It is true that the ancients lacked the scientific instruments and mathematical equations we possess today. This does not mean they were ignorant of any knowledge we now possess about the Universe.
In certain medieval writings there is a discussion of transparent “spheres” in outer space that seems at first glance to be nonsensical false science.
Certain Biblical statements, although written in simple language that could be understood by people of all ages, can be interpreted to shed light on certain scientific mysteries that exist to this day.
In Maimonides’ book “Guide to the Perplexed” (12th century C.E.), he identifies the Hebrew word “rakia” in Genesis (translated as “firmament”), as what modern science might call the spherical dark matter halo.
Maimonides cites the Biblical verse “And God set them (the stars and planets) in the firmament” (Genesis 1:17) to explain that “all the stars as well as the sun and the moon are situated within the sphere, as there is no vacuum in the world, and they are not located on the surface of a sphere as the vulgar imagine.” In modern terms, Maimonides is explaining that the stars and planets are embedded in a transparent sphere of dark matter.
This ancient idea of spheres of dark matter is confirmed by modern science:
“The visible disk of the Milky Way Galaxy is thought to be embedded in a much larger, roughly spherical halo of dark matter.”

We ignore the great wisdom of the Bible and the great reasoning power of the ancients at our own peril. Contemporary scientists would have us believe that they have discovered information about the physical Universe that was never known to the ancients. That assumption is based on a certain modern arrogance and is incorrect.
