How was Hubble able to calculate a rough estimate for the formation of the Universe?

• By calculating when hydrogen was first formed

• By calculating the age of the oldest atoms

• By calculating the rate at which the Universe is expanding

• By calculating the rate at which the Universe is shrinking

According to the standard model of Big Bang cosmology, approximately how old is the Universe?

• 65 million years old

• 3.8 billion years old

• 13.7 billion years old

• 4.5 billion years old

What is cosmic microwave background radiation (cosmic background radiation)?

• Energy released during the fusion of hydrogen nuclei in the center of stars

• Energy used in the laboratory to sterilize equipment

• Energy released 380,000 years after the Big Bang

• Energy emitted by the Sun

What are two important pieces of evidence we have for the Big Bang?

• Ptolemy’s work on epicycles and Hubble’s law (the expansion of the Universe)

• Hubble’s law (the expansion of the Universe) and cosmic background radiation

• The fact that we have multiple Universes to compare and study and cosmic background radiation (CBR)

• The abundance of hydrogen, helium, and lithium found in the Universe and Ptolemy’s work on epicycles

The Big Bang Theory states that all matter started as a small volume and then...

• expanded in all directions

• contracted even smaller

• caused an atomic explosion

• burned up and exploded

• Nothing

• Redshift

Why does redshift occur in stars/galaxies?

• Light waves stretch as a star moves away

• Light waves squish as a star moves away

• Redshift does not occur in stars

• Light waves change shape as stars move
