Faced with the mystery of dark matter, which is thought to compose 85% of the mass of the universe, some renowned scientists draw their inspiration from an approach of faith or spirituality. This quest, which touches on the origins and destiny of the cosmos, sparks profound reflections where science and faith, far from being opposed, can reveal themselves to be complementary.
Dark matter, whose existence is only inferred by its gravitational effects on visible matter, remains one of the greatest scientific enigmas of our time, alongside dark energy which accelerates the expansion of the universe. This invisible reality, described by physicists as a kind of "cosmic glue" structuring galaxies, leads researchers to explore unexpected paths.
This is the case for Chanda Prescod-Weinstein, an astrophysicist who, although defining herself as agnostic-atheist, draws inspiration from Jewish teaching and the Torah. She recounts being encouraged in her research on a theoretical particle, the axion, by Vera Rubin, the astronomer whose work in the 1970s provided the first solid evidence for the existence of dark matter. According to her, the narratives of the Torah describe an intimate relationship of humanity with the night sky, perceived as an integral part of Creation, a perspective that nourishes her scientific approach.
Brittany Kamai, the second Native Hawaiian to earn a doctorate in astrophysics, also turned to her spiritual roots to confront these questions. After contributing to the development of high-tech instruments at Fermilab, she committed to learning ancestral celestial navigation, without modern instruments. For her, this spiritual approach, often overlooked by scientists, could hold a key. "Physics boils down to a set of waves," she explains, wondering if a deeper connection with the universe, from the depths of the ocean, could not illuminate the mystery of dark energy.
Researcher Doug Watson, for his part, found new inspiration in Hinduism. Faced with doubt and professional burnout, he discovered within the Hare Krishna movement a tradition that encouraged scientific curiosity. In the sacred texts, he perceived narratives that, while not scientific facts, seemed to him to present inspiring parallels with concepts like the observer effect in quantum mechanics. "I don't think we should draw direct lines between religious texts and scientific facts," he clarifies, but he sees in these stories a source of inspiration for "new ways of thinking about the origins of the universe."
This convergence is not without its critics. Astrobiologist Adam Frank, a Zen Buddhist, warns against the risk of basing one's faith on constantly evolving scientific theories. For him, the true link lies in the sense of wonder common to science and spirituality.
From this perspective, Father Adam Hincks, a Jesuit priest and auxiliary member of the Vatican Observatory, believes that the contemplation of dark matter can, for some, elevate the spirit towards God, just as the contemplation of a work of nature does. "As creator, God is present in all of creation, and contemplating creation is a portal to contemplating the divine," he affirms.
Ken Freeman, an Australian astrophysicist and pioneer in dark matter research, ponders the role of intuition in scientific discovery. As a Christian, he confides: "You wake up in the middle of the night with a thought and you have no idea where it came from. Believers might see the action of the Holy Spirit." Regarding his own engagement in this field, he admits that this possibility, while not a certainty, remains "a nagging question."
Jennifer Wiseman, a Christian astrophysicist, emphasizes for her part that the study of the universe, far from making us insignificant, can strengthen our sense of unity. According to her, these contemplations should inspire "joy, humility, and love," reminding us of our common condition on the same planet.
