Explain the Big Bang
What is the start of the universe where all matter was concentrated in a place smaller than a pin and then rapidly expanded.
100
Stars of this color are the biggest ones.
What are blue stars.
100
A star is made up of these two elements.
What are Hydrogen and Helium
100
What is brighter: a red star or a blue star?
What is a Blue star.
200
Microwaves left over from the Big Bang.
What is Cosmic Microwave Background Radiation
200
What is a nebula.
What is a cloud of gas and dust that stars are born from.
200
Yellow stars are this size (small, medium, large).
What is medium.
200
Which is hotter: the hottest star in the main sequence or the hottest Red Giant?
What is a star in the Main Sequence.
300
Explain Hubble's Law (dealing with raising bread)
What is the theory that the universe is expanding faster on the outside of the universe than the inside.
300
This is a cloud of gas and dust that stars are born from.
What is a nebula.
300
This is what a supernova contributes to the universe.
What are all the elements heavier than Fe (Iron).
300
What is the luminosity of the sun?
What is 1.
400
Name two evidences for the big bang.
What are red shift and CMBR.
400
This is the next stage of a Red Supergiant.
What is a Supernova.
400
True or False: The final stages of a star's life depend on its mass.
True
400
This is the stage called immediately after the big bang when the universe expands extremely fast.
What is inflation.
500
The reason 1. red shift and CMBR are evidence for the big bang.
Red shift shows that galaxies are moving away from each other at a constant rate showing that they were once very close together. CMBR is energy that could only have been produced by an event as large as the big bang and it is also present everywhere in the universe showing that it came from the whole universe.
500
These are the two forces that keep a star from collapsing or floating off into space.
What are gravity and nuclear fusion.
500
Name 2 possible end stages of a star
What are a black hole or a white dwarf.
500
Which of the following characteristics of a star determines how long it lives? (Color, Size, Stage of life, distance from the center of the universe)
What is its Size.
