Default What Are Extraterrestrials Watching?
In article ,

********.
Lensing more noise/weak signal does not change the ratio,
and does not make for better reception.
And your lensing works only over millions of light years.
Which leaves you micro-micro-micro watts of received power.

I take your point about the scale over which lensing works. But why is
the effect not similar to using a high-gain aerial, which is common
enough?
