CHAPTER 6

What is cosmic background radiation? (p 114)

How could one determine if the universe is rotating? (p 114, 115)

What is a singularity? (p 115)

What is one way to for the universe to expand and contract that avoids a singularity (p 115)

What did the Michelson Morley experiment in 1887 show? (p116)

What does it mean when the book says that light propagates at 186,000 mile/s regardless of the observers frame of reference? (p 117)

How can we determine the earth’s motion relative to the background radiation? (p 117)

How large was the estimated difference in temperature (p 119)

What is a DMR and why is it sensitive? (p 121)

How high is White Mountain in California? (p 121, 122)

How high could balloons go? (p 122) 

Why was it so important to be high? (p 122)

What were to two problems with the C-141 aircraft? (p 122)

What was eventually used to hold the observation equipment? (p 122)

How high could it go? (p 123)

How many miles is that? (5280ft/mi)

Where did the U2 store its fuel? (p 124)

How many passengers could the U2 hold? (p 125)

What four things might be sources of noise for the DMR? (p 126)

What was the wavelength of the radiation they were looking for? (p 126)

Why was that wavelength chosen? (p 126,7)

What path did the U2 fly and why (p 127)

What was the second 54-Ghz DMR for? (p 127)

Because the team couldn't eliminate heat sources on the "horns" that shield the antennas, what did they try to do? (p 127,8)

If you had had a very frustrating day and left work to find people relaxing on the grass, what would you think? (p 128)

What did Marc Gorenstein think? (p 129)

How did they make sure that both antennas would read the same temperature if the temperature they were reading was the same? Why was this important? (p 132)

When was the first U2 launch? (p 133)

How long had they been working on the project? (p 133)
