We see white noise on the TV if the signal from one channel or another does not reach it. But what does this noise actually represent?
At first glance, white noise on TV is nothing interesting. However, in reality, this noise is radiation that reaches us from the moment when the universe was only 380,000 years old.
White noise is also popularly referred to as interference. It occurs if the TV has no signal for any reason. Usually, white noise is composed of terrestrial radio interference and the microwave background of the universe. It is this microwave background that is called the “echo of the Big Bang†or relic radiation.
