Determine whether the Universe is finite or infinite

Determine whether the Universe is truly infinite, resolving the question identified as remaining open between mathematics and metaphysics.

Background

The chapter uses the contrast between the potentially limitless Universe and the finite, increasingly congested region of near-Earth space to motivate concern about orbital sustainability. In doing so, it explicitly notes that the global question of whether the Universe is infinite has not been resolved. This is an unresolved foundational question rather than a problem directly developed through the chapter’s space-governance analysis.
