There’s so many “holes” & “what ifs” related to this study that it is just barely worth reading about...
Frequency/wavelengths evaluated?
What if messages are being sent to us via drumbeat?
What range of the distant past does this data represent?
Will they repeat the every 1000000 years from now and update us?
I’m still waiting...
Also, what did they do with the thousands of hours of SETI data my computers acquired and sent to them?
Bingo!
