According to the most accredited cosmological model, the Universe is composed of two-thirds dark energy, a mysterious form of energy that, in opposition to gravity, generates a repulsive force and is accelerating the expansion of the Universe. A recent study by the Astrophysics and Cosmology group at SISSA, published in The Astrophysical Journal and led by Professor Andrea Lapi, challenges this conventional view: a new approach, which introduces “noise” during the evolution of the Universe, allows for an explanation of its acceleration without modifying general relativity or invoking dark energy.
