What happens when science meets nothingness? In this episode, we explore cosmic voids—vast regions of near-empty space like the KBC Void, where the Milky Way itself resides. Could these immense structures help solve the Hubble tension, the puzzling mismatch in our measurements of the universe’s expansion? We dive into galaxy flows, modified gravity theories like MOND, and the challenges they pose to the standard $\Lambda$CDM model. But the journey doesn’t stop with physics: we also examine the philosophical Void, from Greek thinkers to Buddhism and Taoism, exploring how cultures have wrestled with the meaning of emptiness. Science, cosmology, and philosophy collide in the mysteries of the Void.
