Summary of Previous Day Science is limited to

Summary of Previous Day Science is limited to observing nature and explaining how the natural world works—religion answers questions about the purpose of everything and a supernatural being. All we can know about space depends on our understanding of light. Knowing about the spectrum produced by the different elements helps us determine the composition of matter based on the light received from an object.

“ I can construct an explanation of the Big Bang theory based on astronomical evidence of light spectra, motion of distant galaxies, and composition of matter in the universe. Next Generation Science Standard ESS 1 -1 Learning Target 10. 1 ”
