Definition

With signature $(-,+,+,+)$ ,

ds^2 = -c^2dt^2 + dx^2 + dy^2 + dz^2.

All inertial observers agree on $ds^2$ , even though they disagree on separate time and space intervals.

A structured path through Lorentz symmetry, intervals, and proper time.

光速度不変から導かれる、時空の対称性そのもの。

The time measured by a clock moving along a worldline.
