Cosmic Inflation: How Progress in Science Is Achieved

You may remember that about six months ago, scientists got all excited about the potential detection of ripples from the Big Bang -- direct evidence (if it were to be confirmed) for the event known as "cosmic inflation" (see e.g., "A Visit from the Big Bang,"). What happened then was that a team of scientists analyzing data from the BICEP2 telescope at the South Pole (Figure 1) claimed to have detected "B-mode polarization" -- an imprint in the cosmic microwave background that could have been created by gravity waves resulting from cosmic inflation.
