I sent Sisyphus exploring the nooks and crannies of the interactive version of Holding Up the Sky , but there were no buried references, no hints of more to come. And no public database on the planet contained a single entry on the ACs. Every cult employed image managers to try to keep the right spin on their media representations … but total invisibility suggested extraordinary discipline, not expensive PR.

The cult of Anthrocosmology. Meaning: Human knowledge of the universe? It was not an instantly transparent label. At least Mystical Renaissance, Humble Science! and Culture First didn’t leave you guessing about their priorities.

It did contain the H-word, though. No wonder they had opposing factions – a mainstream and a fringe.

I closed my eyes. I thought I could hear the island breathing, ceaselessly exhaling – and the subterranean ocean, scouring the rock beneath me.

I opened my eyes. This close to the center, I was still above the guyot. Underneath the reef-rock was solid basalt and granite, all the way down to the ocean floor.

Sleep reached up and took me, regardless.

Chapter 15

I arrived early for Helen Wu’s lecture. The auditorium was almost empty – but Mosala was there, studying something on her notepad intently. I took a seat one space removed from her. She didn’t look up.

“Good morning.”

She glanced at me, and replied coldly, “Good morning,” then went back to whatever she was viewing. If I kept filming her like this, the audience would conclude that the whole documentary had been made at gunpoint.

Body language could always be edited.

That wasn’t the point, though.

I said, “How does this sound? I promise not to use anything you said about the cults, yesterday – if you agree to give me something more considered, later on.”

She thought it over, without lifting her eyes from the screen.

“All right. That’s fair.” She glanced at me again, adding, “I don’t mean to be rude, but I really do have to finish this.” She showed me her notepad; she was halfway through one of Wu’s papers, a Physical Review article about six months old.

I didn’t say anything, but I must have looked momentarily scandalized. Mosala said defensively, “There are only twenty-four hours in a day. Of course I should have read this months ago, but … ” She gestured impatiently.

“Can I film you reading it?”

She was horrified. “And let everyone know?”

I said, “‘Nobel laureate catches up on homework.’ It would show that you have something in common with us mortals.” I almost added: “It’s what we call humanization .”

Mosala said firmly, “You can start filming when the lecture begins. That’s what it says on the schedule we agreed to. Right?”

“Right.”
