The concept of isotropy refers to the idea that space has no preferred direction—every point in space is equivalent, and the universe looks the same in all directions. This was a modern discovery in cosmology, but it was subtly alluded to in the Quran 1400 years ago.

Isotropy, in cosmology, means that the universe does not have a center or preferred direction. No matter where you look in space, the universe appears uniform and isotropic, without any directional bias.

In Quran 24:35, it describes Allah as the Light of the heavens and the earth. A part of this verse is as follows:

This phrase, "neither eastern nor western", suggests the absence of any preferred direction in space, implying a uniformity in all directions. The metaphor of light, which illuminates equally from all sides, serves as an analogy for the idea that space itself has no specific orientation or center—there is no "eastern" or "western" bias in the universe.

Today, cosmologists confirm that the universe is isotropic at large scales. The Cosmic Microwave Background (CMB) radiation, which provides a snapshot of the early universe, is remarkably uniform in all directions, showing no preferred center or direction. The Quranic reference, made in the context of an allegory about divine light, seems to coincide with this modern understanding, emphasizing the lack of directional preference in space. This was a concept unknown to humanity at the time of the Quran’s revelation.

While ancient cosmologies often placed the Earth or a central point as the focal point of the universe, the Quran, in verse 24:35, subtly hints at the concept of isotropy—no preferred directions in space. This was later confirmed by modern cosmology, showing a remarkable alignment between Quran and contemporary scientific understanding. 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.
