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 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 ...

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 ...

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the ...

A never-before-seen image of the cosmic microwave background, combining data from the Atacama Cosmology Telescope (ACT) and the Planck satellite, offers a high-definition view of the early ...

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

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

(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 ...

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

This afterglow—the "cosmic microwave background" (CMB), the relic radiation left behind by the Big Bang—has given astronomers insights into the birth of the universe and helped shape the ...

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.

New research presented at the Royal Astronomical Society's National Astronomy Meeting (NAM) in Durham suggests a revolutionary possibility: Earth and the entire Milky Way galaxy might be nestled ...
