For over ten years, the dark side of the universe has been headline news. Detailed studies of the rotation of spiral galaxies, and 'mirages' created by clusters of galaxies bending the light from very remote objects, have convinced astronomers of the presence of large quantities of dark (unseen) matter in the cosmos. The most striking fact is that they seem to compromise about 95% of the matter/energy content of the universe. As for ordinary matter, although we are immersed in a sea of dark particles, including primordial neutrinos and photons from fossil cosmological radiation, both we and our environment are made of ordinary, 'baryonic' matter. Authors Mazure and Le Brun present the inventory of matter, baryonic and exotic, and investigating the nature and fate of matter's twin, anti-matter. They show how technological progress has been a result of basic research, in tandem with the evolution of new ideas, and how the combined effect of these advances might help lift the cosmic veil.
This book presents the progress in cosmic ray physics following the recent results obtained by balloon, satellite and underground experiments.

Besides, Williams and Terroux used in their work RaE, a source which does not emit γ rays. Meitner-Filipp published their observation in 1933 and certainly did not use the Wilson chamber combined with a magnetic field until 1932.
Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremesâ€"the very large ...
Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.
It is also one of the foundations of the standard cosmological model. This book presents the state of the art in building and testing particle models for dark matter.
As it is demonstrated throughout this book, once the existence of aether is accepted and its effects are taken into account, many unresolved issues regarding past, present and even future of this universe can be explained and readily ...
Describes the dark matter problem in particle physics, astrophysics and cosmology for graduate students and researchers.
It's impossible to read this book and look at either Earth or sky again in the same way.
They find that they simply cannot get to the observed patterns of galaxy clusters without including dark matter in the simulation. If one puts all the mass density into ordinary matter, the models give a Universe that looks completely ...
