Fermi paradox solution

This is in no way a scientific proper research, but I just needed to visualize my idea to why we cannot hear anybody. I made lots of assumptions about this, such as:

1. That every 10000 years or so, a sapient species in our galaxy discover and start using radio (Probably too often to be realistic...)

2. That they keep using it for 1500 years before inventing new forms of long range communication (like lasers) or keeping broadcasting in wide sprays instead of using more efficient tight beams. (our earth today emits less radio waves than it did in the past century, despite the intensity of communications only increased) and after that they stop using it either because they find something better, or they go extinct from (un)natural causes.

3. That radio signals can be detected at such distances as being artificial in origin (widely overestimated it, most likely, read somewhere that the radio waves from Earth become just noise due to static, interference and degradation at mere tens of light years away, and it completely stops being discernible in the radiation of our own sun after only one or two hundreds of light years)

4. There's some major unknown reasons preventing the "colonize all the galaxy" scenario in which the first aliens to arise begin to colonize whole galaxy, wiping out everybody else before they even learn how to use fire.

More realistic approach would likely to produced even more disconnected and deaf galaxy.

So the result is surprisingly solidly looking, compared to my concept of it. The galaxy is WAST, the light speed is SLOW, and the time scale of human lives is SHORT. We do not hear anybody out there, because there is not much chances that those we could hear would discover radio at the precisely right century and at right distance to be heard by us. Absolute most of the time Earth cannot hear anybody, despite this galaxy thriving with sapient life. And in remaining cases if we do hear somebody, we'd hear dead voices of somebody who was alive thousands of years ago, and is now likely to be gone one way or another.

I enjoyed reading the description. Thanks for the interesting video.

That doesn't take into account colonization or the Dyson Dillemma
