Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

Time

Sidereus Nuncius

The specific astronomical moment — January-March 1610 — when the discoveries were made and reported.

Space

Sidereus Nuncius

The newly observed celestial space: lunar surface, Jovian system, Milky Way star clusters.

Matter

Sidereus Nuncius

Material lunar mountains, material Jovian satellites, material stars — the heavens disclosed as material like the earth.

Observer

Sidereus Nuncius

Galileo as the active observer with the new instrument; the European astronomical community as the implicit audience.

Energy

Sidereus Nuncius

The energies of telescopic observation; the institutional energies of patronage and communication that made the discovery public.

Information

Sidereus Nuncius

Discrete observational data: lunar drawings, orbital tables for the Jovian satellites, star counts in selected regions.

Internal Tensions

Where each work's argument pulls against itself.

Sidereus Nuncius

The pamphlet's reception was complicated: Kepler, the leading astronomer of the day, accepted the discoveries enthusiastically; Aristotelian academics resisted on the grounds that what the telescope showed could not be trusted against what Aristotle had taught. The discoveries supported but did not by themselves establish Copernican heliocentrism; Galileo's subsequent defense of Copernicanism (in the 1632 Dialogue) brought him into the conflict with Rome that the 1610 pamphlet had not yet provoked.
