The twentieth century elevated our understanding of the Universe from its early stages to what it is today and what is to become of it. Cosmology is the weapon that utilizes all the scientific tools that we have created to feel less lost in the immensity of our Universe. The standard model is the theory that explains the best what we observe. Even with all the successes that this theory had, two main questions are still to be answered: What is the nature of dark matter and dark energy? This book attempts to understand these questions while giving some of...
John Archibald Wheeler was born on July 9, 1911, in Jacksonville, Florida, and
passed away on April 13, 2008, in Hightstown, New Jersey; his influence on gravitational
physics and science in general will remain forever. Among his many and
important contributions to physics, he was one of the fathers of the renaissance of
Since their discovery was first announced in 1973, gamma-ray bursts (GRBs) have been among the most fascination objects in the universe. While the initial mystery has gone, the fascination continues, sustained by the close connection linking GRBs with some of the most fundamental topics in modern astrophysics and cosmology. Both authors have been active in GRB observations for over two decades and have produced an outstanding account on both the history and the perspectives of GRB research.
Astronomy is a difficult science and it is a challenge to understand even the
stars that compose the brightest system on the night sky: Sirius (α Canis
Majoris=α CMa). This is one of the nearest stars and the brightest one as
seen from Earth, with the exception of our Sun. At present, perhaps unfortunately,
stellar astronomy and in particular the study of the very bright
stars are not part of the mainstream astronomy research. The professional
attention is now focused on the cutting-edge of cosmology, the early Universe,
extremely distant galaxies, the “origins” theme, etc.
