What do we call a force that opposes gravity and is said to be why the universe is expanding?

• Dark Matter

• Dark Energy

• The Big Bang Theory

• Cosmic Background Radiation

The big bang theory states that all matter and energy was...

• compressed into a small volume and then expanded in all directions.

• formed from the spectra of nebula in space.

• absorbed by giant black holes and then expelled into space.

• in a large volume at first and started to contract inward.

The temperature of cosmic background radiation is...

• almost absolute zero.

• about 270 degrees C.

• above 3,000 degrees C.

• about 0 degrees C

Red shift in the light of galaxies told Hubble that...

• the universe is expanding.

• the universe is composed primarily of red light.
