Changing Views of Space Time and the Universe

This book explores how and why contemporary scientific knowledge undergoes conceptual shifts in its understanding of space time and the Universe. It argues for the substantive nature of spacetime and presents gravitational interaction not as a force field-unlike electromagnetic weak and strong interactions. The narrative revisits Einstein's so-called biggest blunder in light of his philosophical realism. It also examines how philosophical and aesthetic preferences influence modern cosmological theories. Finally the book offers a critical analysis of the three main versions of the Anthropic Principle.
