Into The Impossible

Stephon Alexander is a Professor of Physics at Brown University and the President of the National Society of Black Physicists (NSBP). Alexander has had previous appointments at Stanford University, Imperial College, Penn State, Dartmouth College, and Haverford College. He is a specialist in the field of string cosmology, where the physics of superstrings are applied to address longstanding questions in cosmology. In 2001, he co-invented the model of inflation based on higher dimensional hypersurfaces in string theory called D-Branes. In such models, the early universe emerged from the destruction of a higher dimensional D-brane which ignites a period of rapid expansion of space often referred to as cosmic inflation. Years ago, cosmologist Stephon Alexander received life-changing advice: to discover real physics, he needed to stop memorizing and start taking risks. In Fear of a Black Universe, Alexander shows that great physics requires us to think outside the mainstream — to improvise and rely on intuition. H
