According to the General Theory of Relativity, which entities can participate in gravitational interactions?
Answer:
material objects and electromagnetic radiation only
Albert Einstein's General Theory of Relativity posits that gravity is the curvature of spacetime caused by mass and energy. Since electromagnetic radiation possesses energy, it contributes to the stress-energy tensor, thereby influencing spacetime curvature and interacting gravitationally. Thus, both material objects and electromagnetic radiation are subject to gravitational effects, making option B the most comprehensive and accurate description within the framework of relativistic physics.
