Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

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 theoretical framework?General Relativity
2. What is the mathematical formulation?Einstein Field Equations (Gμν = 8πG/c⁴ Tμν)
3. How does Einstein's theory explain gravity differently from Newton?Einstein said gravity isn't a force pulling objects; instead, heavy things warp the fabric of space and time, and objects follow the straightest paths in that warped fabric.
4. Why do planets like Mercury move the way they do?The bend of spacetime near the Sun makes Mercury's orbit shift a little each year, which Newton's equations couldn't explain.

Manifold: A geometric space that locally resembles Euclidean space.
Geodesic: The shortest or longest path between two points on a curved surface or spacetime.
Stress-Energy Tensor: A mathematical object describing the density and flux of energy and momentum.
