Where The Universe’s Light Come From
The majority of us undoubtedly imagine space to be gloomy. Thanks to the far-off stars, it appears to be mostly dark. However, there is a lot more light than you might initially believe, and as of yet, we don't know why.
A few years ago, the NASA New Horizons spacecraft departed from our solar system and began traveling into space. In order to see how brilliant the universe actually was, NASA tried to block out all known light sources while traveling. Half of the ambient light remained in the end, all of it coming from unidentified sources.
It's possible that the light is merely an optical illusion and that New Horizons only noticed it as a result of a technical glitch. It's also feasible that the universe is simply extremely luminous for unexplained causes. In any case, as far as we currently know, half of the universe's light comes from an unknown source.
