Scientists Measured All the Light Ever Produced in the Universe

Almost every point of light you see in the night sky is a star β€” a huge, broiling sun smashing atoms together to produce electromagnetic energy many light-years away.

Recently, scientists from Clemson University made one particularly awe-inspiring measurement: they figured out how much starlight has ever been produced in the universe. And it’s a very, very big number.
