"The rabbit hole gets wrestled here. An old school saying the more you know, the more you don’t know. Dance along this read into the unknown and find out that this book may be the best ever answer to ‘What is soul?'" —Chuck D, rapper and co-founder of Public Enemy *Starred Reviews* from  Kirkus  and  Publishers Weekly ! Named a Best Book of 2021 by  Library Journal , Kirkus , and  symmetry  Magazine In this important guide to science and society, a cosmologist argues that physics must embrace the excluded, listen to the unheard, and be unafraid of being wrong.   Years ago, cosmologist Stephon Alexander received life-changing 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. His approach leads him to three principles that shape all theories of the the principle of invariance, the quantum principle, and the principle of emergence. Alexander uses them to explore some of physics' greatest mysteries, from what happened before the big bang to how the universe makes consciousness possible. Drawing on his experience as a Black physicist, he makes a powerful case for diversifying our scientific communities. Compelling and empowering, Fear of a Black Universe offers remarkable insight into the art of physics.
