2. When scientific disputes arise, the ultimate arbiter is not expert authority or common sense but experimental evidence, guided by theory.
3. Theories aren't guesses; they are logically rigorous explanations of observed phenomena that predict new results.
4. Good theories may be superseded by better theories.
5. There are billions and billions of stars.
6. All life is related.
7. As Einstein demonstrated, conceptions of time and space based on everyday life don't apply accurately to all speeds and all realms of space.
