Big Bang Practice Games to help you prepare for your test

What is the Big Bang theory?

• The theory that the universe is expanding and that it emerged from a tiny region

• The theory that the universe is contracting and will eventually collapse

• The theory that the universe has always existed in its current form

• The theory that the universe is static and unchanging

What does the hydrogen-helium ratio of stars and interstellar gases indicate?

• The ratio of hydrogen to helium can provide evidence for the early universe

• The ratio of hydrogen to helium determines the age of the star

• The ratio of hydrogen to helium indicates the distance of the star from Earth

• The ratio of hydrogen to helium has no significance

What does the redshift of galaxies indicate?

• The galaxies are moving away from the observer

• The galaxies are moving towards the observer

• The galaxies are stationary

• The redshift of galaxies has no significance

How is evidence collected in support of the Big Bang theory?

• Through a variety of valid and reliable sources

• Through personal opinions and beliefs

• Through random experiments

• Through fictional stories

Why does the observed redshift for most galaxies support the idea of an expanding universe?

• Redshift indicates that an object is moving away from the observer

• Redshift indicates that an object is moving towards the observer

• Redshift has no relation to the motion of objects

• Redshift is a result of atmospheric interference

How does the observed background cosmic radiation support the Big Bang theory?

• It is consistent with a universe that was very dense and hot in the past

• It is consistent with a universe that is currently expanding

• It is consistent with a universe that is contracting

• It has no relation to the Big Bang theory

What does the ratio of hydrogen to helium indicate about the early universe?

• It suggests the formation of nuclei from colliding protons and neutrons

• It suggests the formation of atoms from nuclei plus electrons

• It suggests the formation of galaxies

• It suggests the formation of black holes
