Was cosmic microwave background radiation part of the Big Bang theory?

Yes. Cosmic background microwave radiation was the "smoking gun" for the idea of the Big Bang. Let's look. Jump with me.
As telescopes became more advanced and observers were more able to "see" the universe, it became apparent that things were moving "away" from earth and its environs. And the farther we looked and were able to see objects, the faster those objects were moving away from us. Simple. Now rewind the film. Things are getting closer and the universe is getting "smaller" as we roll back the clock. If we roll it back far enough, there was a time when everything was "smooshed together" before it went out and "apart" like it's doing. It must have "blown up" to get everything to end up going away from everything else, which it is. Big Bang theory. We good? Let's jump again.
There was a "big bang" and space-time was created and all this stuff began scattering like so much shrapnel from a bomb. The universe was "really small" compared what it is today, and all that matter and energy were crammed in there. It was hot beyond belief. The energy dispersed and matter began to form from the energy. Everything was still beyond the temperature in stars. But it was cooling. As the matter continued to form, the universe cooled more. Stuff spread out more and the universe got cooler and the cycle continued. Really high energy gave way to lower and lower energy, and eventually to the point where only an "afterglow" remained - microwave cosmic background radiation.
Big Bang was proposed way back in the 1920's. And the thinking was, "Gosh, if there was a big bang, what is left from the bang?" It wasn't until 1965 that a couple of guys from Bell Labs who were doing microwave experiments found this radiation. Point a microwave antenna in just about any direction and it's there, a little whisper or echo of the "blast" that was Big Bang.
Because of the big bang our universe was created.

The discovery of cosmic microwave background radiation and primordial helium gas was scientific evidence supporting what theory?
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?"
Which statements are true regarding the scientific evidence supporting the big bang theory?
Researchers found the "cosmic microwave background radiation", which is a heat imprint left over from the big bang. The redshift of light emitted by most galaxies indicates the universe is expanding.
What are two pieces of evidence of the big bang and that the universe is expanding?
1) Red shift seen in all distant galaxies, whose size is propotional to the galaxy's distance from us. 2) Existence, isotropy, and spectrum of the cosmic microwave background radiation.
What theory explains that universe began in a violent explosion?
The big bang theory does not actually begin with a "violent explosion." Instead, there was neither medium, light, nor sound in the initial moments. Instead, there was just a rapidly expanding ripple of rapidly cooling energy contained within a bubble of space-time. Eventually matter synthesized from this energy, crystallizing into hydrogen gas through which electromagnetic radiation could permeate. This radiation has been detected as the cosmic microwave background, or CMB. About that time the universe would have rung like a bell as sound energy would have propagated through it. We have detected sound waves bleeding energy off stars within sufficiently dense nebular, so we know this phenomenon is real, and interesting.
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
What is cmb?
CMB is cosmic microwave background radiation. It is the radiation that is the basis for the Big Bang theory.
The discovery of cosmic microwave background radiation and primordial helium gas was scientific evidence supporting what theory?
The 'big bang' theory.
Which theory of the universe did the 1964 discovery of cosmic microwave background radiation support?
I didn't check the year... But the cosmic background radiation is said to support the big bang theory, because it agrees with the radiation that is expected from an expanding Universe.
What evidence was used to develop the big bang theory?
The red shift and the cosmic microwave background radiation was the evidence used to develop the big bang theory.
Why was the COBE important to the big bang theory?
The COBE (Cosmic Background Explorer) was important to the big bang theory because it provided very precise measurements of the cosmic microwave background radiation. These measurements confirmed the existence of this radiation and provided strong evidence for the theory of the big bang, which suggests that the universe began with a hot, dense, and expanding state. The COBE's findings supported the idea that the cosmic microwave background radiation is a remnant of the early stages of the universe.
What are the 2 terms to support the big bang theory?
1) Cosmic Microwave Background Radiation 2) The universe is very quickly expanding
What theory predicted the cosmic background radiation?
The Big Bang.
What fact do all scientists believe provides evidence for the Big Bang theory Apex?
The cosmic background radiation - in the microwave part of the electromagnetic spectrum.
What discovery destroyed the steady state theory?
For most cosmologists, the refutation of the steady-state theory came with the discovery of the cosmic microwave background radiation in 1965, which was predicted by the Big Bang theory
How is the age of the Universe determined?
The age of the universe is determined by CMBR, which is left over energy from the Big Bang Theory. CMBR stands for Cosmic Microwave Background Radiation.
