We have a kid now and another on the way and—the idea is, the hope is—that we are, at least in a technical sense, adults. We’d always assumed we would know more, would have accomplished more, by the time we got to this point, assumed we would have turned into different people, better people. That was the idea. That was the hope. Looking back over our shoulders, we can see the track stretching out behind us, an unbroken line from where we got on to where we are now. The voice of the American ride says: Please keep your attention focused in a sideways direction.

His name was Two-Tongued Jeremy; he was a monitor lizard with a forked tongue, thick glasses, and a wild, wagging smile meant to convince children that learning could be fun, too. He came highly rated. He updated automatically. When our promising children propped their tablets against their stacks of textbooks, their glazy angelic eyes took on that ferocious determination we liked to see in ourselves.

You ask how my brother died on the moon that day, but that’s the wrong question. Ask instead what he spelled with his bootprints when we first stepped down from the platform. Ask instead the one song he listened to, the whole flight there. Ask why he wanted me there instead of Jess, his wife. It’s because we used to pretend the backyard at night was the moon. That we were astronauts. That gravity was different.

Once upon a time, there was a princess named Little Snowdrop, who had six brothers and four sisters. Her brothers were ravens, and her sisters were swans. Whenever they wished, they would fly around the castle on their black or white wings, but Snowdrop, not having any wings of her own, could not join them. She could only wave at them from the window of a high tower as they flew by. Her father was the King, and he loved her very much.

When I finally visit Hugh Everett, it’s 1982. We sit down and pahnah pours himself a glass of sherry and lights a cig before asking me about the purpose of my visit. We’re in Hugh’s bedroom. He’s sitting on his bed, in full suit and tie, taking deep drags from his cigarette. I take a seat in a chair next to the window. I tell him I want to hear about his theory. This isn’t true. I know his theory well.

We are familiar with gold, says Hume, and also with mountains; therefore, we are able to imagine a golden mountain. This idea may serve as an origin myth for Iram, the unconstructed city.
