In a practical sense right now, it is something that explains some anomalies in the shape of the gravitational waves of the event. We need to see better and more events to be sure about this.

Are they talking about gravitational wave echoes in this article?

All they are saying is: "Researchers from Caltech and MIT will convene for a press conference where they may announce that theyve picked up the tiny wobble of gravitational waves produced by two colliding black holes." which is extremely vague.


Thanks again,

Probably not. Despite the date of 10 March 2017, the article seems to be talking about the detection of gravitational waves last year. This started with rumors and then a press release. The detection was by LIGO which is operated by Caltech and MIT.

Ok thanks for the clarifications!
