1 Formation of the Universe Review

2 observed change in the frequency of a wave when the source or observer is moving

3 Doppler Effect

4 theory that all matter and energy in the universe exploded 10 to 15 billion years ago and began expanding in all directions.

5 Big Bang Theory

6 apparent shift toward shorter wavelengths of light when a luminous object moves toward the viewer

7 Blue Shift

8 theory that matter distorts space

9 General Theory of Relativity

10 sum of all space, matter and energy

11 Universe

12 matter not visible through current methods, but observable through gravitational interactions between galaxies

13 Dark Matter

14 apparent shift toward longer wavelengths of light when a luminous object moves away from the viewer

15 Red Shift

16 steady but faint microwaves from all over the sky

17 Cosmic Microwave Background Radiation

18 unexplained high speed of galaxies going into outer space
