Erik Peter Verlinde (born 21 January 1962, Woudenberg) is a Dutch theoretical physicistand string theorist. He is the identical twin brother of physicist Herman Verlinde. TheVerlinde formula, which is important in conformal field theory and topological field theory, is named after him. His research deals with string theory, gravity, black holes andcosmology. Currently he works at the Institute for Theoretical Physics at the University of Amsterdam.

At a symposium at the Dutch Spinoza-instituut on 8 December 2009 he introduced a theory that derives Newton's classical mechanics. This was followed by the publication of 'On the Origin of Gravity and the Laws of Newton' [1] on 6 January 2010. In his theory gravity exists because of a difference in concentration of information in the empty space between two masses and its surroundings; he also extrapolate this to General Relativityand quantum mechanics. He does not consider gravity as fundamental, but as an emergent phenomenon that arises from a deeper microscopic reality. He said in an interview with the newspaper de Volkskrant, "On the smallest level Newton's laws don't apply, but they do for apples and planets. You can compare this to pressure of gas. Molecules themselves don't have any pressure, but a barrel of gas has." See Gravity as an entropic force.

Verlinde's approach to explaining gravity apparently leads naturally to the correct observed strength of dark energy.[2] Previous failures to explain its incredibly small magnitude have been called the greatest embarrassment in the history of theoretical physics.[3]
