Stephen Hawking and a new vision of the Universe

ABSTRACT. It is definitely an arduous challenge to describe in few words a person who has been considered the greatest physicist of nineteenth century. Research focused on the complexity of the Universe, Big Bang and Black Holes Theories, on the age of the Universe, on the Chronology of the Universe, on the hypothesis of Multiverse, the study of galaxy formation and evolution, as well as the cosmological inflation. His diversified activity has contributed to the scientific disclosure of several physical and astronomic theories, which have been presented in an engaging way to the audience. The essential bibliography invites the reader to appreciate the interdisciplinary and international qualities of his collaborations opened to the possibility of existence of other Universes.

Professor Stephen Hawking: an appreciation by Lord Rees

ABSTRACT. In this paper, the Astronomer Royal and former Master of Trinity College, Lord Martin Rees, pays tribute to Professor Stephan Hawking, reminiscing the significant events of his life. The focal point of the essay is Hawking’s manifestation of willpower and determination in face of the deadly disease he was diagnosed with at the age of 22. Amongst some of the most significant achievements, Rees mentions Stephen’s ‘eureka moment’, namely when he unexpectedly discovered a link between gravity and quantum theory, predicting that black holes would not be completely black, but that they would radiate in a distinctive way. According to Hawking, this radiation is only significant for black holes because they are less massive than stars – and none of these have been found. ‘Hawking radiation’ theory had very deep implications for mathematical physics and one of the main achievements of string theory has been to corroborate his idea.

Medium of natural phenomena

Looking for the deeper essence of natural phenomena and minimal number of physical laws describing them, a hypothetical vacuum medium is stratified into structural layers, as the levels of observation of respective processes. Instead of a fluidic, the dielectric medium successfully explains all EM phenomena at least. More or less convincingly, inertia and gravitation are explained on EM bases, and the speed of light propagation, with respective reference frame, is conditioned by gravitation itself. The unification of physics is thus initialized, just on the advanced classical bases.
