Clearly there's a xenophobic alien group consciousness that wipes out any species it detects in case it is or could be a threat to them. And here we are, beaming out a bunch of garbage and the unique signature radiation of a thousand or so nuclear detonations, squalling like a baby in a dark forest. They've built a Dyson swarm around the galactic core which is why we can't see it, while we can see the Great Annihilator ~340 light years from the core.

As to whether there is ANY intelligent life in the universe is yet to be proven. As a species we act like a virus with no intelligence at all and a high chance of killing the host before we are able to spread the disease.
I'd also make an assumption that "pure" intelligence, not influenced by animal instincts has no reason to continue it's existence, no driving force. So my anwser to fermi paradox is this: if the intelligence does not destroy itself because being stupid, then it does so on purpose.

You keep using that word that you don't seem to understand. Natural selection means that the fittest specimen will survive, not that a species wants to populate everywhere.

Also, in many nations of the world we can see a population decline even without population control politics, so your "natural selection" argument doesn't seem to hold a lot of water.

Fitness means how you contribute to the gene pool therefore having more successful reproductions = more fitness. Maximizing fitness means populating everywhere.
>In many nations you can see population decline
Short term because other sub populations within that nation (or out of it) take their place. An average population decline still equals a net gain over a long period of time as long as one population within that group has a net + reproduction rate.

You larping as a biologist doesnt make you one, neither does using words like "subpopulation" that sound smart but arent actually used by biologists.

You have 1 son, some other person is having 5 sons, because of that he is more fit and within 100 years his children will out number yours. This is why /pol/ is so scared of brown people because they reproduce faster meaning that they in 100 years more brown people will exist compared to the number of non brown people. It's also why ideologies that promote reproduction will spread faster than ones that do not for example Islam being the fastest growing religion despite being the most retarded.

I think we aren't alone but it's just that space travel is too hard and can't be solved, even with far more advanced technology.
The recent improvement's in technology (since the beginning of the industrialization) made us think that nothing is impossible and that we can and will always continue improving technology until we basically rule the universe.
The reality is that, at some point, progress will slow down and probably even stall for a very very long time.

Subpopulation is a real word that was used correctly brainlet.
>Population decline can be seen in almost every nation
False, outside of very specific places like Japan nearly every nation has a net + population growth rate. The growth rate fluctuating in no way disproves what I said because it is still positive and even if it was negative that would only be until a population within (a subpopulation stupid) became the majority.

It's still positive anon.

There is a reason scientists think the human population will reach 10 billion by 2050 rather than become smaller.

We really, absolutely do not have any clue whatsoever at this point though. The chances of life developing independently on a given hospitable planet in the timeframe provided by the existence of the currently observable universe and developing intelligence could be something like 1/5.

Or they could be something like 10.0^-10000000000000000 for all we know, and it's just that we happen to live in one of an infinite number of universes in which this miraculous thing happened.

"Intelligence" as we see it is overrated. Ants for example are really sophisticated and even civilized beings and yet they are hardly anything more than biological robots.

>> No.9885331

The colonisation argument is stupid. It is absoluetely impossible for a central government to exist beyond several solar systems.

I mean, let's imagine earth has a colony in Alpha Centauri, so just 4 light years away. Let's also imagine that space travel has no sci-fi-magic component to it and travelling there takes at least 100 years. So now let's imagine a crime happens in Alpha Centauri. Just reporting that back to Earth would take 4 years. E.g. you call the government, and it takes 4 years for them just to get the message. Then you send your troops, and it takes at least a century for them to arrive at the crime scene. This is obviously not going to work. So "galactic empires" will not exist, not even empires that span a few stars will exist.

Instead, if we had an Alpha Centauri colony, it would be completely independent from us. So let's imagine 500 years later, they have build themselves a very sophisticated civilization there that holds a few million humans. Now the question is, will we further colonize, or are we instead going to trade or war with the former colony? And will the former colony want to send colonies themselves, who will immediately become independet, or will they prefer to trade/war with us? As a matter of fact, it seems a bit unrewarding to send more colonies, that will immediately become independent factually, after having enough to absoluetely guarantee the survival of your species (so less than 10). At this point, why would you further colonize? You have not much to gain anymore and could theoretically create your own enemy that will come one day to destroy you.
