Gravitational Waves Should Change How You See the World - The Atlantic

Every gravitational wave in that background the NANOGrav team found is humming through the very constitution of the space you inhabit right now. Every proton and neutron in every atom from the tip of your toes to the top of your head is shifting, shuttling, and vibrating in a collective purr within which the entire history of the universe is implicated. And if you put your hand down on a chair or table or anything else nearby, that object, too, is dancing that slow waltz.

… how awesome is this!
