"The repeater may have created more questions than it delivered answers."
Difficult to understand as it is irregular with bursts at random intervals. "After 50 hours of seeing none during previous observations, the team now spotted them frequently, including, one time, a “double burst” of signals only 23 seconds apart."
Furthermore, the older FRBs were not seen to repeat, though given how short the signal is, it could have been missed in followup observations. It is quite possible that although these events all seem to be similar, they may have different origins or mechanisms.
That only happens when a range of telescopes point at a certain spot in the sky? It's possible, but by now they've likely ruled out most possible malfunctions.
These radio telescopes have a fairly narrow focus and when two telescopes located on different continents aim at a source several billion light years away, their focal points do not overlap anywhere near earth, so that rules out anything on or near earth. You could come up with a theory where it does originate on earth, but it wouldn't pass Occam's razor.
I (mistakenly) thought you were referring to faulty equipment at the FRB. As in someone opened the door of a galactic scale microwave oven analogue megaparsecs away.
And that sloppy engineering is still Occam's Razor no matter the scale or distance.
