Back in December, info on the signal that "appeared to be coming from Alpha Centauri but cannot" was leaked.
Shortly after we were told a paper about it would come "soon".
The signal was too good to be true, they said. And ss with Oumuamua, it was not Ayys because of reasons. But again, where is the paper and the explanation on its origin? If it was so clearly of human origin and a misunderstanding, why the delay?
