This is a podcast on Cosmology and modified theories of gravity. Guest speaker Sergio Sevillano is a theoretical physicist from Durham University, UK. He is doing his postdoctoral from The Institute for Particle Physics Phenomenology, Durham Univerisry. His specialization lies in scalar-field dynamics and their impact on the late-time Universe. To know more about him, look here:

String theory has yet to make a testable prediction, which makes me skeptical about its viability.
