By nightfall, a cluster of twinkling points could be seen flying across the sky every couple of hours. You could distinguish them from the usual stars because, on careful inspection, someone could make out the shape of each point. They were each a small cuboid. They all, in their own orientations, spun on their own axes. As a result, they reflected the sunlight and twinkled at different rates.

People thought for a long time, but were never quite able to adequately describe these small objects in space. Finally, a reporter came up with an analogy that got some traction.

“They’re like a handful of crystalline dominoes scattered by a space giant.”

A Dialogue Between Two Artists

“We ought to have a chat,” Yan Dong said.

“I asked you to come just to do that, but only about art,” the low-temperature artist said.

Yan Dong stood on a giant block of ice suspended five thousand meters in the air. The low-temperature artist had invited her here. The helicopter that had brought her had landed and now waited to the side. Its rotors were still spinning, ready to take off at any moment.

Ice fields stretched to the horizon on all sides. The ice surface reflected the dazzling sunlight. The layer of blue ice below her seemed bottomless. At this altitude, the sky was clear and boundless. The wind blew stiffly.

This was one of the five thousand giant blocks of ice the low-temperature artist had taken from the oceans. Over the past five days, it had taken, on average, one thousand blocks a day from the oceans and sent them into orbit. All across the Pacific and Atlantic oceans, giant blocks of ice were being frozen and then carried into the air to become one of an increasing number of glittering “space dominoes.” Tidal waves assaulted every major city along the world’s coasts. Over time, though, these disasters became less frequent. The reason was simple: The sea level had dropped.

Earth’s oceans had become blocks of ice revolving around it.

Yan Dong stamped her feet on the hard ice surface. “Such a large block of ice, how did you freeze it in an instant? How did you do it in one piece without it cracking? What force are you using to send it into orbit? All of this is beyond our understanding and imagination.”

The low-temperature artist said, “This is nothing. In the course of creation, we’ve often destroyed stars! Didn’t we agree to discuss only art? I, creating art in this way, you, using small knives and shovels to carve ice sculptures, from the view from the perspective of art, aren’t all that different.”

“When those ice blocks orbiting in space are exposed to intense sunlight, why don’t they melt?”
