How cosmic microwave background radiation shows us the universe is changing?
Cosmic microwave background (CMB) radiation is a remnant of the early universe, a faint glow left over from the Big Bang. By studying the CMB, scientists can determine various properties of the universe, such as its age, composition, and rate of expansion. Over time, the CMB has cooled and stretched as the universe expanded, and analyzing its temperature fluctuations provides insights into the evolving structure and dynamics of the universe. Therefore, the CMB radiation serves as a powerful tool to understand how the universe has changed and evolved over billions of years.
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."
What is the background noise of the big bang theory?
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.
Is radiation generated by the big bang cooled and now is detectable as microwaves?
Yes, that is correct. The radiation generated by the Big Bang is called the cosmic microwave background (CMB). As the universe expanded and cooled over billions of years, the high-energy radiation transformed into lower-energy microwaves. Today, the CMB is detected as a faint glow of microwaves that permeates all of space and provides crucial evidence for the Big Bang theory.
Where can cosmic background radiation be found?
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.
How does cosmic backround radiation differ from the big bang?
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."
What dangers does background radiation pose to humans?
None, background radiation is the natural radiation present all around us and has been for thousands of years.

What is another explanation for the cosmic microwave background?
This is the another theory, which may explain the cosmic microwave background.About 14 billion years ago, you had the "Big bang". Then you had the matter in the form of plasma for about 380,000 years. Till then light was absorbed in your universe. When the matter cooled down enough, light entered in your universe. The cosmic microwave background is in the form of "Glow". That means you are unable to locate the source of light. Cosmic microwave background is not associated with any stars or galaxies. Such type of glow light indicate that the rays are practically parallel. That means the lens of your space telescope perceives the radiation as parallel radiation. So the source of radiation is probably too far, for the astronomical scale also. So the radiation has been coming from other universes, which are too much away from your universe. You may be able to locate the source of radiation with twin space telescopes placed at Lagrangian points 4 and 5. The light is "red shifted" to microwave radiation, means that it has come through the areas of very high gravitational force. The radiation has been coming from all sides means that there are too many sources of light around your universe.
How did the earth come to be before the radiation of the big bang traveled here?
If you are referring to the cosmic background radiation that pervades all space with an ideal blackbody temperature of 2.7 degrees Kelvin, the earth formed long afterwards. The universe began as a hot, dense, inflationary expansion of "energy" 13.7 billion years ago. Our earth is 4.6 billion years old. The difference is 9.1 billion years.

How old is light energy?
The light that is now coming to us in the cosmic microwave background radiation was released in an event called "Recombination," which occurred about 377,000 years after The Big Bang, which occurred about 13.7 billion years ago. Thus, for SOME light beams we detect today, our Universe is about 13.7 billion years old.
Is radiation generated by the big bang cooled and now is detectable as microwaves?
Yes, that is correct. The radiation generated by the Big Bang is called the cosmic microwave background (CMB). As the universe expanded and cooled over billions of years, the high-energy radiation transformed into lower-energy microwaves. Today, the CMB is detected as a faint glow of microwaves that permeates all of space and provides crucial evidence for the Big Bang theory.
Why do radiation detectors register counts even though no apparent source of radioactivity is in the area?
Radiation detectors register counts even though no apparent source of radioactivity is in the area due to the background radiaoactivity and radiation that is always present. There are high energy cosmic rays (gamma) from the Sun, low level alpha, beta, and gamma from fallout from various nuclear detonations and accidents over the years, decay processes from naturally occurring Uranium, radiation coming from our own bodies, in the form of Strontium, Cesium, Potassium, and others, and contamination processes that occur in power and processing plants. When building and calibrating sensitive detectors, we always measure the background radiation and subtract that from the measured results.

How has cosmic background radiation helped us determine the age of the universe?
The CMBR did not reveal anything DIRECTLY about the age of our Universe. However, its spectrum and isotropy are almost perfectly as predicted by a Universe that began to expand about thirteen billion years ago -- a timeline given by the Hubble Constant. As such, it gives extremely strong support to that timeline.
