This describes when light waves are stretched and shifted toward longer wavelengths
What is Redshift
Two galaxies encounter and move through each other
What are Collisions
This term refers to large structures made of many galaxy clusters linked together
What is a supercluster
This model describes protogalaxies collapsing rapidly to form elliptical galaxies
What is the Top-down model
This classic 1999 movie offers its protagonist a choice between a red and blue pill to learn the truth about reality
What is The Matrix
This galaxy shape is active with younger stars
What are spiral shaped
When galaxies collide/merge, this type of event often occurs, creating a sudden surge of new star formation
What is a starburst
These small collections of galaxies are held together by gravity
What are groups
This model describes protogalaxies merging over time to create elliptical and spiral galaxies
What is the Bottom-up model
This desert planet is the home of Luke Skywalker
What is Tattooine
This property of a galaxy determines age and activity level
What is color
This term means the universe appears the same in every direction you observe

What is a void
This sphere of matter formed first after the Big Bang, pulling in gas
What are Dark Matter Halos
This is the name of the black hole in the movie Interstellar
What is Gargantua
This phenomenon is observed through spectral shifting to determine motion and direction
What is the Doppler Effect
This supports the Big Bang theory by suggesting the universe expanded evenly in all directions
What is the cosmological principle
What is the Local Group
This is the name of "before" galaxies that merge to create larger structures in the Hierarchical Galaxy Formation stage
What are protogalaxies
This character carries the One Ring to Mount Doom
Who is Frodo Baggins
This is the measurement of the speed of an object moving towards/away from an observer
What is Radial Velocity
The type of galaxy likely to form from the merger of two spirals?
What is an Elliptical Galaxy
This substance causes light to bend more than it should and galaxies to spin too fast
What is Dark Matter
This percentage of dark energy makes up the composition of the universe
What is 68%
