Impossibility: the limits of science and the science of limits by John D Barrow — rest in peace — is an excellent book about the aspects of the Universe we can never know. For example, the visible Universe and whether constants are constant. When this blogger starts by pushing back on philosophers, I think they may mean scientists like Barrow, which is a shame because he makes for very compelling reading. In fact, have I not seen warnings here, from reputable posters, about this Backreaction blog? In any case, I recommend the ahem “philosophy” book heartily.
