Here's another example of the writers of Scripture having knowledge of things they had know way of knowing. How would they know that things needed to be or were being held together?
These forces (strong and weak molecular forces) scientists have been *discovering* to explain why an atom doesn't fly apart could simply be an outworking of the power of God. But there's no way for scientists to determine the source of the force, only to either detect it or conclude that it's there. So they could be actually measuring the power of God actively at work and not even recognise it. They keep asking for physical evidence for Him and it just might be staring them in the face, but they don't know it. It's just one of the limitations of science. That's where Scripture can fill in knowledge where science is lacking.
