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\u2019m diving into that study, looking at what model they used to get at that claim (a combination of the expansion of the universe and \u201ctired light\u201d ideas of redshift), how this impacts our best model of the Universe and the so-called \u201cCrisis is Cosmology\u201d, and why I\u2019m not convinced yet!<\/p>\n<p>#astronomy #JWST #cosmology.<\/p>\n<p>My previous YouTube video on how JWST\u2019s massive galaxies are no longer \u201cimpossible\u201d \u2014 <a href=\"https:\/\/youtu.be\/W4KH1Jw6HBI\">https:\/\/youtu.be\/W4KH1Jw6HBI<\/a><\/p>\n<p>Gupta et al.
