Summary

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!

0:00.0	Is the universe lighting extra dimensions we can't see?
0:03.4	Could a graphiton, a particle we don't even know exists, change everything about the
0:08.1	Cosmos? And what does the future of physics hold if the standard model should happen to fail. I had the pleasure of exploring all these advanced concepts and more with the renowned cosmologist and physicist Dan Hooper in his former office at the University of Chicago. Now he's moved to the University of Wisconsin-Madison.
0:26.2	Go Badgers where I spent some time at the end of my graduate student career. In this thought-provoking conversation,
0:32.3	Dan and I challenge and explore how hidden dimensions and
0:36.4	mysterious particles can fundamentally challenge our understanding of the universe.
0:40.4	So let's dive deep into the fabric of the cosmic.
0:43.0	Any sufficiently advanced
0:48.0	any sufficiently advanced technology
0:51.0	is indistinguishable from magic.
0:55.6	Open the pod bay doors.
0:57.6	Welcome to a very special episode of the Into the Impossible
1:01.6	podcast with a colleague and friend and past guest on the
1:04.7	podcast Dr. Dan Hooper of the University of Chicago and FermiLab for now can we
1:09.9	say what else is happening it will be announced next week so something else is happening by It will be announced next week. So something else is
1:13.5	happening by the time this comes out it'll be out there. We're actually in person
1:16.4	even though it looks like we're recording on Riverside. So how to damn there is.
1:20.9	So this is dueling laptops across the beautiful
1:24.6	edgy realm network.
1:26.6	So we have a new tradition since you've been on for your last book.
1:30.3	At the edge of time?
1:31.3	What was it?
