Radio waves started emitting from the Earth 122 years ago, in about 1902.
That is 63240.87 astronomical units. You figure out the miles. Under the "Contact" scenario, we have been announcing ourselves to the universe for that long. There is a sphere 244 light years in diameter that has the possibility of "hearing" us. How many stars are in that sphere? How many have habitable planets? How many of those planets are inhabited? How many of them have LOOK (Life Of Our Kind*) inhabiting them? Life Of Our Kind means living organisms capable of communicating with us. I'm not interested in fungus balls, I want alien organisms... green skinned ones, preferably. |

Our radio waves that far out are likely indiscernible from background noise.
Then you have the distinct possibility that we don't really want them to know we are here |

Here is the thing....
For any lifeforms out there that can receive our signals, and decode them. I figure it goes like this. Alien 1. Hey we got a signal!!!!! Alien 2. What number is it coming from? Alien 1. Earth. Aliens 2 and 3. It is a spam call. Ignore it and put it on the block list. All they want to do is sell us fake shit, take our hard earned resources and limit our freedoms. I wish they would put in as much time to expanding freedom, let people keep what they earned, and stop scamming each other, as they do with all their B.S. Alien 1. Hey Marvin. How it that earth death ray coming? |

Quoted: Our radio waves that far out are likely indiscernible from background noise. View Quote I think that's very likely, and the inverse square law is a harsh mistress. It's not like we're deliberately broadcasting as powerful signal as we can into space in as many directions as possible. Whatever radio signals are inadvertently being broadcast (or "leaking" out) are at very low power, and diminishing dramatically over distance. So it's not like some alien civilization would suddenly be drowning in our radio signals when they are theoretically within range. They'd have to be looking for it, with insanely sensitive detectors, IMO. I think the whole "our radio signals are reaching this far" thing is mostly a theoretical observation, and likely not something with any real implications. Then again, if we are making assumptions about alien technology, who knows how sensitive it could be, and what might be detected? If some advanced alien civilization had their own SETI program and had really sophisticated tech, I guess anything is possible. ... I just don't think it's plausible or likely. |

Quoted: And yet, here you are. View Quote It's a reflection of how most people think about these things. Either they don't think about alien life at all, in any context. Or aliens are snootier than the most pretentious Ivy League graduates and their only possible interest in humanity is hunting us for sport. Probably an inevitable result of decades of science fiction tropes. It just gets annoying when you see the same story over and over and over and over again. |

How faint would the radio signal be at 244 light years?
After an AU or 2, I be it's mostly background noise... do radio waves suffer redshift? If so, even less likely to hear us. |

How come we have never received any communication from anyone not from this planet?
We have sent out billions of transmissions. |

Just a point of fact.
The inverse square law forces a radio signal into the noise floor very quickly but the signal is still detectable and usable. This is done all of the time in communications. I took “Stochastic Processes with Random Signals” and “Electromagnetic Fields and Waves” the same semester. Fun math. |

5.8 trillion miles traveled in 122 years give or take.
Speed of light is calculated to 669 million miles per hour and Is 5.8 trillion miles in distance. So the earliest signal would’ve traveled 1 light year by now. With all the space, TECH and telescopes that we haven’t satellites, we should be able to pick up something within that area by now |

And how powerful were the radio signals broadcast from this planet a century ago?
To think they have somehow traveled intact as far as light speed would allow over that time is the stuff of science fiction/fantasy. |

As noted, the Inverse square law is a bitch.
There's also the issue of frequency v. distance, and what can actually leave Earth's ionosphere. Then there's that terrestrial ground-based stations only broadcast to roughly (minus a tad) 180° of sky, and their power is either omnidirectional, or horizontally polarized for terrestrial relievers. So the "200+ light year diamater sphere of expanding radio broadcasts," besides being weak as fuck, it's blobby and irregular as hell, and besides being nothing remotely optimized for interstellar communication, from any individual point on that sphere, or the later signals flowing outward within it, they're also very random, short duration, & intermittent. For a civilization with "higher technology" we're discussing something like, a civilization within that 200 light year RF bubble Earth has created, they would need to Dyson swarm their system with ultra sensitive radio recievers and operate them all as a giant interferometer array. And that begs the question of why they didn't notice Earth was "interesting" with atmospheric biosignatures for robust life, thousands, or millions of years before they started detecting our incredibly faint technosignatures? Something WE are starting to look for with the JWST... Out to about 1000-1500 light years or so. The simple answer is because they aren't there. The "Fermi Paradox" is a terrible shit-tier thought construct. It isn't even a "paradox." It's really just a bunch of faulty epistemological bullshit whining about: "The situation as it just simply is." If one tries any criteria with some semblance of rigor, instead of useless subjective crap, even just accounting for the vast amount we don't know as variables, or how many important factors there even are as a variable... You may not get "the odds" of there being any technological civilizations around, or how close they are, but you do get n-power law curves that demonstrate with decent rigor, at least what the "odds of different odds" are. And the "odds of the odds" all tilt exceptionally high, to the "odds are insanely low." We may not be truly "alone" in the Universe, but it's extremely likely, like "bet your house, salary, & kids on it"-good that we are almost certainly "functionally alone." As in, so far away, that if they were an advanced galactic civilization that does Kardashev Scale mega-engineering things so big we could one day see it, the light from their galaxy could have left before the dinosaurs, and still take a few dozen million more to get here. Or, the expansion of the Universe drags us and our light apart that we never ever see each other. Essentially, to even get halfway decent odds better than 100:1 that we even see very distant technosignatures, humans, or maybe ChatGPT if it kills us all, will need to persist for 500 million/.5 billion years. Or, just uplift whatever pond scum we find more locally, and watch to see how it turns out. Then being verrrry patient, waiting to decide if any: "Hey guys, try banging those rocks..."-type of assistance is needed. There's no "zoo" and no "dark forest," and while we may indeed extinct ourselves doing something stupid, nothing in the Fermi Paradox points to it being "inevitable." Nor does "answeing the Fermi Paradox" credibly do anything like suggest: "They're already here & .gov is hiding it." As it's all just double-bullshit, built on a foundation of the original Fermi Paradox bullshit. |
