The questions are in order of their appearance in the show. 1 What is the theory about the origin of the universe? 2 Why should the Big Bang not be considered big? Why should it not be called a bang? 3 When did astrologers first divide the sky into the regions that later became known as the zodiac? 4 What group first used mathematics to interpret the heavens? 5 How many planets could they see at that time? 6 Could Ptolemy correctly predict the path of the planets? 7 After the fall of the Roman Empire, much of the knowledge of astronomy was lost. Who was the Polish astronomer who made the next big discovery regarding solar system motion? 8 What was his major discovery? The Universe Astronomy Beyond Header the Big Bang 9 Why did he not publish his works until he was on his death bed in 1543? 10 What the major contribution by Kepler to our understanding of how the universe moves? 11 What technology did Galileo Galilei use to prove Copernicus and Kepler were right? 12 What was the evidence Galileo saw regarding Venus that proved planets orbit the sun? 13 Did Einstein believe in a finite or infinite universe? 14 What was the point that exploded in the Big Bang first called? 15 What is the Steady State Theory? 16 What is the smoking gun that was discovered invalidated one of the 2 major theories of the universe s creation? Specifically, what were they looking for? 17 What was one of the problems scientists discovered with the Big Bang Theory? 18 What was the theory that attempted to resolve this problem? 19 How long after the Big Bang do scientist think it takes before the first star is born? 20 What forms from the left over materials from the formation of a star?

2 21 What happens to Earth as the Sun expands? 22 What happens to the outer planets as the planetary nebula passes them? 23 What is the Big Rip? 24 What causes the Big Rip? 25 From where did the elements come that make up mankind? Neil DeGrasse Tyson (NDT) Clip (31 minutes) 1 List one of the typical questions NDT is routinely asked. Have you ever thought about asking one of these questions? 2 What is the term (misspelling okay and it s not cosmic yoga) that NDT coined to describe what happens as you die in a black hole? What does it mean? 3 What was the asteroid Apophis named for? 4 Exactly, when will Apophis make its first pass at the Earth? 5 What is the term NDT uses to describe the range of locations where Apophis may pass Earth? 6 Exactly, when is Apophis expected to hit Earth and approximately where? 7 Why does NDT say that Earth is not good for life? Give specific facts. 8 Does NDT think that stopping an asteroid is realistic? If so, how?...if not, why? 9 What s the difference between 19 th century astronomy and 21 st century astronomy?...according to NDT? 10 What percentage of species went extinct when the asteroid that took out the dinosaurs hit the Earth? 11 What life forms will survive an asteroid hit and why?
