Cosmic microwave background radiation is a thermal radiation which fills our universe uniformly. Before the formation of stars and planets when universe was young, it was much smaller and hotter and filled with uniform glow of hydrogen plasma but As the universe expand it grew Cooler and when universe is cool enough electrons and protons form neutral atom then these atom No longer absorb thermal radiation and universe become transparent instead of being opaque fog and thus this theory explain the evidences of big bang that it's really a phenomena that creates everything that you see

How does expanding universe provide evidence for big bang theory?
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.
How does cosmic background radiation provide evidence for the Big Bang theory?
The Cosmic Microwave Background Radiation (CMBR) is an isotropic (to one part in 10,000) and continuous radiation from outer space, whose spectrum is identical to that of a blackbody at 2.7K . All of these absolute facts are easy to explain if one assumes Big Bang Cosmology to be true. Indeed, they were predicted by proponents of BBC 18 years before anyone looked for radiation from space. Nothing about CMBR -- not even its existence -- can be explained by any alternative to BBC. Those who deny BBC are reduced to stating, "I agree to the facts about CMBR, but I have absolutely no explanation for its existence, isotropy, or spectrum."
How was cmbr discovered?
The Cosmic Microwave Background Radiation (CMBR) was discovered in 1965 by radio astronomers Arno Penzias and Robert Wilson, who detected a persistent noise in their radio telescope that was uniform in all directions. Initially, they attributed the noise to various sources, including equipment issues and terrestrial interference. However, it was later identified as the remnant radiation from the Big Bang, providing strong evidence for the Big Bang theory. This discovery marked a significant milestone in cosmology, confirming predictions made by earlier theoretical work.
What sort of radiation suggested evidence for the Big Bang?
The existence, isotropy, and spectrum of the cosmic microwave background radiation (cmbr) is extremely easy to explain if Big Bang Cosmology is true; it is impossible to reasonably explain even its existence with any alternate cosmological hypothesis.
What is one piece of the big bang theory?
The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.

What does the big bang theory have to do with the universes expansion?
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.
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.

What penzias and Wilson did to find CMBR?
Arno Penzias and Robert Wilson discovered the Cosmic Microwave Background Radiation (CMBR) in 1965 while working with a sensitive microwave receiver at Bell Labs. They initially encountered a persistent noise that they couldn't attribute to any known sources, including their equipment or the Milky Way. After ruling out various potential causes, they realized that the noise was actually the remnant radiation from the Big Bang, providing strong evidence for the Big Bang theory. This groundbreaking discovery earned them the Nobel Prize in Physics in 1978.

Was and old theory resulted from the growing consensus within the scientific community as to the accuracy of the Big Bang theory?
Not sure about the intent of this question, but the Steady State Theory (an adaptation of Einstein's Static Universe Theory) was in contention with the Big Bang Theory in the early 1900s. For a while, support was split between these two theories. Eventually, the observational evidence, most notably from radio source counts, began to favor Big Bang over Steady State. There have been many other rival and alternative theories in spite of the consensus for th Big Bang Theory. While other ideas were proposed as non-standard cosmologies to explain Hubble's observations, including the Milne model and the oscillatory Universe (originally suggested by Friedmann, but advocated by Albert Einstein and Richard Tolman), the confirmed discovery and interpretation of the Cosmic Microwave Background Radiation (CMBR) barrier in 1964 secured the Big Bang as the best theory of the origin and evolution of the cosmos.
What are the thing that the big bang theory support?
The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.
What is the pictorial representation or sketch of the big bang theory?
Best pictorial representation of the Big Bang Theory is the extension of the Wilkinson Microwave Anisotropy Probe (WMAP) mapping of the Cosmic Microwave Background Radiation (CMBR) barrier, known online as the Graphical Timeline of the Big Bang.
How does the presence of CMBR support the big bang theory?
Basically, in that it closely agrees to what is expected from the Big Bang - this includes the existence of the background radiation, its approximate temperature, and its anisotropies. For more details, I suggest you read some more about the cosmic microwave background radiation - for example, you might start with the corresponding Wikipedia article.
