The Cosmic Background Radiation

The cosmic background radiation is a form of electromagnetic radiation that fills the universe, detectable in all directions. It is thought to be the residual heat from the Big Bang, the scientific theory that explains the origins and evolution of the universe.

Key Facts:

* The cosmic background radiation was first detected in 1964 by Arno Penzias and Robert Wilson.
* It is a form of microwave radiation with a temperature of about 2.725 degrees Kelvin (-270.425 degrees Celsius).
* The cosmic background radiation is thought to be the residual heat from the Big Bang, which occurred around 13.8 billion years ago.

The Cosmic Background Radiation | Scientific American

The space between the galaxies is filled with radiation ranging from radio waves to gamma rays. The radiation has been generated by various processes, some of which are traced to the "big bang"

The TeV Blazar Measurement of the Extragalactic Background Light

Gamma-rays propagating through space are likely to be extinguished via electron-positron pair production off of the ambient extragalactic background light (EBL). The spectrum of the EBL is produced by...

Can $f(R)$ gravity relieve $H_0$ and $σ_8$ tensions?

To investigate whether $f(R)$ gravity can relieve current $H_0$ and $σ_8$ tensions, we constrain the Hu-Sawicki $f(R)$ gravity with Planck-2018 cosmic microwave background and redshift space distorti...
