Claim · 2026-03-29 · publication · Stated in source · Supported

Marcy's preprint (March 2026) argues that kilometre-scale orbital computing arrays would alter the night and daytime sky and increase the likelihood of collisions that could trigger runaway debris production.

One recorded claim. The claim panel gives its qualification, the source passages with their place in each source, and how it was checked.

Check notes: Candidate pack passage, compute, power and orbit (research/compute-power-orbit). The paraphrase is Selekoa’s, written from the text retrieved for the candidate pack on 2026-10-28; it is not a quotation and was not machine-matched. The cross-family check found it faithful. Locator corrected at admission: the “technically attractive” wording is in the Introduction on page 1, not in the abstract (cross-family check, item 110). A cross-family machine check (2026-10-29/30, item 110) re-read the record’s sources and found full support. No human editorial review.

Status and meaning

Editorial status. Not reviewed by an editor. An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.

Relation. A passage of the document meets the proposition’s criterion. The record documents what the text states, in its register (fiction and satire are labelled); it is not evidence that the proposition is true and implies no influence on or from another text.

Date. Date of publication, as the source gives it.
