Gonzalo J.A. Cosmic Paradoxes

WSPC, 2022. — 249 p.In the Third Edition of this book, almost coincident with the launch reports of NASA's James Webb Space Telescope (JWST), includes recent work discussing evidence in favor of an open finite universe. A further discussion of the Heisenberg–Lemaitre time (Appendix D) takes into consideration that the cosmic expansion velocity at very early times is Ṙ(yHL)≫c and reviews in more detail the thermal history of the universe.Foreword
