theory of relativity
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.
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.
