Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the related metric?Schwarzschild metric
2. Why did scientists create Boyer–Lindquist coordinates?To simplify the equations that describe a black hole, so they can be solved more easily.
3. How do Boyer–Lindquist coordinates help with black holes?They separate the radial part from the angular part, letting scientists study how objects move and how light bends near a black hole.

Schwarzschild Metric: The simplest mathematical solution to Einstein's field equations describing the spacetime around a spherical, non-rotating, uncharged mass.
Geodesic Equations: Mathematical equations that describe the paths of objects moving freely under the influence of gravity in curved spacetime.
Spacetime Curvature: The distortion or bending of the fabric of spacetime caused by the presence of mass and energy, which we perceive as gravity.
