Letter: Modifications to what kind of gravity?

Published 5 April 2017

From Ian Payne, Coulsdon, Surrey, UK

Mark Anderson (7 January, p 9) tells us that Erik Verlinde's new theory of gravity builds on Mordehai Milgrom's modified Newtonian dynamics (MOND) theory. But does the new theory still support space-time in which gravity is linked to the curvature of space? Does it have time dilation and does it explain the precession of Mercury? In other words, is it rather a Modified Einsteinian Dynamics?
