Lorentz transformation is a part of Special relativity.

Open Mass–energy equivalence →
mass–energy equivalence is part of special relativity.
Mechanism: Mass–energy equivalence (E=mc²) is a result of special relativity: mass and energy are two forms of the same thing, interchangeable at a huge exchange rate.

Open Speed of light in vacuum →
speed of light in vacuum is part of special relativity.
Mechanism: The speed of light is the cornerstone of special relativity: it is the same for every observer, which forces space and time to bend to keep it constant.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: 7 of 7 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 6 → 24 → 54 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 6 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to General relativity, Spacetime, Speed of light in vacuum and Mass–energy equivalence.
Through this lens it connects to General relativity, Spacetime, Lorentz transformation and Mass–energy equivalence.
Technical detail
Special relativity rests on two postulates: the laws of physics are the same in all inertial frames, and the speed of light is constant for every observer. From these follow time dilation, length contraction and the relativity of simultaneity, unified in the geometry of Minkowski spacetime via the Lorentz transformation. Mass and energy are equivalent, E = mc².
