Cosmic Microwave Background
1 reportCosmic Microwave Background is an astronomical phenomenon recognized by characteristic signals, timescales, energy scales, and source environments. Current understanding relies on last scattering surface and recombination epoch, with uncertainty tracked across measurement, classification, and reconstruction.
A source-based view of Cosmic Microwave Background considers foreground removal, while also considering cosmological parameter fits and early-universe models. The account anchors early-universe models in instrument calibration and uses population statistics to test whether the pattern extends beyond one dataset; the conclusion remains provisional because selection effects and uncertain source distances can alter inferred rates or energies.

High Energy Photon From Distant Gamma Ray Burst Challenges Physics Limits
A photon with record-breaking energy from the gamma ray burst GRB 221009A reached Earth despite theoretical barriers. New analysis suggests a possible explanation involving axion-like particles and Lorentz invariance violation
