Go to:  HYPERLINK "http://map.gsfc.nasa.gov/m_uni/uni_101bbtest.html" http://map.gsfc.nasa.gov/m_uni/uni_101bbtest.html Big Bang Theory Part 1: Expansion of the Universe How did scientists originally view the idea of an expanding universe? Why did Einstein develop the cosmological constant? Which theory was the natural beginning of a Big Bang theory? Who showed that the universe was indeed expanding? How does our distance from galaxies relate to their speed at which they are moving away from us? What kind of Doppler Shift did Hubble observe in these distant galaxies? According to the expansion law do the galaxies expand away from each other equally? Explain. Part 2: The Abundance of Light Elements What is nucleosynthesis? Describe 2 characteristics of the early universe. What is Big Bang nucleosynthesis? How much of the universes ordinary matter is thought to be helium? Does Big Bang theory support this number? What is WMAP? Where do elements heavier than lithium come from? What are some of these elements? (from #13) Where do elements heavier than iron come from? Ultimately, from where does all carbon-based life come from? Part 3: Cosmic Microwaves What is CMB? Where did it come from? Who predicted the existence of CMB? Who discovered CMB? Describe the CMB as it exists today. What type of light does it look like now? Where can we detect CMB? Explain why looking at distant objects is like looking in the past. How old is the universe thought to be? What did the FIRAS experiment show? What event was thought to occur about 400,000 years after the Big Bang? About how big was the universe at this time? What is the most striking characteristic of the CMB? The article mentions cosmology and cosmologists over and over again. What is cosmology? (You can look this up if you need to) Beyond Big Bang Part 1: Structure What does the WMAP satellite measure? How do most cosmologists believe galaxies today grew? When was the universe one thousandth its present size? What does the COBE satellite detect? What are 2 popular ideas of what cause fluctuations? Part 2: Fluctuations What can offer great insight into the origin and evolution of the universe? What is dipole anisotrophy? What allows scientist to infer a great deal of additional information about the early universe? On the fluctuation maps what do blue and red colors mean? Part 3: Inflation What is the inflation theory? What are the three problems with the Big Bang Theory? How much did the universe increase in linear size in only a fraction of a second? How does inflation solve the three problems with the Big Bang Theory?
