This is a concise but marvelously rich statement about reality.
The reference to quantum entanglement is suggestive, but could be put more strongly. It is not simply that the reality disclosed by physics is more than a playing-out of deterministic principles. Einstein and Bohr famously argued about whether "quantum uncertainty" was real (Bohr's view) or simply a reflection of our lack of knowledge (Einstein's view). About ten years after Einstein's death a proof was given that a universe as Einstein envisioned might exist, but was not the universe that we live in.
Einstein was concerned about the intellibility of the universe, and his "lack of knowledge" assumption preserved intelligibility. But Bell's Inequality (and it's proof that Einstein's assumption does not fit our universe) does not mean that the universe is unintelligible, just that it's intelligibility is not consistent with Einstein's assumption.
Conventional theology is not bothered by a deterministic universe because God can act upon such a universe, from the outside, as it were. This requires a dualistic view of reality (e.g. this life, and then a next life if we qualify by being good). Those who reject God as a hypothesis view such intervention as impossible.
The creative addition provided by this article is that the evidence of quantum entanglement (which disproves a deterministic universe) is consistent with a single reality (not a dual this life and next life) within which we live and love. "Some form of survival that love makes possible" is a beautiful expression, within the limits of what we know.
Furthermore, while there are those who argue that the evidence of how "desperately we, the living, want to believe in this possibility" shows some form of wishful thinking, the article places this evidence in a context consistent with a different possibility, namely, that this evidence is an expression borne of our presence now in this single and fuller reality. It is the fuller reality which is enabled by love, and which persists notwithstanding death for those who love.
