The big bang caused the background radiation.
the weakness of cosmic back ground radiation as those radiation are left over of big bangs
Primordial background radiation is in actuality Cosmic Microwave Background. To discover just what Cosmic Microwave Background theories are, visit the URL posted below:http://www.astro.ucla.edu/~wright/CMB.html
Natural background radiation
cosmic microwave background radiation.
The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
The cosmic background radiation was discovered in 1964 by American radio astronomers Arno Penzias and Robert Wilson
Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.
The radiation left over from the big bang is found in the microwave region of the electromagnetic spectrum. As the universe expanded and cooled, the intense hard gamma radiation that existed became radio waves in the low gigahertz region, characteristic of a temperature around 30 Kelvin.

1965.
The evidence of cosmic microwave background radiation supports the Big Bang theory.
