The mysteries of dark matter and dark energy may be evidence that we don’t fully understand the force of gravity. But when it comes to a force that has been studied mathematically and probed observationally for hundreds of years, what do we still need to learn? What questions are being asked? What research is pursued at the cutting edge? Would a new theory of gravity lead to a grand revolution in science, or do our present theories just need to be tweaked?
Rachel A Rosen is an assistant professor of theoretical physics at Columbia University. Her research focuses on gravity, quantum field theory and the intersection of the two. She is best known for her contributions to massive gravity, a theory in which the graviton — the particle that transmits the gravitational force — has a mass.Read More
Pedro G. Ferreira is Professor of Astrophysics at the University of Oxford. Originally from Portugal, he has studied and worked in London, Berkeley and at CERN in Geneva. His area of expertise is cosmology, focusing on the physics of the early universe and with a special interest in Einstein’s general theory of relativity.Read More
