What’s Playing on Earth Tonight?

Via Strange Maps: "The first tv images of World War II are about to hit Aldebaran star system, 65 light years away. If there’s anybody out there alive and with eyes to see it, the barrage of actual and dramatised footage of WW2 will keep them shocked and/or entertained for decades to come."

    If I’m remembering my physics right, the signal would be so weak and distorted by cosmic radiation that it would be meaningless static by the time it reached Alpha Centauri. It’s an interesting idea, but I’m afraid there are likely no civilizations watching episodes of Ally McBeal in a nearby star system.

    um no yeek YOU’RE wrong and so is the person with the appropriate moniker above you. you obviously don’t understand the definition of coherence in this context and the fact that cosmic rays have nothing whatsoever to do with the propagation of radio waves in empty space. TV broadcasts from earth would be perfectly easily detectable from the nearest star systems with an arecibo scale dish. the calculations are trivial.
