The Universe

Distinguish a galaxy, star, planet, organism and mineral.

Separate reconstructed history from conditional predictions.

Track matter through stars, planets and chemical systems.

Join origins-to-crystals with later evolution and possible futures.

Match a mechanism question with its focused field.

Compare planetary, stellar and galactic distances.

Connect finite propagation with seeing earlier events.

Place cosmic and geological stages in order.

Compare an estimate with its method and range.

Check whether images preserve distance and object scale.

Distinguish nuclei, atoms and compounds.

Connect emitted light with physical conditions.

Compare collapse, support and orbital movement.

Separate changing elements from rearranging chemical bonds.

Introduce relativistic context without treating singularities as observations.

Compare what optical, infrared and radio observations reveal.

Infer chemical candidates from characteristic patterns.

Distinguish measurements from their distance interpretations.

Connect material records with past formation conditions.

Compare explanations against several different observations.

Trace the element and mineral as different formation questions.

Record stellar spectra, planetary materials and rock context.

Connect element production, recycling and crystallisation.

Correct a crystal age confused with the age of its atoms.

Choose the next observation needed to support a link.
