This may sound like pantheism, but I think that it may answer one problem in  people’s belief in God.  I’ve long been bothered by a nagging question, “How could we communicate with God in prayer, if He is somewhere else in the vast universe.”  If the universe is as old as 16 billion years, or thereabouts, as scientists believe, and I believe, how could we get an answer to prayer in a lifetime?  And yet, I feel certain that I have had answers to prayer in a few minutes or a few days, or after a year or two.  The thing that occurred to me, is that God must have set the universe in motion at the Big Bang, and, as infinite as He must be, some of him would be available in every molecule of the universe, which was once the size of a mustard seed, according to George L. Schroeder: Ref. 1
        “The big bang produced from nothing, a universe composed of photons, energy packed radiations, unimaginably hot and compressed beyond description, a soup of energy, nearly homogeneous throughout.  (What produced the big bang remains a question.)  The universe was born as an undifferentiated unity, the oneness science struggles so to rediscover today.  But that unity was locked into the ultimate of black holes, a highly compressed mass, so dense with such a huge pull of gravity that nothing, not even something as ethereal as light, could escape.”
    My take on that, and don’t blame it on Dr. Schroeder, is that some of God could be in every particle of the universe.  Surely there must be enough to go around.  Then, as the universe expanded from a mustard seed size, and the energy became mass, by the relation, inverted from E = mc 2 to the form m = E/c 2,  part of God could have gone along with the expanding universe at the finite velocity at which it expanded.  Then, as we were born, each of us had billions and billions of these spirit-filled molecules, just waiting for us to believe.  Then, when we prayed, it would take very little time for it to reach the maker of the universe!   In another part of the book referred to above, Dr. Schroeder writes: Ref. 2
    “Within the brain we perceive the consciousness of the mind, and via the mind we can touch a consciousness that pervades the universe.  At those treasured moments our individual self dissolves into an eternal unity within which our universe is embedded.  That is the message both of physics and metaphysics.”

    Dr. Schroeder is the author of Genesis and the Big Bang (1990),  The Science of God (1997), The Hidden Face of God (2001), and God According to God (2009).  He earned his PhD at the Massachusetts Institute of Technology before moving to laboratories at the Weizmann Institute, the Hebrew University, and the Volcani Research Institute in Israel.  He lives in Jerusalem with his wife and their five children.
