It follows logically from what we know about physics that the expansion of the universe from a hot and dense state should produce a remnant of microwave radiation. Reasoning from the Big Bang model (particularly the LCDM model), it is also possible to work out the intensity (temperature) of that radiation, and the nature, size and distribution of variations in that radiation. Detailed observations of the night sky have confirmed these predictions to a remarkable degree.
What else can I help you with?
What are two pieces of evidence that support the Big Bang theory?
Hubble's discovery in the 1920s of a relationship between a galaxy's distance from Earth and its speed; and the discovery in the 1960s of cosmic microwave background radiation.
Which theory is supported by the evidence of cosmic microwave backround radiation?
The evidence of cosmic microwave background radiation supports the Big Bang theory.
Why the cosmic background adiation was an important discovery?
It helped prove the big bang theory.
How ia cosmic background radiation related to the big bang theory?
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.
Which theory of the universe did the 1964 discovery of cosmic microwave background radiation support?
The 1964 discovery of cosmic microwave background radiation supported the Big Bang theory of the universe. This radiation is considered a remnant of the early stages of the universe when it was hot and dense, aligning with the predictions of the Big Bang model.

Hubble's discovery in the 1920s of a relationship between a galaxy's distance from Earth and its speed; and the discovery in the 1960s of cosmic microwave background radiation.
What theory predicted the cosmic background radiation?
The Big Bang.
Which theory is supported by the evidence of cosmic microwave backround radiation?
The evidence of cosmic microwave background radiation supports the Big Bang theory.
Which of these is evidence that supports the big bang theory?
cosmic microwave background radiation
Why the cosmic background adiation was an important discovery?
It helped prove the big bang theory.
This theory lost its appeal when astronomers discovered quasars and cosmic background radiation?
In Cosmic Physics for $1000, Alex, "What is the Steady State Universe?"
The discovery of cosmic microwave background radiation and primordial helium gas was scientific evidence supporting what theory?
The 'big bang' theory.

Which theory lost its appeal when astronomers discovered quasars and cosmic background radiation?
The steady state theory lost its appeal when astronomers discovered quasars and cosmic background radiation. This theory posited that the universe was eternal and unchanging on a large scale, but the detection of quasars indicated a dynamic universe with active galactic phenomena. Additionally, the discovery of cosmic background radiation provided strong evidence for the Big Bang theory, suggesting a specific origin point for the universe's expansion, contrary to the steady state concept.
What discovery destroyed the steady state theory?
The discovery of the cosmic microwave background radiation in 1965 by Penzias and Wilson provided strong evidence in support of the Big Bang theory, contradicting the predictions of the steady state theory. The steady state theory proposed a continuous creation of matter to maintain a constant density of the universe, but the presence of the cosmic microwave background radiation was better explained by the rapid expansion and cooling of the universe after the Big Bang.
What scientists use to support the big bang theory?
The Doppler effect and background cosmic radiation are the big ones.
