And yes, it's brighter than anything you've ever seen: This light floods every cubic centimeter of the cosmos, including the Earth! Paradoxically, the brightest things in the universe exist only because of the darkest things in the universe – black holes. That single event, that transformational epoch, released more photons than every star that has ever burned in 13 billion years. Visit our corporate site. Bath 520-626-4402 By Tech Explorist. The Sunâs close proximity to Earth is why it looks like the brightest thing in our sky. Astronomers also will use the Atacama Large Millimeter/submillimeter Array, and eventually NASA’s James Webb Space Telescope, to look within 150 light-years of the black hole to directly detect the influence of the black hole's gravity on gas motion and star formation in its vicinity.
