The universe remains static or unchanged in motion.
None of the above
Light emitted from a star or galaxy can be separated into a band of colors, called a ________.
Red Shift
Wave Length
Spectrum
Microwave
Where is the center of the universe located?
There is no center of the universe.
At the center of the Milky Way galaxy.
14.5 billion light years away from Earth.
In a large singularity near the Andromeda Galaxy.
What does the Big Bang Theory tell us
About the popular television show.
the entire universe was once condensed in the form of primeval atom, or a dense mass.
how the universe began.
As galaxies move away from our galaxy
a shift of the absorption lines on the electromagnetic spectrum
is noticed. This phenomena is
called _____________.
redshift
blueshift
unshift
blackshift
the universe must have been smaller.
Astronomer Edwin Hubble discovered (in 1929) that allmsot all galaxies seem to be
rushing toward each other.
getting larger by galactic mergers
rushing away from each other.
spiral in shape
Hubble's Law states that most galaxies are receding away from us at a speed that is directly proportional to their
size.
mass.
type.
distance
A galaxy is at a distance of one billion light years from Earth. Which of the following is true?
We see the galaxy as it was one billion years ago.
We see the galaxy as it was when the universe was one billion years old.
We see the galaxy the way it will be in one billion years.
We see what our galaxy will be like in one billion years.
You observe three distant galaxies and note their apparent velocities:
- BFG-01 40,000 km/s
- BFG-02 80,000 km/s
- BFG-03 20,000 km/s
Which of the following is true?
BFG-01 is farthest away from Earth.
BFG-02 is closest to Earth.
BFG-03 is closest to Earth.
Nothing can be learned from their apparent velocities.
Our universe is
expanding.
shrinking.
staying the same size.
We don't know what it's doing.
Cosmic Microwave Background Radiation is a form of _________.
Matter
Energy
Neither of these
Why is the light from distant galaxies red-shifted?
They produce more red light than nearby galaxies
They are moving away from us
The absorption lines shift to the red side of the spectrum
They are getting bigger
The "afterglow" leftover energy from the origin of the universe that we see today.
Cosmic microwave radiation
sunlight
Doppler effect
Cosmic explosions
What happens to the wavelengths of energy if they are moving AWAY from a source?
The waves stretch out and get longer.
The waves compress and get shorter.
How does Cosmic Microwave Background Radiation support the Big Bang Theory?
Microwaves are found everywhere in the universe.
Microwaves occurred at the time of the Big Bang
Microwaves are useful in our everyday lives
What is true about these stars?
Both of these stars are moving away from us.
Both of these stars are moving towards us.
As time increases, the size of the universe decreases
As time increases, so does the size of the universe
The size is constant over time
Size increases up to a certain point and then decreases over time
Red light is more common coming from these stars and galaxies
Cosmic microwave background radiation supports the fact that...
The universe used to be much hotter but has cooled
The universe used to be much denser but has expanded
The universe used to be much denser but has expanded
All of these are true
