Paolo Beltrame SJ was born in 1976 in Rome, Italy. After high school with the Salesians, Beltrame studied particle physics at Rome’s La Sapienza University (one of his professors was Nicola Cabibbo, known for his contribution to the quarks model with the «Cabibbo angle»). Beltrame graduated with a master’s degree in physics in October 2004, after also obtaining a bachelor’s degree in philosophy at the Salesian Pontifical University.
His main interests focus on high energy physics, particle physics and cosmology, especially in what is commonly called the «dark sector» of the universe.
In early 2005, Beltrame was admitted to the Ph.D. course in particle physics at the Karlsruhe Institute of Technology, working on the phenomenology and measurement of the muon magnetic moment anomaly known as g-2. In 2009, he received his PhD in Particle Physics. In the same year, he moved to Geneva to work at CERN, collaborating on the LHC (Large Hadron Collider) experiments that led to the discovery of the Higgs Boson in 2012.
Having developed an interest in astrophysics and dark matter, he moved to the USA, to Los Angeles, with a post-doctoral contract to work there for two years. During this stay, he developed a theoretical model that hypothesized dark matter as consisting also of lighter particles than those most studied, called «axion-like» particles, the existence of which could also explain several phenomena in high-energy physics. Statistical models used to analyze experimental data have also been of great interest to Beltrame, even encroaching on more epistemological issues from fundamental research. This path then led him to collaborate with the Weizmann Institute of Science in Rehovot, Israel, where he moved in 2013. At the end of the same year, he was offered a faculty position at the University of Edinburgh to work specifically on axions and new models of statistical analysis, which also led him to work more closely with the Faculty of Philosophy at the same university. Let us recall that Edinburgh has seen Max Born, one of the fathers of Quantum Mechanics, and Peter Higgs as eminent figures on its staff.
In 2014 he met the Jesuits of the Lauriston Centre in the Scottish capital and in 2017 joined the British Province of the Society of Jesus, beginning his novitiate in Birmingham, where he professed vows in September 2019. Immediately afterwards, Beltrame moved to Paris to study theology at the Centre Sèvres, where he obtained a bachelor’s degree in theology, discussing the concept of creation according to the Dominican tradition of St Thomas Aquinas and the Franciscan tradition of St Bonaventure, also in the light of the latter’s «panentheistic» perspective, and of Jürgen Moltmann and Pierre Teilhard de Chardin. Panentheism interprets God as both immanent and transcendent in creation, and the cosmos not as a reality external to the Creator but rather as an entity contained within the divine womb. Since September 2022, Beltrame has been assigned for his regency two years of postdoctoral research at the Vatican Observatory in Tucson and at the University of Arizona Tucson to work at the Arizona Cosmology Lab.
The universe that we can observe, even with the most powerful telescopes available to us, constitutes about 5% of everything that exists in the cosmos, the remaining 95% being part of what we call the «dark sector» of the universe, of which about 68% is dark energy and 27% dark matter. Now, if we were asked what dark matter is, our most honest answer would have to be: we don’t know. However, we know very well what it is not. It is not normal matter, which we can observe, because it neither emits nor absorbs electromagnetic radiation (otherwise known as light), and it very rarely interacts with the normal atoms of which we are made. Even more enigmatic is dark energy, which is responsible for the accelerated expansion of the universe and which Einstein himself, the first to introduce it under the name of the «cosmological constant», described as his greatest mistake.
Trying to shed some light on these two immense mysteries concerning the cosmos – from its origin to the present day – is an exciting journey that will necessarily lead us to discover an ever more surprising God.
