Question | Answer |
How old is the universe? | 14 billion years old |
what event began the universe | the big bang |
what are the forms of visible light | indigo,blue,yellow,red,orange |
what is a light year | how far light travels in a year |
red shift | the light coming at us when a object is moving away |
blue shift | the light coming at us when a object is moving closer |
what way is the universe moving | every direction and is expanding |
on the em spectrum different light show because | different frequency makes different light |
how does temputure relate to density | the colder the object the closer the molecules and the denser it becomes |
what are two ways you can increase gravity | enlarge a object or get closer to the object |
what are CMB's and why are they important | it is the radiation from the big bang and it it the reason why the universe is still growing in every direction |
how does densty relate to gravity | directly the more density an object has the more gravity it has |
what happens in the colder areas of CMB | the colder areas have more gravity and often have more density |
Stars and galaxies in the universe start in what type of temperature, density and gravity regions? | |
Describe what the different colors in the CMB represent and how they are related to temperature and density. | the red are the hot temperatures and are not very dense of have much gravity, the blue has more gravity and often has more density. |
Describe the relationship between, wavelength, frequency and energy? | they are all directly connected because the more energy they wave the higher the frequency and the higher frequency the shorter the wave length |
Describe and Explain how the Universe got from the big bang to how it looks today | the universe kept expanding from CMB and moving everything and spreading everything apart to what it looks like now |
