Lovelock gravity

(generalization of general relativity)

Lovelock gravity (Lovelock theory of gravity) is a mathematical model of gravity that is a modification of general relativity (GR), and which can differ from GR for spacetimes of dimension higher than four. It was devised by David Lovelock in the 1970s. It is of interest for theoretical exploration, and potentially of interest given that physics finds it plausible that more than three space dimensions might exist, those beyond the familiar being extremely curved to the point that they are microscopic and not perceived. Recent and improving observation of black holes makes comparison of observation with experimental models of gravity interesting.
