It shows that at the beginning of time all radiation was trapped in a small place and since the universe has expanded and cooled so has the radiation which is why it has dropped from very high radiation to its fairly low microwave radiation state. Today. It is the afterglow of the universe which heavily backs up the big bang theory.
The energy of the cosmic microwave background is about 400,000 times less than the energy of all the stars and galaxies that ever existed. The CMB is the remnant radiation from the early universe, while the energy radiated by stars and galaxies have been accumulating over millions of years.
The Planck telescope was launched on May 14, 2009. It operated for about four years, until October 23, 2013, collecting data on the cosmic microwave background radiation.
Not sure what you mean by "theory" and not sure what you mean by "pros and cons." The MCBR (actually the "CMBR") exists, and its spectrum is EXACTLY as predicted by the hypothesis of our Universe having begun to expand from great density about thirteen billion years ago. Proponents of every other hypothesis about our Universe have to state, "I don't know WHY the CMBR is there, and I don't know why it has the spectrum it has. It's just there and I can't explain it."
The Cosmic Microwave Background Radiation was predicted by proponents of Big Bang Cosmology (BBC) about 18 years before it was found. Its existence, isotropy, and spectrum is easy to explain with BBC; pretty much impossible to explain using alternatives.
Cosmic microwave background radiation was predicted by Big Bang Cosmology about 16 years before the former was discovered -- by accident. The existence, isotropy, and spectrum of CMBR are all exactly as predicted by BBC, and all alternatives to BBC are reduced to stating, "It's just there and there is absolutely no explanation for it."
None, background radiation is the natural radiation present all around us and has been for thousands of years.

Microwave photons from the cosmic microwave background radiation have been traveling through space for approximately 13.8 billion years, since the early universe.

The cosmic microwave background (CMB) originated from the hot, dense state of the early universe about 13.8 billion years ago. It is the afterglow of the Big Bang and provides crucial information about the early universe, such as its temperature, composition, and density fluctuations. This radiation helps scientists understand the evolution and structure of the universe.
Radiation has existed on Earth since its formation around 4.6 billion years ago. Natural sources of radiation, such as cosmic rays from space and radioactive elements in the Earth's crust, have been present since the planet's early days. Early life forms evolved mechanisms to cope with this background radiation.

The Big Bang is estimated to have occurred around 13.8 billion years ago, based on observations and measurements of the universe's expansion and the cosmic microwave background radiation.
The earliest time in the universe that we can directly observe is the cosmic microwave background radiation, which dates back to about 380,000 years after the Big Bang. This radiation provides a snapshot of the universe at that time, when it cooled enough for atoms to form and light to travel freely.
