I am a 14 year old who is independently studying physics. Ihave finished theCarroll's general relativity book:, Spacetime and Geometry: An Introduction to General Relativity by Sean Carroll. I am specifically interested in cosmology, so is there any book which goes more in depth into cosmology.? I prefer a mathematically rigorous book, which goes beyond the cosmology chapter in Spacetime and Geometry: An Introduction to General Relativity by Sean CarrollCarroll's book. The Big Bang and inflation theory should be dealt with in depth.
