I only read the KJV.
I think the firmament may be be made out of a kind of aerogel. Aerogel can crumble but scientist have over come this problem.

Dear Sister, thank you for your creative thought!
I appreciate your curiosity and willingness to explore how science and Scripture might connect. It’s always refreshing to see people
thinking beyond the surface. That being said, I’d like to respond with both
spiritual discernment and
biblical clarity.
1. Let’s Be Clear on What the “Firmament” Actually Is
When Genesis 1 speaks of the
"firmament" (Hebrew: raqia), it’s referring to what separates the waters above from the waters below (Genesis 1:6–8). Later, it says God placed the
sun, moon, and stars in the firmament (v.14–17), and that birds fly “across the face of the firmament of the heavens” (v.20).
From these verses alone, we can understand this “firmament” isn’t a
substance like metal, crystal, or aerogel it’s
a space. A vast
expanse, which is why many modern translations use the word
“expanse” instead of “firmament.” It refers to the
sky, the
heavens, and the
cosmic order not a material object you can touch or analyze under a microscope.
2. Aerogel Is Fascinating but the Bible Isn’t a Physics Lab
Aerogel is indeed an impressive material light, porous, and translucent. But let’s not confuse modern
scientific materials with
ancient Hebrew cosmological metaphors.
If we claim that the firmament is made of
a physical substance like aerogel, we run into two big issues:
- We’re treating the Bible like it’s trying to explain modern material science, which it’s not.
- We reduce the glory of divine revelation to speculative physical theories that aren’t supported by the text.
God
never intended Genesis to be a chemistry class. He gave us Genesis 1 as a theological declaration:
He is Creator, He brings
order out of chaos, and He sets
boundaries for the cosmos. That’s the real miracle not aerogel.
3. Firmament Is Functional, Not Material
In the ancient Near Eastern world, including Israel’s culture, cosmological terms were understood
functionally in terms of
purpose, not
composition.
God separated, named, and gave purpose to the elements of creation:
- Light to rule the day.
- Lights to mark seasons and days.
- The firmament to separate and contain.
So the “raqia” is not a material dome or some exotic structure, but a
divinely ordained space a
cosmic boundary that reflects God’s order and sovereignty.
4. Let’s Not Drift from the Word to Speculation
Honorable Sister in Christ, I say this in love: we have to be
careful not to let our imaginations override what the Word actually says. Scripture tells us plainly what the firmament is for, let’s not stretch it into something speculative just because science offers an exciting material.
We’re not called to
merge the Bible with scientific guesswork, but to
rightly divide the Word of truth (2 Timothy 2:15). The beauty of the firmament isn’t
what it’s made of it’s
Who made it, and
why.
5.Let’s Marvel at the Creator, Not Just Creation
It’s okay to explore science. In fact,
science should lead us to deeper worship, not deeper speculation. But our foundation must always be the
unchanging Word of God.
As Psalm 19:1 declares:
“The heavens declare the glory of God; the skies proclaim the work of His hands.”
So whether God stretched the sky like a curtain (Isaiah 40:22), or called it “raqia,” the
focus is not the material, but the
majesty of the One who made it.
Let’s stand in awe, not of aerogel but of the God who
stretched out the heavens, who
names every star, and who sent His Son to redeem the world beneath them.
I hope this help you to understand deeply and if you have any question regarding this please let me know and the Holy Spirit will guide us to the revelation of the Word of God.
Grace and Blessings!
