This is CBS I on the World with John Bachelor.

Here's John Bachelor.

Hotel Mars, episode N with Dr. Space himself, David Livingston.

I am John Bachelor, and we're going back in time.

13 billion years plus, to a discovery now written up very carefully by Aikos Bogdan,

astrophysicist at the Harvard Smithsonian Center for Astrophysics who joins us now to explain how you travel in time

that far back and what you learn not only of the fact itself 470 million years or so after the original bang, but that we're

discovering a black hole that far back.

Professor, a very good evening to you.

Congratulations on your revelation, but then again I don't

entirely understand what a black hole is doing at the beginning because I thought that

was the end of some things, not the beginning of things. Then again it's so close to the Big Bang.

This is the James Webb Space Telescope's discovery. What does it mean finding the oldest

black hole? What does that tell us, Aikos?

Good evening to you.

Hi, thank you very much for the invitation. I'm very glad to be here.

So what it tells us, it tells us that galaxies very early on in the universe did have big

black horse. These are great surprise that it's not only that they had black holes, but they had very massive black holes earlier in the universe.

And what we found here is that a very early galaxy, as you said, only 470 million years after the Big Bang

had a supermassive black hole which was nearly as massive as the galaxy itself.

And this discovery tells us how black holes may have forms.

So that is the main discovery. We better do a definition. What is a black hole and what is the theory of how it comes to be?
