According to the cosmic background
The average temperature of the universe today, according to the cosmic background radiation.
Answer to Problem 13RQ
The temperature of the universe today is approximately
Explanation of Solution
According to the Big Bang theory, cosmic background radiation (CBR) is electromagnetic radiation. The region of the spectrum decides the type of radiation that is observed. One component of CBR is CBM, which is the cosmic microwave background. The Big Bang theory is evident from the discovery and detailed observation of CBM.
Absolute zero is the lowest limit of the thermodynamic temperature scale. It is the state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero Kelvin. The temperature of the universe today is approximately
This lower temperature calculation from the cosmic background radiation is very low and can compute how much our universe is wide. Many theories revealed that the universe is expanding, so the temperature of the universe is very low.
Conclusion:
Therefore, the temperature of the universe today is approximately
