1400 years ago, the concept of the equivalence principle—discovered by Einstein—was unknown. It states that gravity and acceleration have the same effects locally. In a gravitational field (like on Earth) and in an accelerating spacecraft, objects feel the same force pulling them down. This principle, crucial to general relativity, was confirmed by modern science but was remarkably foreshadowed in the Quran.

In Quran 55:7, God describes raising the sky and setting up the balance: "And the sky, He raised; and He set up the balance." The "raising the sky" implies an accelerating frame of reference, while the "balance" refers to mass balance—something that works only in gravitational or accelerated conditions. This understanding aligns with the scientific equivalence principle, which says mass balance functions under both gravity and acceleration.

Einstein’s equivalence principle shows that the effects of gravity and acceleration are locally indistinguishable. For example, in an accelerating spacecraft or on Earth, objects feel a downward force. However, in zero gravity, mass balances don’t work, as there’s no force acting on the objects.

The Quranic reference to both gravity and acceleration in one verse parallels the equivalence principle, which was unknown at the time. This highlights the miraculous nature of the Quran’s knowledge, further confirming its divine origin. 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.
