Based on this method, the sky will have a brightness of a 60W light bulb viewed from 2.5 miles away. It would be remarkably weak, but not entirely black.
Previous approaches relied on ultraviolet light from short-lived giant stars, but they were not so sure because they could miss the weakest stars. The blazer approach measures the light of every galaxy, even when it is otherwise too small to be detected. And while people are exploring the measurement of the inter-galaxy background light before, they tried to study the light directly and had to fight interference from the Milky Way.
This is not a completely accurate representation, at least not. In addition to that, the remaining 10 percent (important when covering the whole known universe), it does not include light that struck the dust and was redefined as infrared. Scientists, however, have become involved in that dust, and this may be just a matter of engaging older blazers to fill in more data. As it stands, the available information can now provide a much clearer picture of the formation of stars in the universe, including the frequency of new stars.
