What if the Milky Way is drifting through a massive cosmic void - and that empty region is quietly distorting how we measure the Universe? In this video, we explore the KBC Void, also known as the Local Hole, the cosmic web, the Hubble tension, and why two trusted “rulers” of the expanding Universe give different answers. From galaxy flows and dark energy to the future disappearance of distant galaxies, this is the story of how empty space itself may be hiding one of cosmology’s biggest mysteries.
