Is the Moon much closer than we think?

Bring the sky down to street level.

Give the theory a number. Not 'nearer than they say,' but a proposed distance or altitude and a description of the object. That lets two observers ask where it should appear at the same moment. The nearer the model places it, the more important that shared-view test becomes.

Parallax is the change in apparent direction with viewpoint. The NASA visualization explains the geometry; NIST describes distance measurement. Neither should be mistaken for a field experiment we personally conducted. They provide a framework for the experiment the local claim needs.

An observer-dependent display can be proposed instead, but now the theory owes you a mechanism for producing those different views. Don't let one model retreat into another without noting the switch. A nearby object is a fascinating claim precisely because its position ought to be vulnerable to measurement.

A distance you can disagree with.

NIST outlines astronomical distance methods, including timing a return signal. Parallax supplies a separate geometric constraint when observers have a known separation.

Our reading: a claim that the Moon is much closer is testable if it commits to a distance. Without a distance, the model can slide out of reach of every comparison.

Choose before measuring.

For a fixed baseline, a nearer object should show a larger angular displacement. Real observations need synchronization, coordinate alignment and uncertainty estimates; a screenshot of two unrelated nights will not do.

A proposed local object must also explain the laser-ranging record. Combining constraints is the point: adjusting distance to fit one image while ignoring the timing is not a complete model.
