From Eternity to Here.. The Quest for the Ultimate Theory of Time

Sean Carroll's From Eternity to Here examines the nature of time through the lens of modern physics, offering insights that bear significantly on cosmological arguments for God's existence. While primarily a work of popular science explaining entropy and the arrow of time, Carroll's analysis engages fundamental questions about the universe's origin and structure that traditionally intersect with theological discourse.

Carroll begins by addressing the profound asymmetry between past and future, grounding this distinction in the second law of thermodynamics. He argues that time's arrow emerges from the universe's low-entropy initial conditions at the Big Bang, a state requiring explanation. This discussion directly confronts cosmological arguments that invoke God as the necessary explanation for the universe's fine-tuning or initial conditions. Carroll suggests that physics itself may provide sufficient explanatory resources without recourse to supernatural causation.

The work's central contribution to the God debate lies in its treatment of ultimate origins. Carroll explores various cosmological models, including eternal inflation and quantum fluctuations, that potentially explain the universe's low-entropy beginning without invoking external design or causation. He argues that the universe need not have a beginning in any absolute sense, thereby challenging premise-based cosmological arguments that depend on the universe having a first moment requiring divine causation.

Methodologically, Carroll employs the explanatory frameworks of statistical mechanics, general relativity, and quantum field theory to address questions traditionally reserved for metaphysics. His approach exemplifies how modern physics reconceptualizes classical philosophical problems about time, causation, and cosmic origins. While maintaining scientific objectivity, Carroll implicitly challenges theistic explanations by demonstrating how physical laws might account for features of the universe that appear designed or purposeful.

The work engages particularly with fine-tuning arguments, suggesting that our universe's time-asymmetric properties might emerge naturally from more fundamental physical principles rather than divine selection. Carroll's multiverse considerations offer naturalistic alternatives to design hypotheses, though he acknowledges the speculative nature of such proposals.

Carroll's contribution reshapes the cosmological argument debate by updating it with contemporary physics, demonstrating how scientific advances continually transform the conceptual landscape within which arguments about God's existence operate. His work represents a significant naturalist response to modern cosmological arguments, illustrating how scientific explanation might extend to ultimate questions previously thought to require theological answers.
