But Professor Erik Verlinde, an expert in string theory from the University of Amsterdam and the Delta Institute of Theoretical Physics, thinks that gravity is not a fundamental force of nature because it’s not always there. Instead it’s “emergent” – coming into existence from changes in microscopic bits of information in the structure of spacetime. Verlinde first articulated this groundbreaking […] Read More
