  1. 6. Light from an object moving towards an observer shifts to shorter, higher-frequency wavelengths, making it appear bluer
  2. 7. Nstruments that split electromagnetic radiation (light) into its component wavelengths
  3. 11. German-born physicist and activist who revolutionized physics with his theory of relativity and made significant contributions to quantum theory.
  4. 12. Renowned American avant-garde playwright, director, and visual artist known for his revolutionary, slow-paced experimental theater that merged architecture, lighting, and movement.
  5. 14. The lightest, simplest, and most abundant chemical element, atomic number 1
  6. 16. A colorless, odorless, tasteless, nonflammable noble gas
  7. 17. The capacity to do work, cause change, or move matter, measured in joules

  1. 1. The narrow band of electromagnetic radiation that the human eye can detect
  2. 2. German-American astrophysicist who co-discovered the cosmic microwave background (CMB) radiation, providing crucial evidence for the Big Bang theory
  3. 3. A distinguished British astronomer and mathematician famous for co-developing the stellar nucleosynthesis theory—explaining how elements are created inside stars—and for coining the term "Big Bang".
  4. 4. The faint, nearly uniform, remnant heat left over from the Big Bang, filling all space in the observable universe
  5. 5. The prevailing scientific model explaining that the universe expanded from an extremely hot, dense
  6. 8. The totality of all space, time, matter, and energy
  7. 9. The stretching of light toward longer, redder wavelengths as an object moves away from the observer or as space expands
  8. 10. Study of everything beyond Earth’s atmosphere, including planets, stars, galaxies, and the universe's large-scale structure
  9. 13. A pioneering American astronomer who revolutionized cosmology by proving that galaxies exist outside our own and that the universe is expanding
  10. 15. A massive, gravitational bound system consisting of stars, stellar remnants, interstellar gas, dust, and dark matter
