Re: It's not aliens
I agree, it's not aliens.
I have a longer explanation I've given before as to why Radio Telescopes are great for science but not going to receive Alien transmissions, unless the Alien starship is nearer than the nearest star. Otherwise, we'll spot possible alien life or even their industrial pollution via spectrographic analysis. The James Webb should be a good addition for that search.
I look forward to someone figuring out what FRBs actually are. Though we likely don't want such a generator nearby. Some sort of magnestar is my guess.
An advanced civilisation doesn't even need FRBs for navigation. Pulsars are good for that and can even be used to navigate within our own solar system or the whole galaxy. The missing ingredient is a "starship". A generation ship is feasible but doesn't get the TV ratings.
