Believe it or not, a Roman Catholic priest first proposed the Big Bang theory of the origin of the universe. In 1927, Georges Lemaître, a Belgian priest, astronomer, and physics professor, suggested that the expanding universe might be traced back to a single point of origin, a singularity. As Ilia Delio describes, “[It] appeared like a little quantum size blip on the screen [creatio ex nihilo] and inflated rapidly like a balloon and since that time, it has been expanding.”  I’ll let Delio, a scientist, explain the implications for this cosmology—our story of the universe:
Every human person desires to love and to be loved, to belong to another, because we come from another. We are born social and relational. We yearn to belong, to be part of a larger whole that includes not only friends and family but neighbors, community, trees, flowers, sun, Earth, stars. We are born of nature and are part of nature; that is, we are born into a web of life and are part of a web of life. We cannot know what this means, however, without seeing ourselves within the story of the Big Bang universe. Human life must be traced back to the time when life was deeply one, a Singularity, whereby the intensity of mass-energy exploded into consciousness. Deep in our DNA we belong to the stars, the trees, and the galaxies.
Deep within we long for unity because, at the most fundamental level, we are already one. We belong to one another because we have the same source of love; the love that flows through the trees is the same love that flows through my being
