Big Bang Theory
The explosion that lead to the universe.
What is the Big Bang?
This shows where radiation falls in relation to eachother.
What is the Electromagnetic Spectrum?
What is luminosity?
Change in wave frequency as wave producing object moves further or closer.
What is the doppler effect?
The beginning of star formation starts with this.
What is an interstellar cloud of dust?
Radiation we use as evidence of the Big Bang.
What are Microwaves?
Patterns of distance between waves from electromagnetic radiation.
What are wavelengths?
What you observe when looking at a star.
What is apparent brightness?
When visible light wavelength is stretched out as light producing object moves further away.
What is red shifting?
The shape that forms from all the particles/dust as stars are forming.
What is a disc?
This is found before the big bang.
What is nothing?
How many sections the EM spectrum is divided into.
What is 7 sections?
Does not change if a star moves closer or further away.
What is Luminosity?
Causes shorter wavelengths.
What is moving towards you.
This left over interstellar dust and particles form these after stars are formed.
What are planets?
Decrease in wavelength lead to this.
What is an increase in energy?
Is affected by how close the star is.
What is apparent brightness?
Causes longer wavelengths.
What is moving away from you?
The element that fuses together in stars to form helium.
What is hydrogen?
Theory that all gravity and matter will collapse on itself, and form another Big Bang.
What is the closed universe?
Increase is wavelength lead to this.
What is a decrease in energy?
This is how you would define apparent brightness.
States that objects further away move away faster, and objects closer move away slower.
What is Hubble's Law?
This causes the cloud of dust and particles to begin forming clumps.
