To the makers of music, all worlds, all times.

The record on the probe

Those words are hand-etched on the surface of the gold record aboard Voyager 1. The record is a 12-inch, gold-plated copper disc, and its aluminum cover carries a sample of uranium-238, which has a half-life of 4.468 billion years. Launched in 1977, the probe carries sounds and images from Earth, including about ninety minutes of music from many cultures.
No one has been able to change what it carries since it left, including the people who built it.

That makes the record a fixed snapshot of human culture from 1977. It proves that particular songs existed on Earth by that year, including a rock-and-roll guitar song from 1958. The uranium gives a finder a way to measure how long the record has been traveling, so the snapshot carries its own date. It makes no claim about which recording was best or first and says nothing about who owns any of them. It shows what existed and when.
Every listing of Earth's music made since can be edited, and the probe cannot be recalled to make an edit.

On 18 November, Voyager 1 will be one light-day from Earth, far enough that a radio message will take 24 hours to arrive. It was built in the hope that a stranger would find it and want to hear more.

The traveler

One traveler has taken that hope seriously. She heard the 1958 guitar song and decided to meet whoever played it, so she set out from a planet 25,000 light-years away. She passed Voyager 1 at the one-light-day mark and did not stop, because it was still transmitting.

She reached Earth expecting a distinctive sound and opened the local music services. One large service alone receives about 90,000 fully AI-generated tracks a day, and in June that was more than half of its new uploads.
She listened to the charts, then to a café, and everything sounded like the playlist at home.

"I have traveled 25,000 light-years for originality," she told the AI assistant through her earpiece, "and Earth sounds like an ordinary Tuesday on my planet."

The lookup

The AI assistant asked who she was looking for, and she said the guitarist from the probe's record. The registry has an artist record for Chuck Berry and several recordings of Johnny B. Goode. It also lists an artist named Chucko Berry and another named Chuck Barry, so the AI assistant asked which one she meant. She confirmed it was the one with the 1958 guitar.

ProofProfile works on the same principle as the probe. It holds nearly ten million recordings, drawn from music databases as they existed before 2022. It timestamps each record on the Bitcoin blockchain. Nobody can edit those records afterward, including the people who built the registry. The AI assistant returned the artist, the recording, the date, and a link to the evidence. Like the probe's record, the registry shows what existed and when. The AI assistant added that the date shows the record existed in that form on that day and says nothing about who made the song.

She asked whether a person had made it, and the AI assistant said the records could not tell her. She noted that this was the first party in 25,000 light-years to say it could not tell her. Software on Earth asks the same registry the same question through the antifraud service, which is now available, before it accepts or pays for a release. The service lists what the records show and leaves the decision to whoever asked.

The explanation

She stayed a week and asked the AI assistant why Earth sounded like home. The AI assistant explained that a generative music service turns a description into a song within minutes and that people tend to describe songs like the ones they already love. A million people asking for a slow guitar song at night get a million slow guitar songs, and they all sound as if they belong together. Her own planet had the same services and had reached the same result.

Her planet had also found a way to keep the originals findable. It kept a dated record for each song, so anyone could look up a recording and see that its record hadn't changed since the date it was fixed. Earth keeps birth records for people for a similar reason. She was pleased to learn that Earth had reached the same habit without her visit.

Before she left earth, she asked the AI assistant for a slow guitar song from her birth year, and it returned six. She liked four of them. The 1958 record was still in the registry, dated and unchanged, and she took the link home.
At the border, her ship's software asked for the purpose of her trip.

She replied that she had come for originality and had found the artist thanks to ProofProfile and Thor.
