High School Astrophysics Student Text
The word “astronomy” comes from two Greek words — one that means “star” and the other that means “to arrange.” Thus, very literally, the word astronomy means “to arrange stars.” This text focuses on what is known as “astrophysics.” This considers what is learned in astronomy, yet goes a little deeper into how the universe began, how it works, and how things like black holes, dark matter, and gravity are used by God to sustain His creation. Genesis 1:1 tells us that God created the heavens, along with the Earth, in the beginning. God made the sun, moon, and stars on the fourth day of creation, and the study of the heavens is the science that the Bible most explicitly mentions. Psalm 19:1 reveals that one purpose for the heavens is that they declare God’s glory.
