Where can cosmic background radiation be found?

Answer 1

Cosmic Microwave Background Radiation has been discovered via WMAP mission and it is suggested that this has been left over from the Big Bang and galactic clusters are still moving away from each other at an ever increasing acceleration. WMAP's measurements played the key role in establishing the current Standard Model of Cosmology: the Lambda-CDM model. In the Lambda-CDM model of the observable universe, the age of the observable universe is 13.772 ± 0.059 billion years.

Answer 2

In 1946, George Gamow noted, that if the Big Bang Hypothesis was correct, then our Earth would be receiving isotropic microwave radiation with a spectrum resembling a black-body of temperature about 5 K. In 1964, two scientists found EXACTLY that type of radiation. Big Bang Cosmology explained it perfectly, all other ideas had no real explanation for it. In the "rules" of science, this meant BBC was correct and all other ideas were wrong.

Answer 3

It is believed that the cosmic background radiation was created at the beginning of the universe, thus they come from the of the universe. We can fell it on Earth, using telescopes.

Answer 4

It's all microwaves, with a spectrum exactly as predicted by the Big Bang Model sixteen years before they were detected.

Answer 5

The original discovery of the CMBR was done with a Dicke radiometer.
