List of known problems for Big Bang, Black Holes No Math (Version 1, Fall 2013) - This version has the colored plots at the end

(All page numbers refer to the page within the text)

- Forward, Page V: ", and cosmology is what I do for living."  Needs an "a" before "living" 

- Forward, Page VI: "scientists who study it for living" Needs an "a" before "living" 

- Chapter 2, Page 11: "(a billion meters or about a million miles)" would be better said as "(a billion meters or just over a half million miles)"

- Chapter 3, Page 20: The first word on the page appears to be "damental". Of course it is the continuation from the word fundamental from the previous page, but it does look weird. 

- Chapter 3, Page 22: "(Don’t worry—wse still think these things are true!)"  the "wse" should be we. 

- Chapter 3, Page 22 (footnote): "as they way an old piece of fruit decays." should be "the way"

- Chapter 6, page 59: "decade" should be "decades"

- Chapter 6, Page 63, Figure 6.7: "Mater" --> "Matter"

- Chapter 7, Page 71: "they keep orbiting forever." --> "the electrons keep orbiting forever."

- Chapter 7, Page 75 (Figure 7.5): "blue squiggly line" --> "squiggly line". Also, "red line" --> "arrow"

- Chapter 9, Page 103 (Figure 9.6): "... or today’s particle accelerators." --> "or in today’s particle accelerators."

- Chapter 10, Page 117 (Figure 10.3): "... moving to the right." --> "... moving to the left."

- Chapter 13, Page 143 (Figure 13.1): "red line" --> "line inside the graph"  also "red lines" --> "lines in the graph"

- Chapter 13, Figure 13.1, Page 143: On page 143 figure 13.1 the bottom graph is labeled incorrectly. It shows that after the bang ~10^-5 but points to 10^5. This is also used for ~10^-8, -9, -10 values on the line. The axis titles for the x axis are correct.

- Chapter 15, Pages 164-165: "The stars in the disk far outside the center of the bulge orbit in an organized manner, in some ways orbiting our Sun like planets." --> "The stars in the disk, far outside the center of the bulge, orbit in an organized manner which is in some ways similar to how the planets orbit our Sun." 

- Chapter 15, Figure 15.2, Page 166: There should not be an "h)" in the bottom right since there is no figure there. 

- Chapter 16, Page 182: "We note quickly that fusion in the core only happens regularly for stars with a mass of more than roughly 8 percent or more of the Sun's mass" --> " We note quickly that for fusion to regularly occur in in the core of a star, the star must have more than roughly 8 percent of the Sun's mass."

- Chapter 16, Page 187: "...as well as what happens at the end of their life." --> "... as well as what happens at the end of their lives."

- Chapter 16, Page 188, last sentence: "The speeds and violence of this explosion are enormous;" --> "The violence of this explosion is enormous;"

Chapter 18, Page 209: " ...cosmic background radiation look like on the full sky" should read "...cosmic background radiation looks like on the full sky" (i.e., look --> looks. or "look" --> "would look"

Chapter 18, Page 209 (Paragraph 6, last sentence): "Perhaps this method can tell us which of these two hypothesis, if either, best describe the data." Should be "describes". Is that correct? Check with an expert? 

- Chapter 18, Page 210, paragraph 1,sentence 3: "...one special kind of supernova known as Type Ia when it is at its brightest" I believe for clarity this should be "...one special kind of supernova, known as Type Ia, when it is at its brightest"

- Chapter 18, Page 211 (the bottom of the third paragraph in section 18.4 reads) "... and that we have an preliminary accounting..." The "an" should be an "a".

- Chapter 20, Page 232: "at any giving point" --> "at any given point"
