Rainbows and the Firmament

I’ve discussed previously the possibility that the earth may have dome-like Firmament over it as is described in the Bible and other ancient myths. The other day I saw a rainbow and figured whether its existence is evidence of a glass-like dome over our world.

A light that shines through a prism can create the colours of a rainbow, and a thick enough piece of glass can act as a prism. This can happen also accidentally if a glass door or other glass structure is hit by a beam of light. How about the rainbow then? Could it be created through a similar process? Is there glass in the sky?


The difference between a rainbow and a light shone though glass is that a rainbow is shaped like a bow, whereas light refracted with a prism tends to be straight. However, it’s probably due to the shape of most prisms. There’s a video on Youtube where someone has created round rainbow colours with CDs. So if there is glass in the sky, it seems to be circular, or dome like.

Another thing is that although natural rainbows are pretty big, they’re nowhere near as big as the earth, i.e. a rainbow cannot represent a dome that covers the entire earth. They only cover a small portion of it.

If the Firmament does exist, then maybe the dome is not like  a snowglobe, but a like an egg carton with several small domes interconnected.



Although I think the egg carton idea sounds silly. There’s another possibility; the Bible refers to “windows of heaven” opening several times. Let’s assume again that there is a glass-like Firmament up there, then there could be windows or other kinds of hatches that open from time to time. Perhaps rainbows are formed when sunlight hits the edge of a window in the glass dome as it is open.

In Norse mythology there is Bifröst, the rainbow bridge that grants passage between Midgard, earth, and Åsgard, the realm of gods. If the Firmament exists, and one wishes to leave earth to the heavens, what we call outer space, they’d have to get through the Firmament first. If there are windows in the Firmament, and opening such a window would, at least on some occasions, create a rainbow, then it would make sense why the Norse thought that the rainbow bridge can lead people into the heavens.

I am just putting out a theory, not saying this is necessarily true, but I see the existence of rainbows as possible evidence of the Firmament existing. It might simply be that the modern science explanation for rainbows is correct: “A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured arc.” Yet I don’t get why would the rainbow be shaped like an arc?

I’ll add the compulsory disclaimer that I am not a Christian, yet recently I find myself being drawn to the Bible for answers more often than what is called science. Take it for what its worth.
