Invisibility is a stage in life evolution. As predation dominates the universe, life evolves to become invisible from other predators. So we humans are in a stage of evolution that we can be seen, and I consider extremely stupid flashing our position to most advanced forms of life that will anihilate us in a heartbeat. So our only hope is to find life that is barely advanced, just like algae in a watery planet, or find life that's more advanced than us and say goodbye to our existence. Just like aborigins from America flashing lights to european explorers. We would be extremely lucky to find life in the 100,000 year span that takes species to gain conciousness and develop invisibility. Not that we can't just that's extremely improbable, and dangeorous for there are also more advanced predators watching. That's why we can't find them, they're invisible. That's my hypothesis.

This thought process, i believe, suffers from viewing humanity too highly. What is the motive for an enormously advanced species annihilating humans/earth/our solar system? On the cosmic scale we are less than pests. Incapable of doing anything short of a slight radio "buzzing" to our most immediate galactic neighbors. This does no stand to change at any point in the immediate future.

  How can they trust that we won't try and wipe them out once we achieve a certain level of civilization? Sounds like self preservation to me.

  >What is the motive for an enormously advanced species annihilating humans/earth/our solar system? Here are some assumptions: * Information limitations imposed by the speed of light mean that there is very little reaction time between the development and firing of a near speed of light weapon and any defensive measures taken. This favors pre-emptive strikes even against a far less advanced civilization. Consider two civilizations 100lys away. In 80 years the less advanced civlization could develop and launch such a weapon. Maybe they already built it and fired it at you 20yrs ago. All your information is both incomplete and 100 years out of date. Striking as early as possible is the only way to be sure that you preempt such an attack. * Technological process may be an S-curve which allows less advanced species to quickly catch up and reach destructive parity with more advanced species. We can't know until we find out and by then it is too late. Caution is called for in these circumstances. We should listen and lurk until we have enough data to make reasonable risk assessments.

    This still doesn't explain why a civilization with interstellar travel technology would ever want to attack another civilization in the first place. What is to be gained? If you want resources, that's not a problem if you have the ability to travel between star systems. If you're limited by resources, you're not going to be traveling between (or building weapons that can span) star systems. Once you have interstellar flight, you have the ability to easily harvest everything in your star system, and to travel to neighboring systems to harvest whatever you want (or just synthesize what you want, as the energy requirements for transporting raw materials between star systems would be prohibitive compared to that).

These sorts of arguments are not about access to resources, they are about removing as many existential threats as possible. Fewer civilizations --> fewer risks of nutjob firing a light speed weapon which makes the star which you live around go nova. Stross writes about a Nicoll-Dyson Beam: >A Nicoll-Dyson beam is what you get when the entire emitted energy of a star is used to pump a myriad of high powered lasers, all pointing in the same direction. You could use it to boost a light sail with a large payload up to a very significant fraction of light-speed in a short time ... and you could use it to vapourize an Earth-mass planet in under an hour, at a range of hundreds of light years. [0] A civilization which can build a Nicoll-Dyson Beam should be fairly concerned that others may also have this capability.

"predation dominates the universe" -- if they're so advanced, with access to swathes of the universe, why would they bother hunting us? "Just like aborigins from America flashing lights to european explorers." How can a species so advanced be compared to people on sailing ships?

You share that hypothesis with a popular award-winning SF trilogy. My critique of that trilogy is that it doesn't incorporate the concept of present discounted value, which seems to derive from the apparently-universal laws of thermodynamics. If you have the power to destroy nascent interstellar civilizations, and the threat posed by those is their potential to use scarce resources in future, why spend the resources to destroy them now? How do you know they'll live long enough to use those resources? How do you know you'll live long enough to care? All the predators we've observed, eat their prey to sate a present (or in the case of hibernators, near-future) hunger. We've recently learned how common planets and suns like ours are. Why would any hungry alien civilization drive past all those resources to get to us? We haven't developed anything particularly tasty yet...
- Entangled 10y ago
  Life is tasty and scarce, the rest is lifeless and abundant, and according to universal laws of supply and demand, that which is scarce (life) is more expensive and in higher demand, for whatever reasons unknown to us, yet.
  - jessaustin 10y ago
    Saying that we're special doesn't make it true. There's no conceivable reason why anything we have now or will have in the foreseeable future would be worth traveling multiple light years to anyone. Perhaps if an attacker could remotely hypnotize us into spending our own resources to send it other resources, that might make us viable prey?

I highly recommend the Three Body Problem trilogy. The second book "Dark Forest" exactly deals with why the universe seems so barren as far as intelligent life goes. The theory is that all intelligent species make the following assumptions: 1. All other intelligent species have the potential to be hostile. Since there are large number of races in the universe, it's guaranteed that there are hostile intelligent species. 2. One is highly unlikely to be or remain the most technologically advanced race in the universe. Even a currently inferior race can suddenly become an existential threat after technology explosion. 3. All intelligent races prioritize their own survival and have reached the first 2 conclusions. So combining all 3 of those assumptions, one can see the logical step is to assume the universe is a terrifying dark forest filled with dangerous animals. For any resident in such forest it's natural to conceal its own presence, and if anybody reveals their location, they will be immediately eliminated by a more technologically advanced race to insure they will not become a threat. This is true doesn't matter how technologically advanced a race is because there will always be a bigger fish out there somewhere that is trying to do the same thing. In fact, I can't think of any reasons why we shouldn't take this approach. I'd love to find the existence of extraterrestrial civilizations, but I think we are being extremely foolish broadcasting our location to the universe.

  I'm more a fan of The Great Filter hypothesis. We're not finding life for the simple reason that in a thousand years, no one will find us; we'll be banging the rocks together again. It might just be that the stage between where we are now, and where we imagine going, is unlikely to be crossed.
  - knz 10y ago
    Are the two theories mutually exclusive? A dark forest doesn't imply that we aren't capable of destroying ourselves.
    - M_Grey 10y ago
      A dark forest implies that lots of species advance without destroying themselves. One interpretation of the Great Filter basically states that self-destruction to be an inevitable feature of sufficiently advanced life. So yes... for the forest to be populated requires the filter to be altered or discarded.

All settlements and encampments made use of fire so it is not unlikely that they just found each other in that way through smoke. Then, the native American population was prepared to handle Europeans militarily, but not from an immunological standpoint. Many conquests were achieved by amplification through local tribes (e.g: fall of Tenochtitlan, largest native settlement was achieved through a force composed of only 4% Europeans, the rest were Tlaxcalans). Incans were contacted during a civil war. The fiercest resistance was offered by the Mapuche tribe in southern Chile (Arauco War, which ended in 1810). Then, life hasn't evolved to become invisible to predators, it has just evolved to survive. e.g: grass hasn't evolved to become invisible to goats. Then, a predator cannot survive if all the preys die. If they're too efficient at killing or too large in numbers they eventually exhaust their food source, just like the cuckoo birds cannot do their trick in every nest and some parasites are better off by not killing their host.

If a civilization wanted to spread its reach, interstellar travel and conquer is the worst possible way. We're highly optimized for life on earth, and can assume alien life would be the same for their home planet. Evolution from simple life I think would be the easiest way to colonize. It would take a while but the life that develops would be optimal for that planet's conditions without any terra-forming
- Arizhel 10y ago
  With advanced enough technology, I would think terraforming would be far faster and easier than waiting for evolution. And if you've achieved interstellar flight, than I don't think it's a bad assumption to assume you now have the tech for terraforming.

The most famous "tool" used in this field is the drake equation. If you cut the product to the fraction of those planets, fl, that actually can develop life, you have a much higher probability than the one you get with the full equation, or by accounting {fi} or {fi,fc} too. So from a strictly statistical p.o.w. that's something more likely to happen. What has to be considered in the evaluation of the possible threat is that the way our brain is used to think, the interspecific competition model, the r/k strategy are all based on two assumption: limited resources and competition. Supposing travelling in space is something difficult/time-consuming and supposing each planet may tend towards the emergence of a dominant species, those two constraints would be relaxed: hence the coexistence of not directly interacting species may be circumstantially possibile.
