It's amazing to think that the farthest away artifact that ever existed is one that people are in constant communication with, and there's only about a month or two round-trip communication time. Not really even the space part i'm talking about or the unimaginable distance, just how a couple hundred years ago exploration meant you had to send a bunch of guys off in a fleet of boats and you wouldn't know what they found until some of them return a year or two later (if at all).

It's not one month. Voyager 1 is 22h, 33m, 15s away, so it's about a 2 day round trip. https://voyager.jpl.nasa.gov/ https://voyager.jpl.nasa.gov/

What's even more amazing to me is that: - we can send a beam of EM radiation, of little power (like a cellular signal), - to communicate with an object billions of miles away, - through the vastness of space, - and the destination object is able to pick up the signal, - and vice versa.

  sincere question: How do you think about this evolution of our abilities within the the dark forest theory?

  Well, we need much more on our end than the power of a cellular signal- For instance, one of the support antenna dishes of the Deep Space Network is DSS-42 in Canberra... which is a 70 meter diameter parabolic dish. And the transmit power on our side is in the tens of kilowatts. Literally tens of thousands of times more power needed than a cell phone and directed by a 70 meter dish.... We need that because the dish on the Voyager probes is 'only' 3.7 meters. Still... not a cell phone antenna. That said, the transmit power of the Voyagers is tiny in comparison to ours and it is closer to that of the cell phone analogy- still more, however, at about 23 watts [1]. So, our end task of receiving that, by the time it gets to us, is damn impressive indeed I think.

    A rule of thumb with transmitter/receivers and gain over astronomical distances, is that the former Arecibo dish could have comfortably communicated with a stock cellular telephone on the moon, but not much further.

      Just so I can share this fact with other people too, do you have a source or calculation for this?
