Is the belief that the sky is space and not a solid body considered disbelief, and what is the correct interpretation of the Quranic verses that describe the sky, and how can these verses be reconciled with modern scientific knowledge?

The difference between scientific theories and facts is fundamental. Theories are numerous and mutable, whereas facts are few and constant. Scientists' conception of the shape of the universe and the heavens has evolved, leading to discussions of the heaven as a cohesive, tightly constructed edifice, not a void. Scientists have spoken of the universe's matter and fabric, with galaxies forming its building blocks, and dark matter holding the galaxies together in a precise geometric system. The discourse about the heaven as mere space has been superseded by modern science, and science is still in its infancy regarding the details of cosmic construction. The term "heaven" refers to everything above us, part of which is air or space, and what lies beyond that is exceedingly complex. Scientists discuss this in terms of hypotheses, as humans are still incapable of grasping and proving scientific truth.
