarius A*. Scientists use simulations to study these phenomena, and future research may reveal more about our galaxy's dynamic nature.
