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.

According to the Big Bang Theory, what is happening to the size of the universe?

• The universe is growing

• The universe is shrinking

• The universe is staying the same size

• The universe rides on the back of four elephants, supported by a turtle.

What does the BBT hypothesize about the size of the early universe?

• The universe used to be much much larger than it is today.

• The universe used to be a tiny speck of super-dense matter.

• The universe has always been the same size

Which of the following objects is the biggest?

• Solar system

• Universe

• Galaxy

• Star

What is Hubble's Law?

• The farther away a galaxy is from us, the faster it moves away from us.

• The farther away a galaxy is from us, the slower it moves away from us.

• The closer a galaxy is to us, the faster it moves away from us.

• The more red light we observe from another galaxy, the closer we are to that galaxy

If a galaxy is moving very quickly away from us, the light we receive from that galaxy will be:

• more red

• more blue

• more green

• more yellow

If an object is making noise and moving quickly towards us, we will observe:

• the pitch of the noise will be higher than if the object wasn't moving

• the pitch of the noise will be lower than if the object wasn't moving

• the volume of the noise will be louder than if the object wasn't moving

• the volume of the noise will be softer than if the object wasn't moving
