摘 要:How old the Universe is, is one of the most curious questions. In modern cosmology, the age of the Universe refers to the time elapsed since the Big Bang. The current generally accepted age of the Universe is about 13.8 billion years, which is inferred from the cosmic microwave background (CMB)[1] by assuming a standard model of cosmology, i.e., Lambda-CDM model [2]. The uncertainty has been narrowed down to about 20 million years based on the CMB detections of the Planck spacecraft [1] and the Wilkinson Microwave Anisotropy Probe [3].
