  2. A universe that stops expanding only after an infinite Amount of time

  3. Flat Universe

  4. A universe with enough matter to eventually stop The expansion and recollapse

  5. Closed Universe

  6. . A universe with too little matter to stop the expansion

  7. Open Universe

  8. An assumption that the universe is everywhere Uniform and looks the same in any direction in all space and Time.

  9. Perfect Cosmological Principle

  10. An estimate of the age of the universe obtained by Taking the inverse of a specific constant, only valid If the expansion rate of the universe is constant at all Times in its history.

  11. Hubble Time

  12. Period of time before 1 million years after the start of the Expansion of the universe, when energy was more Dominant than matter.

  13. Radiation Era

  14. Radio energy that is nearly uniform in all directions and has a nearly perfect thermal spectrum.

  15. Cosmic Microwave Background Radiation

  16. The problem that if the universe is infinite in size and age, then the night sky should everywhere be as bright as the sun no matter the direction being looked at

  17. Olbers’ Paradox

  18. The time about a million years after expansion of the universe began when it became transparent

  19. Decoupling Epoch

  20. The time about 1 million years after the big bang’s beginning, when most of the ions and electrons In the universe combined to form atoms

  21. Recombination Epoch

  22. A type of matter that destroys ordinary matter when they come into contact with one another

  23. Antimatter

  24. The force that caused the expansion of the universe to expand and accelerate

  25. Dark Energy

  26. The undetectable quantity that helps hold galaxies together. It can be deduced due to gravity.

  27. Dark Matter

  28. The value of the average density of the universe must equal or exceed if the universe is closed.

  29. Critical Density

  30. When the charges on the two particles cancel and the Mass of the particles is entirely converted to energy

  31. Annihilation

  32. The explosive event at the beginning of the universe

  33. Big Bang

  34. The self-repelling property of space first proposed by Einstein

  35. Cosmological Constant

  36. Everywhere uniform in appearance so that there is no preferred observing position

  37. Homogeneous

  38. A brief period of extremely rapid and enormous expansion that may have occurred very early in the history of the universe.

  39. Inflation

  40. Looking the same in all directions

  41. Isotropic

  43. 49ers

  44. Coach Villegas’s age

  45. 30

  46. Coach Villegas’s favorite NBA team

  47. Mavericks
