Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain the theory of relativity and its two parts, relay key concepts, predictions and tests from physics references, describe formulations and applications, and distinguish relativity from quantum mechanics, Newtonian gravity and popular misconceptions.

The physical theory developed by Albert Einstein comprising special relativity of 1905, which relates space and time in the absence of gravity through the constancy of the speed of light and treats events in a unified spacetime, and general relativity of 1915, which describes gravity as the curvature of spacetime by mass and energy, predicting phenomena such as the perihelion precession of Mercury, gravitational lensing, time dilation, black holes with their event horizons and gravitational waves, all since confirmed; relativity underpins modern physics, cosmology and technologies such as GPS.

What it is for: Not applicable; a scientific theory.

It can be explain special and general relativity; relay concepts and tests; describe applications; distinguish from other theories.

Distinguishing features

Constancy of light speed

Spacetime

Gravity as curvature

Confirmed predictions

What it looks like

Not a visible object; a physical theory.

Physical character

special relativity: 1905 year

general relativity: 1915 year

Mercury perihelion excess: about 43 arcseconds per century

first gravitational wave detection: 2015 year - LIGO

How it is recognised

Einstein s theories of space, time and gravity

Special and general relativity, spacetime events, horizons, perihelion precession of Mercury, formulations of special relativity

Newtonian gravity is the limit at low speeds and weak fields; quantum mechanics governs the very small; unification is unsolved

What the second pass must settle

  • Should special relativity, general relativity and black hole be separate primary entries?
  • How should physics references be linked?
  • The registry entry has merged aliases naming predictions and concepts; should they be split off?
