"From the Ted Talk by Anil Ananthaswamy: What it takes to do extreme astrophysics"

Unscramble the Blue Letters

There is another way to search for dark matter, which is indirectly. If dark matter estxis in our universe, in our gaaxly, then these particles should be smashing together and purnciodg other particles that we know about — one of them being neutrinos. And neutrinos you can detect by the signature they leave when they hit water mucelleos. When a neutrino hits a water molecule it emits a kind of blue lihgt, a flash of blue light, and by looking for this blue light, you can eenssaillty understand something about the neutrino and then, ilinetrdcy, something about the dark matter that might have cereatd this nriutneo. But you need very, very large volumes of water in order to do this. You need something like tens of megatons of water — almost a gigaton of water — in order to have any chance of catching this neutrino. And where in the world would you find such water? Well the Russians have a tank in their own backyard.

Original Text

There is another way to search for dark matter, which is indirectly. If dark matter exists in our universe, in our galaxy, then these particles should be smashing together and producing other particles that we know about — one of them being neutrinos. And neutrinos you can detect by the signature they leave when they hit water molecules. When a neutrino hits a water molecule it emits a kind of blue light, a flash of blue light, and by looking for this blue light, you can essentially understand something about the neutrino and then, indirectly, something about the dark matter that might have created this neutrino. But you need very, very large volumes of water in order to do this. You need something like tens of megatons of water — almost a gigaton of water — in order to have any chance of catching this neutrino. And where in the world would you find such water? Well the Russians have a tank in their own backyard.
