Across
- 4. any substance that has mass and occupies space
- 6. a theory that the universe started from an explosion that slowly expanded
- 7. the study of the universe
- 10. when light waves are "stretched out," in other words this means what our eyes can see is the light that moves toward the red side of the spectrum and it gives scientists the idea that the universe is expanding
- 12. concrete, verifiable information that either supports or disproves a claim
- 17. the quality that defines how much energy a star is actually giving off
- 19. a unified account of the entire history of the Universe that uses evidence and ideas from multiple disciplines to create a broad context for understanding humanity
- 20. using your reasoning to come to a conclusion
- 23. a "gut feeling" that is not necessarily based on logic or evidence
- 24. center of the earth
- 26. the study of the Earth, including its composition and history
