“Thus saith the LORD, thy redeemer, and he that formed thee from the womb, I am the LORD that maketh all things; that stretcheth forth the heavens alone; that spreadeth abroad the earth by myself” (Isaiah 44:24 KJV). Scriptural texts like this have been used by biblical creationists to justify God creating an expanding cosmos. Aside from arguing that the Scriptures do indeed describe cosmological expansion, I contend that expansion of space is of itself not tenable as a mechanism for the expansion of the universe, as often cited with the famous rubber balloon analogy. Relativity theory, properly applied, tells us that detection of the expansion of space by any local measurement is not possible. And if the æther is the substance of the universe that has supposedly expanded, with the galaxies embedded therein, then it is fundamentally undetectable. This assigns cosmology firmly to the realms of philosophy and metaphysics.
