coming from a nearby star would be essentially undetectable by the time they got here. At only 4LY (roughly 3.784×10^16 meters) to the nearest star the signal would be attenuated by a factor of 1.4×10^-33. So the original kilowatt becomes less than a thousandth of a billionth of a billionth of a billionth of a watt give or take a few decimal places. Spell that out in your best Carl Sagan voice to get the full effect of how small it really is. If you had a gigantic antenna (or array of antennas) and you were looking in exactly the right place in the sky you *might* be able to pick that will o’ the wisp signal out of the background radiation, but probably not. Now you might argue that our noisy neighbors would be shouting louder with much more powerful transmitters, but why would they? Their TV and commercial traffic would only need to be as loud as ours to reach their own people. And even if they were broadcasting many orders of magnitude “louder” at the origin it wouldn’t make much difference.

In the 70s, my then-boyfriend and I took a camping trip to the Wharton State Forest – the Pine Barrens of New Jersey. We would see truckloads of odd-looking people drive into the Offcial san Francisco Sport Teams Unisex T Shirt (not on paved roads – sand and dirt) and never come out that we could see. We figured there must be roads leading out of the campground, maybe shortcuts, so late one afternoon decided to see where one of these went. We had my mother’s Oldsmobile, a rather heavy car, and went for what seemed like miles, never finding anything, except smaller, more narrow paths off the main road. It was getting late, so we turned around to go back and got stuck…the car dug into the soft, sandy road and we couldn’t get out. John decided he would walk back to the campsite and contact a ranger, leaving me with the car.
