Скачать или смотреть James Webb Just Measured a Number That Should Not Be Changing

The expansion rate of the universe should be one number. It's not.

Two of the most precise measurements in the history of physics give two different answers. The ancient light from the Big Bang says 67. Exploding stars in the nearby universe say 73. The gap between them has hit five sigma - the same statistical threshold used to confirm the Higgs boson. Something is wrong, and nobody knows what.

So NASA pointed the most powerful telescope ever built directly at the problem. The James Webb Space Telescope didn't fix it. It made it worse.

This is the Hubble tension - a crack running through the foundation of modern cosmology. And it might be the first real evidence that our best model of the universe is missing something.

In this calming long-form space documentary, we trace the full story of the Hubble tension: from Edwin Hubble's first measurements in 1929, through decades of feuding astronomers, to the Planck satellite, the SH0ES collaboration, and Webb's landmark 2023 observations. We break down exactly how each method works, why both are so trustworthy, and why that trustworthiness is precisely what makes the disagreement so alarming.
