JWST | Is the Universe Twice as Old as we Think?

A new research study has come out claiming that to explain the massive galaxies found at huge distances in James Webb Space Telescope images, the Universe is older than we think, at 26.7 billion years (rather than 13.8 billion years old).

In this video I'm diving into that study, looking at what model they used to get at that claim (a combination of the expansion of the universe and "tired light" ideas of redshift), how this impacts our best model of the Universe and the so-called "Crisis is Cosmology", and why I'm not convinced yet!
