On Mass, Spacetime Curvature, and Gravity
Janis, Allen I.
Physics Teacher, v56 n1 p12-13 Jan 2018
The frequently used analogy of a massive ball distorting an elastic sheet, which is used to illustrate why mass causes spacetime curvature and gravitational attraction, is criticized in this article. A different analogy that draws on the students' previous knowledge of spacetime diagrams in special relativity is suggested.
