Albert Einstein’s general theory of relativity states that space can be curved by large masses, such as the sun. Einstein suggested that if a beam of light from a distant star passed near the sun, the light’s path would be bent as it passed through the curved space. A later experiment showed that Einstein was correct. What science skill was Einstein using when he described a beam of light from a distant star would be affected by curved space?
What is a prediction
