When the JWST captured the first images of the earliest galaxies in our universe, scientists were shocked.  The galaxies appeared to be way too bright, way too big, and way too mature to have formed so soon after the Big Bang. This discovery has, rightfully so, sparked a massive debate among astrophysicists. Some even started to question the standard model of cosmology.  However, using new simulations, some astrophysicists decided to investigate this controversy. Among these extraordinarily talented and bright minds is today’s guest, Chris Hayward, founding member of the FIRE project.  Tune in to discover the truth about the mysterious brightness at cosmic dawn!
