No, I mean, I agree. What can I say? In fundamental physics, we've not had any breakthroughs that have been verified experimentally for a very long time. That's just true. Can't argue with that.

0:13.4

What if the past 40 years of fundamental physics research have been leading us down a dead end?

0:23.4

What if there's something historically and structurally rotten that's holding us back from understanding the true nature of reality?

0:29.9

In this conversation with Professor Sean Carroll, a renowned physicist, philosopher, and author

0:35.4

who's been at the forefront of some of the most exciting

0:38.4

and controversial developments in modern physics. He reveals the truth behind how he sees

0:44.5

the supposed crisis in fundamental physics. In 2023, Sean stirred up the physics community

0:50.6

with his episode on the crisis in physics, arguing that there is no crisis.

0:56.2

Some professors cheered him on, while other professors stated that he straw-maned their views,

1:01.7

defending physics as a whole, rather than their criticisms about fundamental physics specifically.

1:07.1

Today, Sean Carroll clears the air, all while explaining other heated topics, such as where the laws themselves come from and what it means that our universe is a hologram.

1:18.0

What might the next revolution in physics look like?

1:23.2

How are you doing today, sir?

1:25.2

Doing well. Thanks for having me on.

1:27.2

What's something you're working on that you're excited about?

1:31.0

Oh, you know, I always tend to work on bunches of things at once.

1:36.0

We have a paper that I'm part of, although the main emphasis comes from Oliver Friedrich, who is a postdoc in Germany, on phenomenal

1:48.7

logical consequences of holography. So holography, you know, I don't want to go too much into it,

1:54.4

but the holographic principle is a big thing in physics and in quantum gravity. It says that,

1:59.8

you know, there's a lot less going on in the world than you might think.

2:03.6

The world is not really three-dimensional space. It can be thought of as a two-dimensional space with densely encoded quantum information, and we're just a projection of that into the world.

2:14.2

And so Oliver and a bunch of us tried to propose a way that that would actually make a difference for experimental signatures.
