So that's, again, when gravity is weak, right? So I asked myself... Of course, we know in field theory, new effects should show up when fields are strong, not weak. But let's throw that out of the window. Can I write down a theory where gravity alters when it is weak? And we've already said what gravity is. What is gravity? It's the curvature of spacetime.
