Summary

In this episode, we investigate the "Hubble Tension"—the most significant crisis in modern cosmology. At the center of the mystery is the Hubble Constant , the number that defines how fast the universe is stretching. While measuring the pulse of the cosmos sounds straightforward, our two primary methods have reached a violent stalemate, suggesting that our fundamental understanding of physics might be "broken."
