The universe has been making stars for a good 13 billion years or so, and a natural question to ask might be “how many stars have existed in that time?” But now astronomers have taken it several steps further and asked “how much light has been emitted in that time?” Using a new measurement method, the team has apparently managed to quantify all the starlight every produced in the observable universe – and the result is a figure that’ll make your eyes water.

Physicists have created atomic clocks so precise that they can measure deformations in spacetime itself, according to new research.
We don’t all experience time passing equally—time passes more slowly closer to something massive’s gravitational pull, as famously theorized by Albert Einstein. And since gravity is typically interpreted as the way mass warps space itself, that means a precise-enough atomic clock could serve as a scientific tool for measuring how objects change the shape of their surrounding space.
