A slide projection ofthe moon's dry, gray surface rakes across the ceiling above the installation. The Sea of Tranquility is one of the moon's dark regions, thought by ancient astronomers to be oceans. Fukawa says he thinks of his son and his friend's daughter as being just as distant and as misunderstood. "Erika is right there in front of me but also as far away. So close but so far away."

In his imagination,Fukawa tries to experience the moon's isolation via its silence. "There is no air, no sound. Every couple hundred years, maybe a small piece of space debris hits the surface, a cloud of dust puffs up, but everything is silent." Silence, he knows now, through his experience with Fumi and Erika,is not a void, but a dense containment, like a black hole, of all that is known but can't be expressed.
