Earth–Moon System Falsifiability Conditions

Any reconstruction involving Earth's earliest history must remain vulnerable to rejection if it fails to satisfy Earth–Moon system observations.

Condition One

Failure to accommodate observed lunar mass weakens the framework.

Condition Two

Failure to accommodate orbital and angular momentum constraints weakens the framework.

Condition Three

Failure to accommodate compositional and isotopic observations weakens the framework.

Condition Four

A competing model that explains the same observations with fewer assumptions should be preferred.

Scientific Function

Falsifiability improves reconstruction quality by narrowing the range of viable explanations.
