  1. 2. His research into the synthesis of elements in stars, indirectly contributed to big bang modeling by helping to explain the manner in which the first elements of the universe were formed.
  2. 9. The range of wavelengths that trigger brightness and color perception in humans. It lies between UV and infrared radiation.
  3. 12. His equations, which describe the structure of space and time, suggested that the universe should not be static, but that it ought to be expanding.
  4. 13. An instrument that breaks up a wave into a frequency spectrum; for photographing or otherwise recording spectra.
  5. 16. His accidental discovery of a form of radio noise that bathes the cosmos provided a crucial piece of evidence for how the universe was created.
  6. 17. An ensemble of stars, dust, gas and dark matter that are bound together by gravity; contain anywhere between a few hundred million to a hundred trillion stars.
  7. 18. The cooled remnant of the first light that could ever travel freely throughout the Universe

  1. 1. The entire distribution of electromagnetic radiation according to frequency or wavelength
  2. 3. His observation implied that distant galaxies were moving away from us, as the furthest galaxies had the fastest apparent velocities; Stated that if galaxies are moving away from us then at some time in the past, they must have been clustered close together.
  3. 4. Everything we can touch, feel, sense, measure or detect; includes living things, planets, stars, galaxies, dust clouds, light, and even time.
  4. 5. A colorless, odorless, highly flammable gas; by about 75% by mass, the universe created in the big bang was predominantly made of it
  5. 6. An inert gas which is the lightest member of the noble gas series. created the universe's first massive stars
  6. 7. The shift in wavelengths of light toward the blue end of the spectrum as an object moves toward us in space
  7. 8. The study of everything in the universe beyond Earth's atmosphere like the Sun , the Moon , the planets, and the stars .
  8. 10. The ability to do work; the mass–energy density controls the shape and evolution of the universe.
  9. 11. He discovered that the universe is filled with a uniform background radiation, consistent with the view that the universe began with a so-called big bang.
  10. 14. The wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum
  11. 15. The idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now
