Ceramah: Kosmos dan Masalah Kebebasan Tuhan

Summary

The lecture examines a question associated with Einstein: Does God have a choice when creating the universe? Karlina Supelli does not offer a final answer. Instead, she traces how cosmology, physics, and medieval debates about divine freedom have shaped the modern separation between science and theology.

Main Ideas

• Scientific facts can be easier to accept when they concern physical objects than when they challenge human self-understanding. The opening speaker contrasts the everyday comprehensibility of gravity and electricity with the resistance many people feel toward evolution or the idea that Earth is not cosmically special. This resistance may arise not only from religious belief but also from fear.

• Cosmology raises a problem of apparent fine-tuning. Some physical constants and conditions seem to fall within extremely narrow ranges that permit stars, planets, and life. The lecture discusses the number 137, presented as a striking constant in physics, and the broader puzzle of why the universe’s parameters have the values they do.

• The anthropic principle and multiverse proposals offer one response. If there are many universes with different properties, it may be unsurprising that observers find themselves in one compatible with life. But this raises a theological question: if the universe’s possible conditions are so tightly constrained, how free was God in creating it?

• A literary story illustrates a universe that is creative but not necessarily compassionate. Supelli recounts Olaf Stapledon’s Star Maker: a cosmic creator experiments with universes, some of which contain beauty and life but still end in destruction. The story’s creator is depicted less as morally good or evil than as an artist experimenting. C. S. Lewis objected to this outlook, seeing it as religiously damaging.

• The problem of God’s freedom has deep medieval roots. Aristotelian cosmology described a bounded, eternal universe, which seemed to place limits on divine power and conflicted with Christian ideas about creation and heaven. Medieval thinkers debated whether God’s power could be constrained by logic or by the laws of nature. The lecture refers to the Paris condemnations of Aristotelian propositions as part of this debate.

• Aquinas and Ockham represent different ways of handling the tension.

  • Aquinas sought to reconcile Aristotelian philosophy with Christian doctrine, expanding the cosmos in a way that made room for heaven while retaining a rationally ordered account of nature.
  • William of Ockham distinguished God’s absolute power (potentia Dei absoluta) from the orderly way God normally governs the world (potentia Dei ordinata). God could create or not create, and could act beyond the ordinary order.
  • Ockham’s approach also challenged the idea that universal laws and causal relations exist as things in the world in the same way particular things do. Such universals may be concepts formed by the mind. This nominalist approach helped separate philosophical investigation of nature from theology, while also leaving religious faith less open to rational criticism.

• The separation of nature from theology helped shape modern science. In the lecture’s account, nature came to be treated as a created mechanism governed by mathematical laws. Galileo’s idea that the “book of nature” is written in mathematics and Newtonian mechanics exemplify this shift. Francis Bacon added an emphasis on making knowledge practically effective. Science increasingly investigated the workings of the world without needing to invoke God in its explanations.

• Modern cosmology both extends knowledge and encounters limits. General relativity, quantum theory, and proposals such as string theory have not yet produced a settled account joining the very large and the very small. The early-universe singularity marks a point where current theories break down. Supelli presents this not as proof of God, but as a boundary of present knowledge; interpreting it as an epistemological limit leaves the question open.

• The lecture ends by accepting uncertainty rather than claiming a solution. Cosmology may describe the universe’s development, but it cannot by itself settle what God is or whether God is free. Supelli suggests that a “space of supposition”—imagination, poetry, and silence—can coexist with the disciplined claims of empirical science. She closes with a poem by George Herbert that uses the language of challenge, prayer, and “if” in addressing the divine.

Discussion and Audience Questions

• Can the large-scale universe and the microscopic world be unified? Supelli says this remains unresolved. General relativity describes gravity and the large-scale cosmos, while quantum theory describes the microscopic realm; combining them is a central challenge. String theory is one attempt. Until such a theory is established, the singularity remains beyond current explanation.

• Has human evolution reached a dead end? Supelli says there is no basis for a definite answer. Evolution unfolds over long periods through variation, mutation, and environmental change. Changes in organisms can be observed, but predicting a future human form is speculative.

• Could cosmology simply leave God out of the question? Supelli says that scientists can investigate nature without making God part of their working explanations. She illustrates this with Newton: he invoked God to account for the stability of the solar system, whereas Laplace later argued that his mathematical explanation did not need that hypothesis. Setting God aside can free scientific inquiry from theological assumptions, though it does not resolve theological questions.

• What are space and time? The discussion contrasts Newton’s conception of space and time as an enduring framework with Einstein’s account of spacetime, in which they are dimensions connected to physical events. String theory imagines additional dimensions, though these remain part of a mathematical framework rather than ordinary experience.

• Does science make the world less beautiful? Supelli disagrees with the idea that scientific explanation necessarily strips nature of its charm. Knowing how glaciers, caves, or other natural formations come about can reveal another kind of beauty rather than diminishing their visual appeal.
