Anti de Sitter space

Some of the differences between the familiar Newtonian equation of gravity and the predictions of general relativity flow from the fact that gravity in general relativity bends both time and space, not just space. In normal circumstances, gravity bends time so slightly that the difference between Newtonian gravity and general relativity that results is so slight that it is impossible to detect without scientific instruments.
