White noise






So, the white noise is caused by photons emitted by Big Bang.
These neutrons and electrons have been cooled down throughout eras, forming atoms. But these photons are still too hot to settle down, moving randomly in the air. Thus, TV aerials catch these photons and show white noise on the monitors of TV.

In terms of it, TV is the machine to translate the random movements of photons into a graphical representation.

It's quite interesting that this mundane object shows a small segment fascinating history of the universe.
