Anti-de Sitter space bell. It might be described as being the "opposite" of the surface of a sphere, which has a positive curvature. General relativity is a theory of the nature of time, space and gravity in which gravity is a curvature of space and time that results from the presence of matter or energy. Energy and mass are equivalent (as expressed in the equation "E" = "mc"), and space and time can be translated into equivalent units based on the speed of light ("c" in the "E" = "mc" equation). A common analogy involves the way that a dip in a flat

In the end, the singers float in the air, continuing to wonder what sound the fox makes, while failing to notice a computer-animated fox behind them, which stands on its hind legs and scat sings (voiced by Vegard), answering their question.
