American institutions collaborated on project that takes Chinese search for primordial gravitational waves ‘onto the ...

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

The South Pole Telescope has released its most precise image yet of the universe’s first light—the cosmic microwave background. This new ground-based data confirms cosmic expansion anomalies and ...

The Cosmic Microwave Background, also known as the earliest light of the universe, was captured through SPT-3G in the South Pole Telescope.

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the natural mass range of the WIMP would precisely match the abundances needed to ...

(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 ...

Scientists have achieved a groundbreaking feat by detecting a 13-billion-year-old microwave signal from the Cosmic Dawn using Earth-based telescopes in Chile. This discovery, made by the CLASS ...

The CLASS telescope array has taken a fresh look at the infant universe to hunt for polarized light in the Cosmic Microwave Background that resembles light bouncing off a cosmic car hood.

Key Takeaways The cosmic dawn, a period of time 13 billion years ago when the first stars were starting to form, is one of the least understood in the history of the universe. Light signals from 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.

The cosmic microwave background is the oldest light in the Universe, emitted about 380,000 years after the Big Bang. It corresponds to the moment when the Universe became cool enough for electrons and ...

In a recent paper published in EPL, Edward Wilson-Ewing, a mathematical physicist at the University of New Brunswick, Canada, explores the interplay between loop quantum cosmology and a phenomenon ...
