Extra Dimensions Could Change Everything We Know About Physics | Dan Hooper [Ep. 459]

Is the universe hiding extra dimensions we can’t see? Could a graviton – a particle we haven’t even proven to exist – change everything we know about the cosmos? And what does the future of physics hold if the standard model fails? Today, I sit down with the renowned cosmologist Dan Hooper to discuss some of the most complex and exciting theories in modern cosmology. Dan is a leading theoretical physicist at Fermilab and a professor at the University of Chicago, specializing in the mysteries of dark matter, the early universe, and extra dimensions.  In this thrilling episode, Dan and I explore how hidden dimensions and mysterious particles could fundamentally challenge our understanding of the universe!  Tune in!
