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 publication year?1915
2. What is the discoverer?Albert Einstein
3. What are Einstein's field equations?They show that mass and energy make space‑time bend, like a heavy ball on a stretchy blanket. The equation Gμν = (8πG/c⁴) Tμν links this bending to the amount of mass and energy.
4. Why do heavy things bend space and time?The equations say that the presence and flow of mass‑energy dictate the curvature of space‑time, and this curvature tells objects how to move. So heavy things cause more bending.

Space-time manifold: A mathematical space that locally resembles Euclidean space but can have a more complex global structure.
Stress-energy tensor: A tensor that describes the density and flux of energy and momentum in space-time.
Geodesic: The shortest path between two points on a curved surface or in curved space-time.
