The cited passage

What current science says

There is no solid dome over the Earth. The atmosphere is a gradient of gases that thins exponentially with altitude — sea-level air pressure is about 101 kPa, but by 100 km up (the Kármán line, where 'space' begins), it's essentially zero. Beyond that is the vacuum of space. The concept of a 'firmament' comes from ancient Near Eastern cosmology shared by Babylonians, Egyptians, and Hebrews, who all imagined a solid sky-dome holding back cosmic waters. We've launched over 6,000 rockets through the sky. Not one has bumped into a ceiling.

What the text says

This comes from Psalms 150:1. 'Praise him in the firmament of his power' — yet another reference to the solid dome that ancient Hebrews believed separated the waters above from the waters below.
