Dimension-by-Dimension Evidence

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

⧖

Time

Gravitation

Relational spacetime time — depends on reference frame.

✦

Space

Gravitation

Curved spacetime — gravity as geometric structure.

◉

Matter

Gravitation

Mass-energy as source of spacetime curvature.

◎

Observer

Gravitation

The physical observer in a reference frame.

⚡

Energy

Gravitation

Mass-energy equivalence; conservation in physical interactions.

⧉

Information

Gravitation

Lawful structure of spacetime physics.

Internal Tensions

Where each work's argument pulls against itself.

Gravitation

The relation between general relativity (MTW's subject) and quantum mechanics remains unresolved; the search for "quantum gravity" continues.
