Dropping the Physics
A portion of the salt and pepper you see on an analog television actually comes from the radiation left over from the Big Bang. The radiation, known as the cosmic microwave background, permeates all of space and gives the universe an average temperature of 2.7 K (-455 degrees F), just slightly above absolute zero.  The first detection of the microwave background was made in 1964 at AT&T Bell labs where physicists initially thought that an accumulation of bird droppings on their 20-foot antenna was the source of the unwanted noise signals. The Nobel Prize in Physics was awarded for the accidental discovery which supported the now prevailing Big Bang Theory.
