The echoes from inflation could still be shaking the cosmos today

  The inflation is transitory

  [More recent work has seen pulsar timing arrays (PTAs) such as NANOGrav successfully identify a specific flavor of gravitational wave known as the stochastic gravitational wave background (SGWB). The SGWB is similar in concept to the cosmic microwave background—a consistent glow from the early universe that astronomers can see as a series of microwaves coming from all directions at once.]

  First time I’ve heard of this concept.

  Perfect timing, as just this past week I’ve been wondering about these low-frequency gravitational waves that were announced with a splash last summer, then I heard nothing, that is until now.

  It takes a while to go through the data and find specific parameters you’re looking for. This is radio astronomy, using data from antenna telescopes all over the world. For comparison in a similar type of project, it took two years to crunch the numbers from the Event Horizon Telescope and resolve a fuzzy image of the supermassive black in M87.
