This is CBSI on the world.

Behind the Black, Bob Zimmerman, it's here, the biographer of Hubble, Universe and Amir.

And now, Bob, what is the Hubble constant?

All right, well, the Hubble constant is named after the same thing in Hubble Space Telescope

is Edwin Hub, Hubble, Telescope is, Edward Hubb,

Hubble, an American scientist astronomer from the early 20th century. He determined that the universe was expanding. And it was expanding at a rate that was not certainly known in the past.

But nonetheless, the space between the stars was actually stretching apart.

That's what he discovered, that galaxies are flying away from each other.

The problem the scientists and astronomers now for a century is determine exactly what that

expansion rate is.

And a lot of it is based on believing in the hypothesis that the universe began as

the Big Bang 13.7 billion years ago, and the expansion has been going on since then. The problem

scientists have is that in the early universe, when they measure the Hubble constant, they come up

with one number, a lower number. But when they measure the Hubble constant, they come up with one number, a lower number.

But when they measure information from the nearer universe, they come up with a higher number.

And new data, that I post on Behind the Black last week, says that the newer data from the near

universe is more precise, has become more precise, and the

older data from the early universe has become more precise, but the two numbers are different,

and they don't match, and they're not coming together. And this is a problem. It suggests

that something is wrong with the cosmology and the theories, and we don't know

what it is.

We really do not know what it is.
