Roughly 3K, close to the temperature of liquid hydrogen. It was billions of K when it first escaped following the Big Bang roughly 13 billion years ago, but the universe expanded and cooledas well as Doppler red shifted it until it looks very cold now.
About 2.725 Kelvin.

It is important evidence of the Big Bang.
Technically, "cosmic rays" are high-energy particles rather than electromagnetic radiation. So no, they are not a type of light.
The 'big bang' theory.
It's hard to say. Can apples be compared to oranges? Cosmic rays are the "rays" that originate in the cosmos and strike earth. These cosmic "rays" are mostly protons with a few alpha particles and some token electrons. That makes the cosmic "rays" a form of particulate radiation. The gamma rays are the highest frequency (and highest energy) electromagnetic radiation (EMR) there is. This radiation is produced by changes in the nuclei of atoms. The gamma rays have very short wavelengths (and short periods), and they penetrate things well. The particles mentioned don't. Alpha particles have trouble moving through air. Electrons and protons can be stopped by a sheet of aluminum foil. Does that mean the gamma rays are more powerful? You make the call.
The evidence of cosmic microwave background radiation supports the Big Bang theory.
The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
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."
Cosmic background radiation provides important insights into the early universe, including its composition, density, and temperature. The presence of this radiation supports the theory of the Big Bang and helps explain the large-scale structure of the universe and the formation of galaxies. By studying cosmic background radiation, scientists can better understand the history and evolution of the universe.
3K cosmic background radiation refers to the microwave radiation that pervades the universe and has a temperature of approximately 3 Kelvin. This radiation is leftover from the Big Bang and provides important evidence for the expanding universe theory.
I would think it may be related to the temperature of the cosmic background radiation in degrees K.
the weakness of cosmic back ground radiation as those radiation are left over of big bangs
The lowest temperature ever observed in the universe is around 2.7 Kelvin (-270.45 degrees Celsius), known as the temperature of the cosmic microwave background radiation, which is a remnant from the Big Bang. It represents the average temperature of space.
Cosmic radiation External terrestrial and internal radiation
The leftover thermal energy from the Big Bang is known as the cosmic microwave background radiation (CMB). It is a faint glow of radiation that permeates the universe and is considered a remnant from the early universe when it was much hotter and denser. The CMB provides important clues about the early universe's properties and evolution.
Background radiation refers to the naturally occurring ionizing radiation that is present in the environment at all times, originating from sources such as cosmic rays, radioactive elements in the earth's crust, and even the human body. It is generally at low levels and is constantly around us.
The temperature of 2.7 Kelvin is significant in the study of cosmic microwave background radiation because it represents the remnant heat from the Big Bang, providing crucial evidence for the Big Bang theory and helping scientists understand the early universe's evolution.
