Seminar Polizzi Ada - Cosmic Inflation
November 20, 2024 16:30 - Physical Seminar Series Announcement!
The standard cosmological model, founded on the cosmological
principle, successfully explains most of the observable phenomena in
our universe. Nonetheless, the model faces some theoretical
challenges, particularly concerning the causality of events, which
cannot be ignored. One way to address these issues is the introduction
of an inflationary period preceding the Big Bang, driven by the
evolution of a scalar field known as the inflaton. Treating the
inflaton quantum-mechanically, its quantum fluctuations naturally give
rise to primordial density perturbations, providing an explanation for
the formation of structures, such as stars and galaxies. Can inflation
be considered a complete theory? Unfortunately not yet, it has some
unresolved issues and must face numerous test coming form current and
future observations. The problems of the standard cosmological model,
how inflation solves them and how it leads to primordial density
fluctuations are the main topics explored in this seminar which
concludes a course within the Excellence Program dedicated to master
degree students.
