One percent of your old TV's static comes from CMBR (Cosmic Microwave Background Radiation).
CMBR is the electromagnetic radiation left over from the Big Bang.
We humans, 13.8 billion years later, are still seeing the leftover energy from that event..
Cosmic noise, also known as galactic radio noise, is not actually sound, but a physical phenomenon derived from outside of the Earth's atmosphere.
It can be detected through a radio receiver, which is an electronic device that receives radio waves and converts the information given by them to an audible form..
This is because, before the first galaxies formed, the universe was opaque--it was a soup of subatomic particles that scattered all light.
But before the universe was opaque, the Big Bang happened, which is where the cosmic microwave background (CMB) comes from..

You can explore the strange "cold spot" in the cosmic microwave background in more detail with this article from Physics World and the UK Planck websitelets you browse the maps of the sky created by the Planck.
The universe began 13.8 billion years ago, and the CMB dates back to about 400,000 years after the Big Bang.
That's because in the early stages of the universe when it was just one-hundred-millionth the size it is today, its temperature was extreme: 273 million degrees above absolute zero, according to NASA.
Any atoms present at that time were quic.
The CMB is useful to scientists because it helps us learn how the early universe was formed.
It is at a uniform temperature with only small fluctuations visible with precise telescopes. "By studying these fluctuations, cosmologists can learn about the origin of galaxies and large-scale structures of galaxies and they can measure the basic parameter.
American cosmologist Ralph Apher first predicted the CMB in 1948, when he was doing work with Robert Herman and George Gamow, according to NASA.
The team was doing research related to Big Bang nucleosynthesis, or the production of elements in the universe besides the lightest isotope (type) of hydrogen.
This type of hydrogen was created very early .
