The Nature of Time, Block Time, and Retrocausality in a Christian Theological Framework

 



1. IntroductionTime is a fundamental aspect of human experience, yet its nature remains elusive. In physics, the block universe model, derived from Einstein’s theory of relativity, suggests that all moments—past, present, and future—are equally real in a four-dimensional spacetime continuum. This view contrasts with the intuitive, linear progression of time and raises profound questions for Christian theology, which posits a God who is both transcendent and immanent, existing outside time yet acting within it. Biblical passages such as 2 Timothy 1:9, which speaks of God’s purpose “before the ages began,” and Revelation 1:8 and 22:13, where God is described as the “Alpha and Omega” and the “first and last,” provide a theological lens for understanding God’s relationship to time. This article explores the block universe, retrocausality, and the Andromeda Paradox, examining whether divine intervention could alter events in a fixed spacetime block, particularly in light of Christian eschatology and divine omnipotence.
The concept of time has evolved significantly across intellectual history, shaped by philosophy, science, and theology. Ancient thinkers like Aristotle viewed time as a measure of change, tied to motion and events, while Augustine of Hippo framed it as a subjective experience within the human mind, distinct from God’s eternal present. The scientific revolution, particularly Newton’s absolute time, treated time as a linear, universal framework, flowing uniformly regardless of events. Einstein’s relativity revolutionized this view, introducing spacetime as a four-dimensional continuum where time is relative to observers, as seen in phenomena like time dilation. The block universe model, emerging from relativity, posits that past, present, and future coexist, yet humans perceive time moving forward due to psychological and thermodynamic factors. Our sense of time’s forward arrow is driven by the second law of thermodynamics, where entropy increases, creating an asymmetry between past (low entropy) and future (high entropy). Psychologically, memory formation and conscious experience are oriented toward accumulating past events, reinforcing the subjective perception of time’s unidirectional flow, even in a static block universe.

Here is what Stephen Hawking said about time in his book " A Brief History of Time":

  • On the Nature of Time and Relativity:
    • “The theory of relativity gets rid of absolute time. Consider a pair of twins. Suppose that one twin goes to live on top of a mountain while the other stays at sea level. The first twin would age faster than the second. Thus, if they met again, one would be older than the other. In this case, the difference in ages would be very small, but it would be much larger if one of the twins went for a long trip in a spaceship at nearly the speed of light.” (Chapter 2)
    • This quote highlights how Einstein’s relativity eliminates a universal, absolute time, showing time as relative to motion and gravity, a key idea in understanding the block universe.
  • On the Arrow of Time:
    • “The increase of disorder or entropy with time is one example of what is called an arrow of time, something that distinguishes the past from the future, giving a direction to time.” (Chapter 9)
    • Hawking explains the thermodynamic arrow of time, where entropy’s increase drives our perception of time moving forward, aligning with your question about why we feel time’s progression.
  • On Time’s Beginning:
    • “As far as we are concerned, the universe might as well have started at the big bang, since we cannot observe any events before it. The question of whether the universe really had a beginning in time or whether it just seems that way because of the way we observe it is a matter for philosophy and metaphysics.” (Chapter 8)
    • This reflects Hawking’s discussion of time’s origin at the Big Bang, resonating with  reference to 2 Timothy 1:9 about a state “before time began.”
  • On Imaginary Time and the Universe:
    • “One could think of ordinary, real time as a horizontal line, going from left to right. By contrast, another kind of time, which one might call imaginary time, would go in a vertical direction. In this sense, imaginary time could be thought of as a direction at right angles to ordinary time.” (Chapter 8)
    • Hawking introduces the concept of imaginary time to describe a universe without boundaries, offering a perspective that could connect to theological ideas of God’s transcendence over linear time.
  • On Time and the Universe’s Structure:
    • “The universe is not expanding in a previously existing space; space itself is expanding, and it carries the galaxies with it. Similarly, one cannot talk about time before the big bang, because time, like space, was created at the big bang.” (Chapter 3)
    • This underscores the idea that time is a property of the universe, created at its origin, which aligns with the theological notion of God existing “before the ages began” (2 Timothy 1:9).
  • “However, if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason—for then we would know the mind of God.”
  • 2. The Nature of Time and the Block UniverseThe block universe model emerges from Einstein’s special and general relativity, which describe spacetime as a four-dimensional manifold where time is a dimension analogous to space. In this model, all events—past, present, and future—coexist as fixed points in a single, unchanging block. This view aligns with the “eternalism” of philosopher J.M.E. McTaggart, who argued that time is a static dimension rather than a dynamic flow (McTaggart, 1908). Our perception of time’s passage is merely our consciousness moving through this block, experiencing events sequentially.
    Theologically, the block universe poses challenges. If all events are fixed, how can free will, divine intervention, or eschatological fulfillment operate? Christian theology traditionally holds that God is eternal, transcending time yet acting within it. 2 Timothy 1:9 states that God’s grace was given “in Christ Jesus before the ages began” (ESV), implying a state of divine existence prior to the creation of time itself. This suggests that God operates outside the temporal framework, potentially viewing the block universe as a whole and interacting with it in ways that transcend human perception.
    3. Biblical Perspectives on Time and God’s EternityChristian theology offers a rich framework for understanding time through biblical texts. Revelation 1:8 declares, “I am the Alpha and the Omega,” says the Lord God, “who is and who was and who is to come, the Almighty” (ESV). Here, God is described as the arche (beginning) and telos (end), encompassing all of time. This suggests a divine perspective that transcends the linear progression of human experience, aligning with the block universe’s static nature. However, Revelation 22:13 modifies this language, stating, “I am the Alpha and the Omega, the first and the last, the beginning and the end” (ESV), introducing protos (first) and eschatos (last). The shift from telos to eschatos emphasizes eschatological finality, suggesting that God not only initiates creation but also brings it to its ultimate conclusion.
    These passages imply that God exists outside the block universe, with the ability to act across all points of spacetime simultaneously. The reference in 2 Timothy 1:9 to “before the ages began” further supports this, indicating a pre-temporal divine state. If God created time, then the block universe itself is a product of divine will, potentially designed with flexibility for divine action, even if it appears fixed from a human perspective.
    4. Retrocausality: A Mechanism for Divine Action?Retrocausality, the idea that future events can influence the past, emerges from quantum mechanics and offers a potential framework for understanding divine intervention in a block universe. In quantum experiments, such as Wheeler’s delayed-choice experiment, measurements made in the present appear to retroactively determine the behavior of particles in the past (Wheeler, 1978). The transactional interpretation of quantum mechanics, proposed by John Cramer, posits that quantum events involve “offer waves” moving forward in time and “confirmation waves” moving backward, creating a handshake across time (Cramer, 1986).In a theological context, retrocausality could provide a mechanism for divine intervention. If God exists outside time, as suggested by 2 Timothy 1:9, divine actions could manifest as retrocausal influences, shaping past events from a future perspective. For example, a miracle in the past (e.g., the resurrection of Jesus) could be seen as a divine act initiated from a future eschatological perspective, embedded in the block universe’s structure. This aligns with the concept of God creating “from the future backward,” where the telos or eschatos of Revelation shapes prior events to fulfill divine purpose.
    However, retrocausality raises philosophical challenges. If future events influence the past, does this undermine free will or create paradoxes? In a block universe, such paradoxes may be resolved, as all events are fixed and consistent within the block. Divine retrocausal action could be seen as part of the block’s design, ensuring that interventions align with God’s eternal plan without disrupting the coherence of spacetime.
    5. The Andromeda Paradox and Relativity of SimultaneityThe Andromeda Paradox, a thought experiment derived from special relativity, illustrates the relativity of simultaneity and its implications for the block universe. Imagine two observers on Earth, one stationary and one moving rapidly toward the Andromeda Galaxy. Due to relativistic effects, their “now slices” (the set of events they consider simultaneous) differ. The moving observer’s “now” includes events in Andromeda that the stationary observer considers future (Penrose, 1989). For example, if an alien in Andromeda is deciding to invade Earth, the moving observer might perceive this decision as already made, while the stationary observer sees it as yet to occur.
    This paradox highlights that the block universe contains all events, but human perception of “now” is relative. Theologically, this raises questions about divine simultaneity. If God is the “Alpha and Omega” (Revelation 1:8), God perceives all events in the block simultaneously, transcending the relativity of human observers. The Andromeda Paradox suggests that what we perceive as future events (e.g., eschatological fulfillment) are already real in the block, accessible to God’s eternal perspective. Divine intervention could thus involve God acting on these “future” events, which, from a human perspective, appear as changes to the block.
    6. Divine Intervention in a Block UniverseThe possibility of divine intervention in a block universe is a central theological concern. If the block is fixed, how can God alter events? Several possibilities emerge:
    1. Embedded Interventions: The block universe may include divine interventions as part of its structure. From God’s perspective, miracles or divine acts are not alterations but inherent features of the block, designed “before the ages began” (2 Timothy 1:9). Human perception of change reflects our limited, sequential experience of the block.
    2. Retrocausal Divine Action: Retrocausality offers a mechanism for divine intervention. God, existing outside time, could influence past events from a future vantage, ensuring that the block aligns with divine purpose. For example, the eschatos of Revelation 22:13 (the final state of creation) could retrocausally shape earlier events, such as the calling of the apostles or the exodus.
    3. Multiple Timelines: Some interpretations of the block universe, inspired by quantum mechanics’ many-worlds hypothesis, suggest that the block contains all possible outcomes. Divine intervention could involve guiding which timeline is actualized, preserving free will while fulfilling divine will.
    4. Transcendent Action: As the “Alpha and Omega,” God may transcend the block entirely, interacting with it in ways that defy human understanding of causality. This aligns with the theological view that God’s omnipotence allows for actions that appear miraculous within time but are coherent from an eternal perspective.
    These possibilities reconcile the fixity of the block universe with divine freedom, suggesting that God’s actions are not constrained by human perceptions of time.
    7. Theological Implications: Eschatology and Free WillThe interplay of block time, retrocausality, and divine intervention has profound implications for Christian eschatology and free will. Revelation 22:13’s emphasis on God as the protos and eschatos underscores an eschatological framework where the end shapes the beginning. If God creates from the future backward, as suggested by retrocausal models, the final state of creation (e.g., the new heavens and new earth) could influence prior events, ensuring that history aligns with divine purpose.
    This raises questions about free will. In a block universe, human choices appear fixed, yet Christian theology affirms human responsibility. One resolution is that the block includes all possible choices, and divine intervention guides which possibilities are realized without negating freedom. Alternatively, retrocausal divine action could subtly shape human decisions, preserving the illusion of freedom while aligning with God’s plan.
    8. ConclusionThe block universe, retrocausality, and the Andromeda Paradox offer a compelling framework for exploring the nature of time within a Christian theological context. Biblical texts like 2 Timothy 1:9, Revelation 1:8, and Revelation 22:13 portray God as transcending time, existing as the arche and telos, protos and eschatos. These passages suggest that God’s eternal perspective encompasses the entire block universe, allowing for divine intervention that may appear as retrocausal influence from a human perspective. The Andromeda Paradox illustrates the relativity of human temporality, reinforcing the idea that God’s simultaneity transcends our limitations.
    While the block universe implies a fixed spacetime, divine omnipotence and transcendence allow for interventions that are coherent within the block’s structure. Retrocausality provides a potential mechanism for such actions, aligning with the theological notion of God creating from the future backward. Ultimately, the Christian view of God as the “Alpha and Omega” offers a hopeful perspective: even in a fixed block, God’s eternal purpose ensures that all things work toward the eschatological fulfillment promised in Revelation.
