  • Using the first data release of the Dark Energy Spectroscopic Instrument (DESI), this study demonstrates that galaxy correlations follow a power-law decay without transitioning to spatial homogeneity up to scales of approximately 400 Mpc/h, with density fluctuations exhibiting extreme-value statistics rather than the Gaussian distribution expected for a homogeneous universe. In short: The universe isn’t…

About me
I am a physicist, and I got my degree at the university of Rome Sapienza and my Ph.D. at the University of Bologna. After spending about 10 years between the University of Geneva and the Sorbonne Université in Paris, I become researcher in 2010 and then research director in 2020 at the Enrico Fermi Research Center in Rome.  In 2025 I was awarded of the title of honorary professor at the Institute of Technology of Sumatra (Indonesia). My research activity includes statistical physics of complex astrophysical and cosmological systems, self-gravitating systems, galactic kinematics and dynamics. Beyond my professional publications, I am author of several books about the problem of higher education and academic research in Italy and abroad and more generally about science and politics. I write comments on several Italian dailies (mostlty on Il Fatto Quotidiano)
