Psalm 19 and Job 38 viewed through the lens of modern cosmology

Psalm 19 and Job 38, when viewed through the lens of modern cosmology, particularly the phenomenon of redshift, offer intriguing points of intersection between ancient poetic descriptions of the cosmos and contemporary scientific understanding. While these texts predate our modern understanding of redshift by millennia, their evocative language can be interpreted as accommodating, or at least not contradicting, the concept.

Psalm 19: A Universal Declaration

Psalm 19 begins with a powerful statement: "The heavens are telling of the glory of God; And their expanse is declaring the work of His hands." This verse emphasizes the vastness and communicative nature of the cosmos. In the context of redshift, we can see this "telling" as the light from distant galaxies, stretched and shifted towards the red end of the spectrum, carrying information about the universe's expansion.

"Day to day pours forth speech, And night to night reveals knowledge." This suggests a continuous flow of information from the heavens. Redshift, in essence, is a form of this "speech," providing scientists with data about the velocity and distance of celestial objects. The subtle shifts in light reveal knowledge about the universe's past, its expansion rate, and the distribution of matter.

The psalm's focus on the heavens' "expanse" aligns well with the concept of an expanding universe. Redshift is a direct consequence of this expansion, stretching the wavelengths of light as galaxies move further apart. Thus, the very "expanse" that the psalmist celebrates is the very phenomenon that makes redshift possible. The continuous communication from the heavens, as described, can be seen as the ongoing flow of redshifted light, revealing the dynamic nature of the cosmos.

Job 38: The Dwelling of Light and Darkness

Job 38, in which God addresses Job, delves into the mysteries of creation. "Where is the way to the dwelling of light? And darkness, where is its place, That you may take it to its territory And that you may discern the paths to its home?" These questions highlight the complexity and inscrutability of light and darkness.

In the context of redshift, "the dwelling of light" can be interpreted as the origin of light itself, the distant galaxies and quasars whose light is stretched as it travels to us. The question of "the way" to this dwelling can be seen as a reference to the vast distances light travels, and the changes it undergoes in the process. Redshift is a key component of understanding these "paths" to light's home, as it allows us to map the universe and determine the distances to these sources.

The mention of "darkness" alongside light is also significant. Redshift reveals not only the movement of luminous objects but also the vast, dark spaces between them. The stretching of light into the infrared and beyond means that much of the universe's light is shifted out of the visible spectrum, contributing to the "darkness" of the cosmos. Job's questions about the territories of light and darkness can be seen as a recognition of the intricate interplay between these phenomena, a balance that redshift helps us to understand.

Furthermore, the idea of discerning "paths to its home" can be linked to the concept of cosmological redshift as a tool for tracing the history of the universe. By measuring the redshift of distant galaxies, scientists can determine their velocities and distances, effectively mapping the "paths" that light has taken to reach us. This allows us to reconstruct the universe's expansion history and gain insights into its origins.

Accommodation, Not Direct Prediction

It's crucial to emphasize that these verses do not directly predict redshift. Rather, their poetic and metaphorical language allows for interpretations that are consistent with our current understanding of the universe. The verses speak to the vastness, dynamism, and informational richness of the cosmos, qualities that redshift helps to reveal.

The ancient authors of these texts were not privy to the scientific details of redshift. However, their profound observations of the heavens and their questions about the nature of light and darkness reflect a deep curiosity about the universe. This curiosity, in a sense, aligns with the scientific drive to explore and understand the cosmos, a drive that has led to the discovery of redshift and its implications.

In conclusion, while Psalm 19 and Job 38 do not explicitly mention redshift, their evocative language and profound questions about the heavens can be interpreted as accommodating this scientific phenomenon. They speak to the vastness, dynamism, and informational richness of the cosmos, qualities that redshift helps to reveal. By viewing these ancient texts through the lens of modern cosmology, we can appreciate the enduring power of their poetic insights and the ongoing quest to understand the universe.
