We can reformulate it for the ocassion as: "We know > the interference pattern produced by two streams of light, but what > is the interference pattern of one stream of light?" A diffraction pattern. > Or better yet: > "We know the gravitational effect between two material bodies, but > what is the gravitational effect of one material body?" Curves the metric. But without any other body in the universe there's nobody there to measure it. If a tree falls in a forest and there's nobody there to hear it, does it make a sound? Same question wearing different clothes. In both cases it's just semantic games with an undefined term. In the question regarding the tree, the phrase "make a sound" was never defined and so the issue appears debatable. In your example, the word "effect" was never defined, and so the question appears debatable. > > Think about that. Best regards, Mauro
