(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 ...

The superstructure "Quipu," recently identified, spans 1.3 billion light-years, challenging our understanding of the distribution of matter in space. This discovery, resulting from a study published ...

In addition, as early as 1964, the cosmic microwave background radiation was discovered, something that would prove the Big Bang theory, which predicted the existence of this radiation before the ...

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

Cosmic microwave background radiation In cosmology, cosmic microwave background (CMB) radiation (also CMBR, CBR, MBR, and relic radiation) is a form of electromagnetic radiation filling the universe.

The low-frequency cosmic microwave background Lindsay Oldham Research Highlights 17 Apr 2025 Nature Astronomy Volume: 9, P: 479 ...

The cosmic string problem arises because dark photons typically acquire their mass through a mechanism similar to how ordinary particles get mass—via interaction with a field called the dark Higgs.

By Ashley Strickland, CNN (CNN) — Astronomers have used mysterious fast radio bursts, or millisecond-long bright flashes of radio waves from space, to help them track down some of the missing ...
