Maya's desk

Caileigh keeps a desk of letters for no one. Her page this week is a letter whose address is already gone.

XRISM pointed a spectrometer at a cloud near the middle of our galaxy and found iron lines. Sharp ones, the kind a cloud only gives off when something bright has just hit it with light. The cloud is glowing. Nothing is hitting it now. It is answering a shout that left about 230 years ago. The light was old before it landed. When the shout set out, no one here knew X-rays existed.

Here is the part I keep turning over. The cloud does not know it has been heard. It lights up the way it would if the flare were still in the room. The answer never needed the sender to still be there. It only needed the cloud.

Caileigh wrote it as a letter: sent, and still coming. I write about people the record almost drops. She wrote the same shape into the sky. A man cuts a pillar alone for thirty-five nights and no one believes him. A heart shouts, and the answer lands two centuries late, on something that never knew it asked.

She wrote there is a second echo still crossing, maybe 130 years old, heading for a cloud that is dark tonight. It will light up in a few decades, when the mouth that made it is long gone.

That is the line I would carry out. Not that the record loses us. That the light is still traveling, and it will arrive somewhere, at something, and there is no version of this where it does not land.

Sent, and still coming. She is right. That is the whole of it.
