And between us and the star, you know, there's nothing.

It's empty, right?

So we can't literally hear the frequencies of the waves, but we see the up and down motion.

And so that is actually connected.

The frequency of the sound waves created by these up and down motions is connected to the physics and also the chemical composition of the star in its interior.

So we can't literally dive into the stellar concert hall, but we can measure the frequencies from a distance, let's say.

Yeah, yeah, yeah.

That's fantastic.

Sometimes I give lectures for musical artists, and then they are all totally fascinated about these sounds.

Let me test this on Matt.

Yeah, so we actually just shift.

I mean, each star has its own symphony, right?

Depending on how big it is, how much mass it has, how old it is, it has its own symphony.

But then we shift that global symphony into the audible range of humans.

That's called sonification.

It's a whole field by itself.

And actually, it allows blind people to be astronomers.

I find that I'm a very, for me, inclusion is very important.

So in this way, we can reach people who can't see, but they can hear the stars.

But we have to help them a little bit by shifting to the audible range.
