The Oscillating Universe: Einsteinian Cosmology of Black Holes and Gravitational Waves introduces the concept of cyclic cosmology within the framework of General Relativity. This book unravels the mysteries behind the Big Bang, the accelerating expansion of the universe, and the role of gravitational radiation and black holes in shaping our cosmos. With a comprehensive mathematical description of the oscillating universe and variable gravitational mass, readers will grasp the significance of the latest cosmological revolution sparked by the recent discoveries of gravitational waves.

Students, professional astronomers, and cosmologists will find this book to be a valuable resource. It offers a popular presentation of the history of modern cosmology, discussions on recent discoveries in the study of the universe, and an introduction to the cutting-edge cyclic cosmology theory. This book provides a unique opportunity to understand the evolving landscape of cosmology and the implications of cyclic cosmology.
