Between the Very Large Telescope, the Extremely Large Telescope and the HMFTJC, somebody forgets about the absorptive properties of certain thicknesses of nickel-iron alloy; when they split the planet in half to build the WET, the architecture of the dish turns part of the spectrum to cosmic mush. Earth never realizes it’s missing the transmission of songs and speeches and TV Westerns from Wolf 359.
The Wolf 359ians, of course, have made the same mistake. They listen hard, so hard, but never get a whiff of AM or VHF–just the bloops of the kraken, mournful in the lonely deep.
