Origins of the Universe
This happened 14 billion years ago, and is considered the birth of space and time. Gravity pulled matter into clumps, creating galaxies and stars, and those galaxies and stars moved further away, signifying an expanding universe.
What is the Big Bang
A system of billions of stars, together by gas, dust, and black holes held by gravity.
What is a Galaxy
These things start as Stellar Nebula, and follow the path of Main Sequence, Red Giant, Planetary Nebula, and eventually, White Dwarf
What is a Star
This is extremely dense and exotic matter
What is a Black Hole
This is essentially the explosion of a star
What is a Supernova
This is a remnant from the Big Bang.
What is Cosmic Microwave Background Radiation
These four things compose the anatomy of a Galaxy
What are Disc, Bulge, Halo, and Globular Clusters
This is a diagram Graph used to determine: Luminosity, Temperature, Spectral class, Star Phase
What is an HR Diagram
These are the four types of Black Holes
What are Stellar, Intermediate, Supermassive, and Miniature
This is caused by binary stars, specifically a red giant and a white dwarf
What is a Type 1 Supernova
These elements were created soon after the Big Bang
What are Hydrogen and Helium
These are the five types of galaxies
What are Spiral, Elliptical, Lenticular, Irregular, and Barred Spiral
If the luminosity of a star is 1, that means it's just as bright as this other star
What is the Sun
This causes Black Hole evaporation
What is Hawking Radiation
This is caused by massive stars with a collapsed core
What is a Type 2 Supernova
The light we observe from galaxies has been stretched by the time it reaches us. This is the result of galaxies moving away from us.
What is Redshift
This is the Classification Scheme of Galaxies
What is the Hubble Classification Scheme
The surface temperature corelates to this attribute of a star
What is the color
This is not proven to exist, but is assumed to be the antigravity of a Black Hole
What is a White Hole
This is how close a Supernova would have to be to us to be dangerous
What is 30 light years
These are the three theories of the universe.
What are the Open Universe, Closed Universe, and Flat Universe theories
Contains 50 or few galaxy members held by gravitational force
What is the Local Group
The temperature of a star is classified in this unit
What is Kelvin
This is essentially the center of a Black Hole
What is a singularity
These are the other two types of stellar explosions
What is a Hypernova and Kilonova
