Understanding how the Universe works is the greatest challenge for the scientists today. The Einstein – Minkowsky’s space/time continuum concept is currently considered the most probable one. But this concept and theory, although accepted today by the great community of scientists as the best we have for now, is not certain itself. To make it compatible with the latest astronomical discoveries it generated the “creation” of strange entities such as dark matter and dark energy, black holes……… These were not yet proved to exist, as they were imagined. May be the structure and dynamics of the Universe is different? “A dual universe” tries to imagine another concept, maybe in a better harmony with the facts (astronomical observations). Can this concept be closer to reality? What is not proved to be impossible, it may be possible!
