.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Relativity predicts that nothing can travel faster than the speed of light in a vacuum - How can it move slower?

Electromagnetic Radiation: Infrared

6. The Big Bang was not an explosion of matter into empty space - like the explosion of a bomb. Instead - it was an emergence of space and time filled with pure energy where before none of this was present. The point from which is emerged is called the

7. Is there water on the moon?
In an expanding universe all galaxies see all other galaxies that are not gravitationally bound to them receding away. This is what we see in the Hubble Law. We infer that the Hubble law also holds true for all other galaxies.

13. Distribution of dust (tells us disk is thin) - find distances to O&B stars and H2 regions (arms are sights of star formation and OB stars live and die at location of birth) -Milky way has four arms. Sun is in spur apart from arms.
Gravity only pulls matter back together. Therefore - if gravity is the only force that operates on cosmic scales then the expansion of the universe should decrease with time. The critical density is the value of matter density sufficient to halt the
Electron
Dark matter is located at center of clusters - pulling the cluster members into faster orbits--dark matter gravity keeps objects in galxies bound.

14. A very low mass particle formed in solar fusion reactions that reacts only weakly with matter

15. Star speed at outer edge of galaxy should begin to diminish - but they dont so we guess that this means there is increasing force (aka dark matter)

16. Why does the earth have few craters while the moon has many?
We don't know. It might be but does not have to be.

In an expanding universe all galaxies see all other galaxies that are not gravitationally bound to them receding away. This is what we see in the Hubble Law. We infer that the Hubble law also holds true for all other galaxies.
