Cosmic Microwave Background Radiation - an overview

WebThe CMB radiation we are detecting today comes from regions of the universe that were about 13.8 billion light years away at the moment the CMB was emitted (those points are a lot farther away now). The fact that the Big Bang happened everywhere is a difficult conceptual issue for non-physicists. WebApr 11, 2024 · To track down the location of that dark matter, the more than 160 collaborators behind the National Science Foundation’s ACT located in the Chilean Andes focused on a quarter of the sky and closely observed microwave radiation emitted soon after the universe’s birth 13.7 billion years ago. clive laycock windows
