Is this pic true?
Oh my creator of matrix what a hell are we even hoping for if our radio waves only went so far in our own galaxy?

Also when you imagine that the stars we see in the sky are the stars that are actually only in a small circle around our part of galaxy... jesus fuck

Are we really alone? Is this all there is? Empty lifeless universe that wants to kill you?

Its not a paradox. The universe can be brimming with life and they would have no reason to be interested in earth

Problem with Fermi's Paradox is that you're assuming that the growth of any given alien civilization is limitless. When, simply to get into space, they'd have to create a balance between growth and available resources on their own planet first.

A species set on infinite growth likely wouldn't become space fairing to begin with. They'd, most likely, run out resources and go extinct first.

A species that has deliberately limited and/or capped its growth is much more apt to be successful. Such a species wouldn't need more than a handful of planets or systems to be prepared for any cosmological disaster that might threaten it, save those few that'd require it to leave the galaxy to avoid. Similarly, such a species isn't going to be creating super structures to generate infinite power.

Thus, odds are, any highly advanced civilizations out there are likely going to be small in scale and difficult to detect. Colonizing an entire galaxy would only ever be the goal of a doomed civilization incapable of ever doing so.

>Because why would they?

All the wrong reasons

How would they?

As in, how would they know we exist?

Assume, a technologically advanced alien race lives withing 200ly of Earth (highly unlikely).

Well, if they were scanning 100% of their sky, they would just be hearing our first (very weak) radio signals. Is it possible to tell that these now redshifted signals aren't random noise? Probably, but it's not like they have Radio Aerials, or would understand human speech in the first place. And if they're just recieving the signals now? It takes at least 200 years for them to respond. If this species is scanning even 90% of the sky, it is entirely possible they missed us, the sky is very large.

Anything outside 200ly radius? Doesn't have the possibility of hearing from us yet. Wouldn't know we exist.

Why do you think it was shit?

Thanks, good luck to you to. Blue origin is gonna need a shit ton of engineers and technicians very soon in Florida so If you're still looking for a job you could check out down here. And hey once the game is changed price wise with reusable rockets, perhaps space will open up a little for more than just the best of the best to us lowly technicians. If those spots open up the just keep applying, you never know.

quite a bit less than pic related
