Theories of Universe Formation and Change

Match the following vocabulary terms with their corresponding descriptions:

• Big Bang Theory

• A theory that suggests the universe began as a singularity and has been expanding ever since.

• Steady State Theory

• 1. An observation that states galaxies are moving away from us at a speed directly proportional to their distance from us.

• 1. Hubble's law

• 1. A theory that suggests the universe has always existed in a steady state with no beginning or end.

Match the following vocabulary terms with their corresponding evidence or observations:

• Light spectra

• 1. The study of the different frequencies of light emitted or absorbed by celestial objects, providing information about their chemical composition.

• Motion of distant galaxies

• 1. The observed redshift in the light emitted by galaxies, indicating their motion away from us.

• Composition of matter in the universe

• 1. The analysis of the elements found in the universe, such as hydrogen and helium, supporting theories about its formation.

Match the following vocabulary terms with their implications for the formation and changing nature of the universe and our solar system:

• Big Bang Theory

• 1. The idea that the universe is expanding and has been doing so for billions of years.

• Steady state theory

• 1. The concept that the universe is in a constant state with no significant changes over time.

• Hubble's law

• 1. The theory that explains the origin of the universe as a rapid expansion from a singularity, leading to the formation of galaxies and other celestial bodies.
