Well, he says here's the way to think about it.

This is how it always goes.

We've seen this before in the history of science.

Take Kepler.

And Kepler spent a long time trying to find an explanation for why the Earth is 93 million miles away from the sun.

93 million.

Kepler thought that has to be a really important number, a key to a deeper mystery.

But we now know that he was barking up the wrong tree.

Why?

There isn't just one planet.

There are many planets.

In fact, many planets around many stars.

And the distances of those planets from their host star varies over a wide range of possibilities.

That is progress.

That is understanding.

And then it frees you up to ask other kinds of questions, such as, what's the law of gravity?

What is the equation that allows us to understand how the sun forms?

So those are real questions.

And when you can toss out the ones that are red herrings that you thought were deep, but they're actually just asking the wrong question, that frees you up to make progress.

That would be pretty heavy and exciting to describe the underlying laws that govern all universes, regardless of their detailed features and what it would be like in that universe or that universe or that universe way over there.
