In 1946, George Gamow noted that, if the Big Bang had happened as Georges LeMaitre had hypothesized, our planet would be receiving isotropic microwave radiation with a spectrum like that of black body radiation from a 5 K source. Later refinements have shown that it would resemlbe BBR from a 2.7 K source.
What we see is exactly as predicted. No other cosmologizl hypothesis can explain this CMBR except to say, "It's just there and I have no explanation for it."

ViviThe Cosmic Microwave Background (CMB) radiation is considered a key piece of evidence supporting the Big Bang theory because its uniformity, temperature, and energy distribution match the predictions of the theory. The CMB is understood as the remnant radiation from the early universe, believed to have been released about 380,000 years after the Big Bang. Its discovery in 1965 provided important confirmation for the idea that the universe began with a hot, dense state and has been expanding ever since.

What has static got to do with the big bang?
In the context of the Big Bang theory, the "cosmic microwave background radiation" was once thought to be static, leading to the discovery of the Big Bang. Static noise interference inadvertently discovered by Arno Penzias and Robert Wilson in 1965 turned out to be the afterglow of the Big Bang, providing strong evidence for the theory.
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.
What is the cosmic micorwave backgrounds orgin?
The cosmic microwave background (CMB) originated about 380,000 years after the Big Bang as the universe cooled enough for protons and electrons to form neutral hydrogen atoms. This allowed photons to travel freely, creating a snapshot of the early universe that we can observe as the CMB today.
What kind of radition helped prove the big bang theory to scientists?
The discovery of the cosmic microwave background radiation (CMB) played a critical role in confirming the Big Bang theory. This radiation provides strong evidence supporting the idea that the universe originated from a highly compact, hot state and has been expanding and cooling ever since.
What does cmb stand for?
CMB stands for Cosmic Microwave Background. It refers to the faint radiation left over from the Big Bang that fills the entire Universe.
