  1. 1. Astrobiology: Resolution of the Statistical Drake Equation by Maccone's Lognormal Method in 50 Steps
    Dr Eugenio Mieli

    We use the mathematical tool of Maccone's lognormal distribution to further factor the Drake equation, which calculates the number of advanced civilizations in the galaxy, from the seven original levels of the Drake equation to 49 levels of overall analysis. The Maccone approach, in fact, supported by the central limit theorem, becomes more reliable the more levels are introduced. The...

  2. 8. Big History in Italy
    Prof. Adalberto Codetta (OPPI)

    Throughout history, different cultures have sought to weave a coherent tapestry of the universe and its evolution, driven by an innate curiosity about its origins. These narratives not only shaped cultural identities but often served as tools for asserting dominance. In the modern era, scientific endeavours took a pivotal turn with the discovery of cosmic background radiation in 1964,...

  3. 3. Il SETI in Italia: Una Storia Ancora da Scrivere
    Lorenzo De Piccoli

    L'Italia è stata uno dei paesi maggiormente coinvolti nelle ricerche SETI fin dagli albori di tale programma di ricerca; ricercatori e scienziati afferenti a istituzioni scientifiche come l'Istituto Nazionale di Astrofisica hanno contribuito significativamente alla ricerca internazionale. Tuttavia, non esiste ancora alcuno studio compiuto che tracci la storia dei progetti SETI condotti in...

  4. 4. On the Wormhole-Warp Drive Correspondence
    Kirill Zatrimaylov (Università degli Studi di Bergamo)

    We propose a correspondence between the Morris-Thorne wormhole metric and a warp drive metric, which generalizes an earlier result by H. Ellis regarding the Schwarzschild black hole metric and makes it possible to embed a warp drive in a wormhole background. We demonstrate that in order to do that, one needs to generalize the Natario--Alcubierre definition of warp drive and introduce nonzero...

  5. 5. Solitude or cosmic multitude in the Fermi Paradox and a complex approach to the Great Silence
    Maria Antonia Delli Gatti (University of Naples Federico II)

    Many explanations have tried to resolve the Fermi Paradox, some of which have argued for our cosmic solitude. The more sceptical positions emphasise the innumerable random factors in the emergence of living species, the contingent events that may determine their extinction, the rare conditions of our solar system or our planet. On the other hand, some scholars have argued the abundance of life...

  6. 7. TEMNO: Rilevamento e discriminazione di segnali astronomici transitori attraverso osservatori nanosatellitari
    Davide Negretti (POLIMI - DAER)

    Descriviamo il concetto di TEMNO - Transient Event Multimessenger Nanosat Observatory - un osservatorio spaziale compatto per l'astronomia degli eventi transitori. Sebbene sia piccolo ed economico, TEMNO offre una rilevazione wFoV efficace e scalabile, cueing e analisi di un'ampia gamma di segnali astronomici transitori - Gamma Ray Bursts (GRB), Fast Radio Bursts (FRBs), Supernovae (Sn)....
