The theory stating the universe originated from a hot, dense singularity 13.8 billion years ago is the:

• Big Crunch Theory

• Big Bang Theory

• Oscillating Universe Theory

• Steady State Theory

Which theory, proposed by Fred Hoyle, suggests the universe is expanding but density remains constant?

• Creationism Theory

• Oscillating Universe Theory

• Steady State Theory

• Big Bang Theory

The Oscillating Universe Theory was proposed by:

• Richard Tolman

• Edwin Hubble

• Fred Hoyle

• Robert Wilson

The belief that the universe was created by a Supreme Being is called:

• Cosmology

• Creationism Theory

• Intelligent Design Theory

• Steady State Theory

The redshift observed by Edwin Hubble indicates that:

• Galaxies are moving toward us

• Light shifts to longer wavelengths

• The universe is shrinking

• Stars are cooling rapidly

The constant proportion of hydrogen (74%) and helium (24%) in the universe supports:

• Cosmic Inflation Theory

• Big Bang Theory

• Steady State Theory

• Stellar Evolution Theory

The remnant heat from the early universe detected by Penzias and Wilson is called:

• Solar Radiation

• Cosmic Microwave Background Radiation

• Infrared Radiation

• Stellar Radiation

The process in the Big Bang that formed hydrogen, helium, and lithium is called:

• Stellar Nucleosynthesis

• Big Bang Nucleosynthesis

• Supernova Nucleosynthesis

• Alpha Process
