It looks like it's actually changing, which is really amazing, which adds still more speculation as to what this dark energy actually is, because you have to account for the fact that it looks like the universe doesn't have a constant cosmological constant.

No, it just means that lambda, the number that he had put as a number, is a function of time.

It changes the equations.

It means that Albert was just – and he himself admitted it.

It was a temporary thing that made the equations work.

He had no idea if there was anything physical about it.

Right.

And so now we're actually trying to see whether Albert's prediction of its existence is leading to something physical.

And so the fact that it might be dependent on time or the age of the universe is further evidence that it is something physical and not just mathematical.

Oh, snap.

Yeah.

Okay.

Absolutely.

95% of the material in the universe is still wholly unknown to human science.

Yeah.

I use the term material to be as general as possible.

I didn't call it matter.

I didn't call it energy.

I didn't call it particles.

Right.
