Critics argue that descriptions of the sky being "stretched" in Jeremiah 10:12 ("...and hath stretched out the heavens by his discretion") imply a physical, solid dome of some sort.

Actually, it is not possible to determine this from the text alone, for the Hebrews (like many cultures of this time) lacked a word-concept of infinite physical space. With that in mind, we may ask how they would describe the sky as it exists, and metaphor is the most probable choice. We surmise that describing the sky as a "stretched" space or object comes as close to capturing "infinity" as one can without the precise word-concept.
