“Since the mathematicians have invaded the theory of relativity, I do not understand it myself anymore.” ~Albert Einstein

Pedro G. Ferreira’s The Perfect Theory is an astrophysics primer for those of us who have only a precarious grasp on general relativity, quantum mechanics, dark matter, and theoretical physics.

Being the curious novice that I am, I appreciate Ferreira’s reminder that there is no single unifying theory that incorporates all things cosmic. Every concept seems to have at least one detractor, foible or bugaboo. Then again, if it wasn’t intellectually challengeable, cosmology wouldn’t be a science—it would be a religion.
