Chapter 13, Problem 21SEQ

Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.

*21. Uniformity of the cosmic Microwave Background. The temperature of the cosmic microwave background differs by only a few parts in 100,000 across the sky. Compare this level of uniformity to that of the surface of a square table that is 1 meter on each side: How big would the largest bumps on that table be if its surface were smooth to 1 part in 100,000? Could you see bumps of that size on the table’s surface with your naked eyes?
