Across
  1. 4. point in which matter is infinitely dense, as in the center of a black hole or the universe at the very beginning.
  2. 6. by equal but opposite charges that are separated by a short distance
  3. 7. Space Telescope/a space telescope and camera named for a famous astronaut (Edward Hubble) used to study space elements
  4. 8. huge group of single stars, star systems, star clusters, dust, and gas bound together by gravity
  5. 9. of the universe
  6. 11. Fireball/Extremely high frequency radiation that filled space immediately following the Big Bang
  7. 12. Forces/4 forces that act throughout the universe. They include gravity, electromagnetic force, strong nuclear force and weak nuclear force
  8. 14. Era/time period greater than 500,000 years since the Big Bang where larger masses, such as stars, formed
  9. 15. slightly unstable star that has a regular variation in brightness and luminosity due to a periodic expansion and contraction in its outer layers.
  10. 16. of light to a longer wavelength as it moves away
  11. 17. point in which matter is infinitely dense, as in the center of a black hole or the universe at the very beginning.
  12. 18. (shape)/A position or moment of stillness
  13. 21. measure of how hot or cold something is.
  14. 22. Shift/the shift to a different wavelength
  15. 23. Matter/matter that does not give off electromagnetic radiation but is quite abundant in the universe
  16. 25. unit for temperature
  17. 27. for measuring intensity of light
  18. 28. Lines/The wavelengths where a specific element can absorb or emit light
  19. 29. Fusion/a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
Down
  1. 1. Hole/An object in space whose gravity is so strong not even light can escape.
  2. 2. of exponential expansion of space in the early universe.
  3. 3. interaction between electricity and magnetism
  4. 5. study of energy transformations that occur in a collection of matter.
  5. 10. Doppler shift in which spectral features are shifted to shorter wavelengths, observed when an object is moving toward the observer.
  6. 13. Bang Theory/The theory that the universe originated in a huge explosion that released all matter and energy.
  7. 15. Density/The theoretical density of the universe that would create a flat universe.
  8. 19. consisting of antiparticles of normal substances
  9. 20. apparent shift in the position of an object when viewed from different locations
  10. 24. volumes of space between superclusters that appear to contain very little matter
  11. 26. Background Radiation/The electromagnetic radiation left over from the big bang
  12. 30. distance light travels in one year
