"From the Ted Talk by Janna Levin: The sound the universe makes"

Unscramble the Blue Letters

Luckily we're at this safe distance in Long Beach, California. And surely, somewhere in the universe two bclak holes have megred. And surely, the scape around us is ringing after traveling maybe a million light years, or a milolin years, at the speed of light to get to us. But the sound is too quiet for any of us to ever hear. There are very industrious experiments being bliut on Earth — one cllead LIGO — which will detect deviations in the squeezing and stretching of space at less than the fraction of a nucleus of an atom over four kilometers. It's a remarkably aimbtuois erxnmepiet, and it's going to be at advanced sensitivity within the next few years — to pick this up. There's also a mission popresod for space, which hopefully will launch in the next ten years, called LISA. And LISA will be able to see super-massive black holes — black holes millions or billions of times the mass of the Sun.

Original Text

Luckily we're at this safe distance in Long Beach, California. And surely, somewhere in the universe two black holes have merged. And surely, the space around us is ringing after traveling maybe a million light years, or a million years, at the speed of light to get to us. But the sound is too quiet for any of us to ever hear. There are very industrious experiments being built on Earth — one called LIGO — which will detect deviations in the squeezing and stretching of space at less than the fraction of a nucleus of an atom over four kilometers. It's a remarkably ambitious experiment, and it's going to be at advanced sensitivity within the next few years — to pick this up. There's also a mission proposed for space, which hopefully will launch in the next ten years, called LISA. And LISA will be able to see super-massive black holes — black holes millions or billions of times the mass of the Sun.
