At the risk of oversimplifying, this is the lack of noticeably non-random fluctuations in the cosmic microwave background spectrum measured by Planck.

FORBES: Cosmic Inflation Model Gets A Boost From Planck Data

Biden sounded incredulous that Senate Republicans would consider blocking full consideration of legislation that matters to so many Americans, as demonstrated by polls that indicate overwhelming support across the spectrum for expanded background checks.

CNN: Reid to force a vote Thursday on debating gun proposals

Unlike my representatives, I had no staff to analyse them, no sense of their place in the spectrum of needs, and no understanding of the background and compromises that went into them.
