What was the unexpected result that the data showed? (p 137)

How fast is the motion of the Earth orbiting the Sun? (p 137)     What did the large galactic velocity imply? (p 138)

How did this challenge the theory of the universe at the time? (p 138)

How did they make sure that the data wasn't just showing a seasonal effect of the Earth going around the Sun? (p 138)

DYKT the large structures implied by the galactic motion, imply that the cosmic seed must have been present in the early universe. Otherwise they could not have grown so large by now. This focused attention on finding those seeds (p 140, 141)

Robert Roeder thought the data could be explained as zodiacal light. What is zodiacal light? (p 141)

Was he right? (p 141)

Did scientists automatically accept his data? (p 141) 

What was a theoretical objection that was raised? (p 142)

What was another? (p 142)

What is the Hubble flow? (p 143)

How did Vera Rubin (shown) measure galactic velocities? (p 145)

How did Rubin measure their distance? (p 145)

What was the answer to the question that Rubin posed at the American Astronomical Society meeting in 1950, " Does the Hubble flow adequately explain how the cosmic density of galaxies changes over time? (p 143, 145)

How large is the largest supercluster known today? (p 147) *

In the 1950's did most astronomers think that superclusters existed? (p 147)         What are superclusters? (p 147)

Where did The team have to go to prove that their data was not a local effect? (p 148)

What new view of the cosmos had the author help support? (p 152,3)

Did the data show the seeds of superclusters? (p 153) What were the four observational pillars of modern cosmology? (p 153)
