What are some of the scientific ideas contained in the Bible that were not known to science until much later?

It’s interesting to me that the Bible contains much scientific knowledge and facts that were not known or understood until recent times, yet how did the people that wrote the Bible know of them unless it was inspired by God. The universe is expanding, the fountains of the deep, the hydrological system of evaporation and rain, that air has weight, the atomic makeup of the universe (Hebrews 11:3), the earth is round and hangs on nothing in space, that light travels in waves and much more. Seems that someone very intelligent wrote the Bible but the authors were not science leaders of their day…any explanations? Does anyone have more science related facts in the Bible to add.

The wrong value for “pi”? This argument has been laid to rest many times–see link for explanation—god’s Word is true.

Hebrews 11:3
By faith we understand that the universe was formed at God’s command, so that what is seen was not made out of what was visible.
Is that a pretty fair description of atomic level of the makeup of the universe? You can’t see atoms yet they are the fundamental building blocks of everything. How would a person in biblical times know to write that?
