JWST Confirms the Hubble Constant, But There’s a Catch

The universe is expanding, but how fast? And why does it matter? In this episode, we will talk about the Hubble constant, which is the rate of expansion of the universe, and the Hubble tension, which is the discrepancy between different methods of measuring it. We will also discuss the latest results from NASA’s James Webb Space Telescope, which confirm the accuracy of one of the methods, but also deepen the mystery of why it differs from another method.
