The human era is theoretically the earliest possible epoch that allows astronomers to study the light from the origin of the universe. They can see that light clear back to 0.000028 of its present age. Because of the universe’s age, astronomers can directly view 99.9972 percent of cosmic history and almost behold the instant of cosmic creation. Astronomers’ analyses of maps of the radiation from that cosmic origin event have taught them more about its beginning, history, structure, and design than any other set of observations.
