Question

Quizplus · Accepted Answer

This is due to the principle of equivalence in general relativity, which states that the effects of gravity are indistinguishable from the effects of acceleration. Therefore, astronauts would feel as though there is a local gravitational force acting on them, similar to being on the surface of a planet.
