The standard model of cosmology relies on an accurate reading of the cosmic microwave background. This radiation, emitted 380,000 years after the Big Bang, is considered proof of the theory's ...

The Earth might be near the center of a vast low-density void in space, which could explain one of the cosmos's greatest ...

The cosmic microwave background (CMB) is the oldest light in the Universe, emitted approximately 380,000 years after the Big Bang. It is microwave radiation that uniformly fills space, ...

For centuries, people have looked to the stars, asking how it all began—and how it might end. Now, thanks to a bold new study ...

Astrophysicists suggest our galaxy may lie inside a "cosmic void" - offering a new explanation for the universe’s conflicting ...

Fresh evidence claims that the Earth and the surrounding galaxy are suspended inside a cosmic void based on echoes from the ...

Evidence is mounting that cosmic dark energy, long thought constant, may weaken with time - potentially altering the fate of ...

New observations support the idea that hot, diffuse threads of gas called cosmic filaments connect clusters of galaxies ...

The cosmic microwave background — the leftover light from when the universe was only 380,000 years old — soaks the entire cosmos, filling every cubic centimeter.

(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...
