You somehow are feeling that the math is a clue

that everything follows your math.

If at some point the maths collide and then the universes collide, then that would be very unsettling to both of you, I would assume.

Well, I thought it would be fair to ask the author of the article, so I called Alan, who happened, as it turns out, to be in Phnom Penh, Cambodia.

And I sent him the interview with Brian.

He listened.

And I asked, well, what do you think about Brian's argument?

He said, well, I think it's going to be much harder than Brian thinks to actually sense or encounter or measure these other universes if they exist at all.

What does that mean?

And that we'll never, ever really understand everything?

Recently, I got into a bit of a kerfuffle with a guy who yearns like you do for an ideal.

His name is Jim Holt.

And he wrote this really good book called Why Does the World Exist?

And just to get us started, in that book, he quotes a poem.

Meaning what?

Yeah.

Minerals?

I'm really asking is what is the most essential nature of the rock?

So if you look deep, deep, deep down into the rock, do you find something concrete?

Do you find a little bit of thing?
