Boyer-Lindquist coordinates are a specific way of expressing the spacetime around a rotating black hole, particularly the Kerr black hole solution in general relativity. These coordinates are a modification of spherical coordinates that take into account the effects of rotation and are particularly useful for analyzing the properties of rotating black holes. In Boyer-Lindquist coordinates, the spacetime is described using four coordinates: 1. **Time (t)**: Represents the time coordinate for an observer at infinity.
