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! Key Takeaways: 00:00 Intro  01:12
