Inflation

(a) Why is it puzzling that the observed CMB temperature is almost exactly the same on opposite sides of the sky? How would this result be explained in cosmology theories that do not include inflation?

(b) How does inflation answer the puzzle from part (a)? What other properties of the homogeneous universe does inflation explain?

At the time of recombination (z = 1100), the largest CMB temperature fluctuations (hot spots and cold spots) were 380,000 lightyears in size. What size (in Mpc) are these CMB fluctuations today (1 Mpc = 3.1 × 106 lightyears)? Write two or three sentences about how this size compares to the sizes of galaxy clusters today (which are around 100-150 Mpc in size) and what the connection is between the CMB fluctuations and galaxy clusters.

For every trial, the waves travel for exactly the same amount of time to the same point from each of the speakers. Does't that mean every "Wave state" should be a "trough?" Explain. What is the essential difference between your data focused on the destructive interference and the data focused on the constructive interference?
