If Humans simply disappeared one day...
Okay, the cosmos are anything but empty space. There are solar flares, solar wind, gamma rays, and the like, which are not background radiation from the Big Bang. Hell, a major problem which satellites and deep space probes face is electro-magnetic interference.

F.06 How far away could we detect radio transmissions?OK, how strong is that signal by the time it reaches our putative alien audience at 55 light-years distance? Not very. The megawatt broadcast washes over ET's world with a power density of about 0.3 million million million million millionths of a watt per square meter, which is not exactly a scorching signal.
TV Beacons in Space - TIMEEven a 3000 meter diameter radio telescope could not detect the "I Love Lucy" TV show (re-runs) at a distance of 0.01 light years! It is only the narrowband high intensity emissions from Earth (narrowband radar generally) that will be detectable at significant ranges (greater than 1 LY).
(200 light years is still a far cry from trillions of light years)Sweeping the Universe. Unlike low-frequency radio waves, which are reflected back by the earth's ionosphere, UHF transmissions continue traveling in a straight line out into the farthest reaches of space. And unlike standard television waves, which penetrate into space but tend to be drowned out by cosmic radiation of about the same frequency, UHF broadcasts could eventually be detected as far off as 200 light years from earth.
Once again, narrowband transmissions pointed in one specific direction can travel great distances, but broadband television signals transmitted today will be dead before you die.

Sounds like you know what you're talking about

So............ you're telling me that the old shitty signals that you can barely pick up on your tv are stronger then the satelites?

If humans disappeared then that would leave me with all the weed and no 12 year olds running around in jap cars with black disco music blaring at deafening levels.
I say it would almost be heaven.
Except for no pussy of course.lol But then I could get a dog.

I don't even know where to start on everything wrong with that.

i read that same article, it was in TIME or Newsweek or something...
it was a fantastic read, i love learning about those hypothetical situations. kinda scary.I mean, if a trooper sees a joint in my hand, and i\'m at the wheel of a car, i\'m busted... but for some reason, I never get pulled over for eating too many candybars...
