Hello and welcome to Ways to Change the World. I'm Christian

Gerei Murphy and this is the podcast in which we talk to extraordinary people

about the big ideas in their lives and the events that have helped shape

them. My guest this week has some very big ideas.

Carlo Ravelli is a theoretical physicist.

He is an author, an opinion writer,

and he's sometimes called the poet of physics.

That he was called that by Alan Garner.

His sense of wonder obliterates the barrier between science and the arts

is the quote on the cover because his new book is called white holes

inside the horizon. If you've just about got your head around the idea of black holes

this takes you to the next level. I'm Ravelli, thank you very much for coming.

Thank you for having me.

It's a pleasure.

Now you've written a very small book

about a very, very big idea.

Could you, you know, why have you approached this topic? Why have you come to this topic?

It's a book, it's a bit different from my other books. I'm not talking here about what we have understood about the world, what physics knows about the world.

I'm just telling a story of the research I'm doing.

So it's about an hypothesis, an idea, not something I'm certain about or the community it's considered a very very probable.

It's more for describing what it is to try to get new ideas and push the boundary of what we know a little

bit farther.
