What would we expect to happen to the orbital speed of stars at the edges of a galaxy?
Orbital speed should decrease as distance from the center of the galaxy increase
Orbital speed should increase as distance from the center of the galaxy increases
Trick question! Stars do not orbit, only planets do
Orbital speed varies according to the age of the star, so it’s hard to say

True
False
When a star moves away from us, the light it emits in our direction is stretched causing the wavelengths to get longer. This is called
Blue Shift
Red Shift
The Doppler Effect
Cosmic Background Radiation
Red Shift is one of the key pieces of evidence used to support the universe is
expanding
contracting
exploding
freezing
Red Shift supports the big bang theory because...
the stretching of wavelengths toward the red end of the visible spectra suggests that as light moves across the universe it is experiencing expansion.
the contracting of wavelengths toward the red end of the visible spectra suggests that as light moves across the universe it is experiencing contraction.

True
False
The shadows in the Cosmic Background Radiation can give scientists an idea where there are...
giant clumps of matter in the universe (galaxies)
black holes
energy rich spaces
potential other singularities
Cosmic background radiation is a key piece of evidence supporting the big bang because...
scientists were able to use what they understood about red shift to make predictions with the model
scientists found what they predicted would happen
Scientists are infatuated with it because it makes a really cool map
scientists are able to use it now to further inform that the universe may have looked like in the past
