| Question | Answer |
|---|---|
| How old is the universe? | The Universe is 14 billion years old. |
| What event began the universe? | The event that started the universe is the Big Bang |
| What are the visible forms of light? | Visible forms of light are infrared and UV light |
| What is a light year? | Distance light travels in one year. |
| Explain Red Shift. How is blue shift different? | Red shift is objects or planets moving farther away from us. Blue shift is the opposite, objects/planets move towards us |
| How is the universe moving and what shift of light do you see? | The universe is expanding and we see red shift in that movement. |
| On the EM Spectrum different colors happen because of what? | Different colors happen because of the wavelength |
| How does temperature relate to density? | It is a indirect relation. Higher temperature means lower mass. |
| What are two ways you can increase gravity? | Increase the mass or shorten the distance |
| What are CMB's and why are they important? | CMB shows the amount of temperature and density areas had to form solar systems. It is important because it is a big piece of evidence for the Big Bang Theory |
| Stars and galaxies in the inverse start in what type of temperature, density and gravity regions? | They start in low temperature with high density and high gravity regions. |
| Describe what the different colors in the CMB represent and how they are related to temperature and density. | The different colors represent different areas of density. The temperature and density have an indirect relation. |
| Describe the relationship between wavelength, frequency and energy. | Longer wavelength is lower frequency and lower energy. |
| Describe and Explain how the Universe got from the Big Bang to how it looks today (make sure to include density, temperature and star and galaxy formation). | The temperature started to cool down and which caused more density, this is how our solar system was formed and how it is now. |
| Formula for Eccentricity | E=d/L |
| What is the minimum eccentricity an ellipse can have? | The minimum eccentricity an ellipse can have is 0. |
| What is the name of the geometric figure with 0 eccentricity? | The figure is called a circle. |
| What does the process of nuclear fusion produce? | The process of nuclear fusion creates energy and it is released. |
| What is the ratio of hydrogen to helium in the early universe? | The ratio of hydrogen to helium is 3H:1He |
| The universe was primarily made up of what elements? | Hydrogen Helium and oxygen |
| What is the temperature of the CMB right now? | The temperature of the CMB right now is 27K |
| What causes different colors in visible light? | The wavelength and frequency cause different colors. |
