In search of the invisible universe

Advances in cosmology in the 20th century have made huge leaps: the accelerating expansion of the universe, the Big Bang, sharp holes, supernovae, and so much more. However, the invisible dark matter, which is necessary to explain the movement of galaxies, the invisible dark energy, which is necessary to justify the acceleration of the expansion of the universe, but also the dark holes, which eliminate ordinary matter as fast as disappears a hare in his hat, they form the image of a universe that we are unable to capture, because we can not observe its ever-increasing size.

By shedding light on what is affectionately called the black triangle of Ia ignorance, the author tries to identify the prejudices that hide so much of the universe by analyzing a series of possible illusions. Is there really a shortage of matter in the universe? Can your observations be incorrect? Do we see a two-dimensional holographic universe in three dimensions? Or do we live in a black hole of cosmic proportions, in a bubble-universe or in a universe-island?  

In this highly comprehensible book, the leading astrophysicist David Elbaz examines the fundamental questions of modern cosmology in a completely different light.
