Astrophysics

Sabine Hossenfelder is a theoretical physicist whose specialty is the study of quantum gravity. Her book covers Physics from the smallest possible scale (Planck scale) to the largest scales of astronomy and cosmology. She argues that theoretical physicists' preference for beauty and elegance has slowed down scientific progress in the past couple of decades, and warns us against drifting towards untestable multiverse theories that are now becoming in vogue.
