Cosmic microwave background is a sea of radiation that provides us with evidence for the big bang. When around 1916 Einstein first used general relativity to build a cosmic model, he followed the ...

We analyze in Chapter 5 the smoothing of the primeval temperature fluctuations throughout an "encroaching" cosmic background, causing photon-to-baryon ratios to increase, overall, and become highly ...

The cosmic neutrino background (CvB) has been posited for years but has yet to be found, primarily because neutrinos are notoriously difficult to detect. Now, a paper from Professor Douglas Scott ...

Scientists investigate gravitational wave memory theory by Einstein, searching for traces in the cosmic microwave background.

This Cosmic Microwave Background Radiation (CMBR) is the conclusive evidence for the Big Bang theory. The 'temperature' of deep space has been measured as around 3K, not absolute zero, due to the ...

One of the best ways to observe this era is with low-frequency radio telescopes, which can observe the “spin-flip” radiation from the hydrogen that pervades the Universe during the Cosmic Dawn.

Further evidence for the Big Bang comes from the discovery of cosmic microwave background radiation (CMBR). Astronomers discovered cosmic microwave background radiation in the 1960s. The ...

Nasa launched the $488 million Spherex space telescope on Tuesday to map the entire sky and understand galaxy formation and ...

A deep-sea detector glimpsed a particle with 220 million billion electron volts of energy — around 20 times as energetic as any neutrino seen before.

In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion ...
