In this episode of The Space Between, we dive headfirst into one of the hottest debates in modern cosmology: the true age of the universe and what new data from the James Webb Space Telescope (JWST) means for our understanding of cosmic expansion. Headlines are screaming “crisis” and claiming the universe is expanding at two different speeds—so what’s fact, what’s speculation, and what’s just sensational storytelling?

We explore the “Hubble Tension,” the discrepancy between early-universe and late-universe measurements of cosmic expansion, and why JWST’s confirmation of Hubble’s data is such a big deal. At the same time, we break down how the science gets spun in the media—why articles about “two universes” or “multiple speeds” of expansion may capture clicks, but miss the nuance of what astronomers are actually saying.

Expect a blend of astrophysics, philosophy, and some critical media literacy as we ask: how should we talk about cosmic uncertainty without losing public trust in science?
