So as we discover that the goods for life are literally everywhere what's the rub? Intelligence is the big jump? Life is everywhere but hiding for some reason?

Could be it's just really hard to pick up life-transmitted signals from all the stellar noise. Obviously one would try to pick a quiet frequency, but transmission across light year distances would still need an awful lot of energy. Or maybe there's a space internet but we're just not aware of it yet.

I think we take it for granted that if your planet simply doesn’t have the right resources available, you’ll never truly have an Industrial Revolution. If there is life, it’s more probable it is stuck in some crude Stone Age state rather than high tech.

  Both the stone age and industrial resolution took over 4B years to produce from the ingredients.
  - wolverine876 3y ago
    For the industrial revolution: after 4B - really ~4.4999995 BY out of ~4.5 BY - arguably it only happened once in a very limited geographical area, and everyone else learned it from them.

  I struggle to think of a planet that wouldn't have the necessary ingredients for an industrial revolution. I don't think you need fossil fuels at all; on Earth, even without fossil fuels, we probably could have eventually gone from biofuels to wind/hydro power to solar/nuclear (these requiring a lot of energy for the refinement/processing of raw resources). It would have been a slow and gradual process, but if this process took about ~150 years with fossil fuels, I bet it would have only taken something like 500 years without them - a tiny blip in time, really. I think any planet capable of hosting carbon-based life would be able to at least produce wind energy, and probably most (assuming a rocky planet with liquid water and an atmosphere containing oxygen) would be able to develop all the energy types I mentioned. Solar and nuclear might be relatively less feasible if certain elements aren't common on that planet, and battery storage might also suffer from lack of resources. But wind and hydro alone are probably sufficient to eventually be able to develop controlled fusion down the line and have most energy-resource issues obviated. Even if you imagine some exotic form of life not like ours at all, on a planet that doesn't necessarily have water or an atmosphere, the life has to be able to derive energy from some kind of external source, whether it's by facilitating some chemical reaction like our deep sea micro-organisms or photosynthesis. Most likely that energy can be harvested in an automated fashion, and it's probably relatively abundant if life is able to evolve to the point of intelligence. For it to be completely inaccessible due to lack of resources, IMO you'd have to get into truly strange scenarios like intelligent life somehow developing in a nebula or the atmosphere of a gas giant.

    I mean, I disagree about fossil fuels. I don't believe we make the necessary advancements without incredibly energy dense fuel. Everything you listed required a base of energy dense fuels for the process in some fashion. It's very hand wavy to say. Well we would've just figured it out. I'm not convinced? So if we were the first large life to form on the planet, and there weren't any fossil fuels, I think we'd be screwed. I think we would've stalled until something burned us as fuel.

      > Everything you listed required a base of energy dense fuels for the process in some fashion What about wood, or more "advanced" biofuels (idk, some kind of highly productive grass or a refined algae product), prevents us from developing wind and hydro power? Those were both developed before fossil fuels were widely used anyway. They produced mechanical power instead of electrical, but only because electricity was not understood yet. The more energy you have, the easier it is to scale energy production up, but you have the resources required to initiate that process with just biofuels. And once you have a base of wind and hydro energy, that allows you to begin the feedback loop of using that energy to assist in constructing more power generation in a virtuous cycle. edit: I'll also add that the industrial revolution came about after there had already been notable advances in mechanization and manufacturing - the introduction of fossil fuels quite literally threw gas on the fire, but people had started developing increasingly sophisticated machinery like the cotton gin (https://en.wikipedia.org/wiki/Cotton_gin https://en.wikipedia.org/wiki/Cotton_gin) and mechanically-powered loom (https://en.wikipedia.org/wiki/Lancashire_Loom https://en.wikipedia.org/wiki/Lancashire_Loom) before fossil fuels started being widely used. And indeed, many of these were hydro-powered.

Simple life is probably fairly common. But intelligent life that's reached a technological level such that we would notice them is probably pretty rare. It could be that we're the only ones in this galaxy that are currently at this detectable level and the distances to other galaxies is just too far to be able to detect those that might in other galaxies.

  We actually have a piece of evidence for this: How long the dinosaurs were around compared to humans without developing technology.
  - aswanson 3y ago
    Yeah. We've only given off signals detectable in space for 200 years and have only existed for around 200000 years as a species. Less than a blink of an eye from a galactic time perspective.

    And how many times did a potential intelligent (human-like) species evolve in that period before being wiped out by predators?
  - DemocracyFTW2 3y ago
    > dinosaurs were around [...] without developing technology That's what they want you to think but the historical records of the USS Voyager clearly show that some branches of dinosaurs (haplosurus I believe) did eventually evolve to develop space travelling technology (which is how they survived the Chicxulub event).

Life doesn't require Intelligence.

Intelligent life may very well be everywhere (on the order of multiple civilizations per galaxy), but its impact is undetectable at such distances, just like someone dropping a pebble in the ocean off the shore of Tokyo is going to be undetectable in LA.

So as we discover that the goods for life are literally everywhere what's the rub? Intelligence is the big jump? Life is everywhere but hiding for some reason?
