Scope and limitsEarliest located among the texts found by the pack’s searches of 2026-10-28 and the cross-family check’s bounded search of 2026-10-29/30; not a claim that no earlier text exists. From a proponent, which states the challenge while arguing the concept is not precluded by physics; the paper states that cooling would be achieved through heat pipes and radiators. A candidate is open: the check found that a Nature Electronics Perspective on carbon-neutral data centres in space (published online in October 2025, read in an author-hosted proof) discusses passive cooling as insufficient; whether it states a significant constraint, as the criterion asks, and in which expression, is not confirmed.

Source excerpt

“the core concepts of space-based ML compute are not precluded by fundamental physics or insurmountable economic barriers. However, significant engineering challenges remain, such as thermal management, high-bandwidth ground communications, and on-orbit system reliability”

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.
