This is an early dark energy that would have explained the Hubble tension.

Early dark energy.

It still could be evolving.

And again, this is early data.

There's going to be a lot more coming in the next... And just to...

Well, I think that's fair.

I think we know very little about what the future evolution of the universe is going to be.

Will dark energy decrease with time?

Is it constant?

Is it Einstein's cosmological constant?

And I think these are empirical questions right now because we don't have a good theory.

And ultimately, we do hope that there will be a fundamental theory.

But right now, we're being guided by observations.

And the observations that it's decreasing with time, evolving with time and getting faster.

less um there's less of it now uh that that's new and um there are many more experiments on the drawing board that will they will test that and we'll see how it how it lands now isn't there a dark matter telescope coming online that's been called that's the vera rubin telescope oh wait what's the what's the nancy grace roman telescope what's that one

That's a survey telescope.

It's a NASA telescope in space.

Originally, the Vera Rubin Telescope.

It started out probably 30 years ago almost.

I think that's precisely the question we want to answer.
