1400 years ago, the concept of redshifting—where light from distant galaxies shifts toward the red end of the spectrum due to the expansion of the universe—was unknown. Today, we understand that as the universe expands, light waves stretch, making distant objects appear redder.

In Quran 55:37, God describes the sky as splitting open like a rose: "If the heaven ripped and it were a rose like paint." This metaphor beautifully captures the concept of universal expansion. Just like a rose's petals move outward at varying speeds, galaxies move apart, with those farther away receding faster, causing a redshift in the light we see from them.

When galaxies recede from us, the light they emit stretches, causing it to shift toward the red end of the spectrum. This effect is analogous to how a sound's pitch changes as it moves toward or away from you. This is also how the color of light changes depending on whether the light source is approaching (blue shift) or receding (redshift). The faster a galaxy moves away, the more pronounced its redshift.

The Quran's description of the sky splitting like a rose not only captures the idea of galaxies moving apart but also reflects the varying degree of redshift with distance. The farther a galaxy is, the more its light shifts toward red, much like the uneven application of paint on a surface. The Quran's accurate description of this phenomenon, long before it was understood, highlights its miraculous nature. This understanding of the universe expanding and the redshift of light aligns with modern astrophysics, reaffirming the Quran's miraculous knowledge. Crucially, whilst these verses might not necessarily reference the scientific findings mentioned here, they showcase how, even the most hard to imagine realities explained by the Quran, can be shown to be permissible with modern scientific discoveries.
