What I don’t get is why we are expected to see visible signs in some spectrum or another from other galaxies in this tiny window of time our tech represents. All this says is nobody is close, or was close when some signal may have left it’s destination. 10,000 light years away=10,000 years ago for it’s transmission.

if a thousands of such civilizations came up at any time in our human era, they are invisible to us for millennia to come. Whole epochs perhaps.

Maybe at any given time there is a bare handful in any particular galaxy. And those not close to one another by any rational measure.

Of course metastability could be the terrifying answer. Everyone that becomes visible gets wiped out by a stealthy xenophobic civilization. Deep sky radar search anyone?
