Chapter 14

What is the "conundrum" for cosmology that is mentioned on p 273?

Why are they trying so hard to find systematic errors? (p 274) *

What systematic error in the data was Al Kogut able to find in 1992? (p 274)

One they convinced themselves that the signals were real, what did they do next? (p 275)

What caused the only day to day change in the dipole data? (p 276)

When was the CBR formed? (p 276) 

Smoot predicted the wrinkles would be scale invariant. What does that mean? (p 278)

DYKT one common example of size invariance is a fractal. The Fractal Microscope web site lets you play around. Zoom in on fractals and you can see they that they look about the same on all length scales!! A very cool site. http://www.shodor.org/master/fractal/software/

What does Smoot think might have caused these fluctuations? (p 278)*

Why was the quadripole signal so faint? (p 280)

In what way do each of the five observations listed on pg 283 support the BB theory?

Pages 284,5 have a great summary of the early universe.

DYKT when the temperature of the universe fell to about 3,000 degrees the energy of the photons (light) could no longer break up atoms. This has two results 1) atoms can now be stable. 2) CBR photons are free to move through the universe (it becomes transparent). (p 285)

Is CBR from denser regions warmer or cooler than average? (p 285)

Why would dark matter have formed structure much earlier than visible matter? (p 286)

What is Smoot’s analogy for the way that dark matter acted as a foundation for the large scale structure of the visible matter? (p 286)

What is the Great Wall of cosmology? (p 286)

A theory that was competing with inflation in 1992 also made predictions about wrinkle in CBR. How were they different then the prediction made by the inflation theory? (p 287)

Does Smoot think that the early universe was more simple or more complex than the modern one? (p 291)

What is the anthropic principle and what does Smoot think of it? (p 293)

DYKT the Texas superconducting supercollider (SSC) was never built?*

What did you think of the book? (p 1 – 297)
