Simone Malacrida

Simone Malacrida (1977) Ha lavorato nel settore della ricerca (ottica e nanotecnologie) e, in seguito, in quello industriale-impiantistico, in particolare nel Power, nell'Oil&Gas e nelle infrastrutture. E' interessato a problematiche finanziarie ed energetiche. Ha pubblicato un primo ciclo di 21 libri principali (10 divulgativi e didattici e 11 romanzi) + 91 manuali didattici derivati. Un secondo ciclo, sempre di 21 libri, è in corso di elaborazione e sviluppo.

INTRODUCTION

INTRODUCTION

This book presents a broad overview of black holes, starting from the mathematical and physical concepts that indicate their presence in spacetime up to their properties.

Among the most exotic celestial objects, black holes have represented an immense theoretical challenge for general relativity.

In fact, this discipline, born to describe spacetime at every point, without any distinction, must bow to the existence of singularities foreseen by the various metric solutions of its own equations.

For years there have been neither experimental findings nor physical theories capable of understanding the properties of black holes.

However, from the 1970s onwards, the application of quantum field theory to black holes has made it possible to understand some fundamental mechanisms such as Hawking radiation and the thermodynamics of black holes.

In addition, the refinement of some formalisms (Carter-Penrose diagrams for example) has allowed us to describe their main properties.

All of this is far from a comprehensive understanding of such celestial objects.

To date, there are no univocal theories that allow to describe what really happens in the presence of a spacetime singularity, mainly due to the fact that quantum general relativity has not yet been enunciated as a consistent physical theory.

The problems relating to black holes therefore intersect with other fundamental aspects of contemporary physics, such as the unification of forces, a probable theory of everything that explains the physical mechanisms of the Universe and
