Why dont we see any other life or evidence of it? Why no galactic empires sending signals around?

Is something going to wipe us out or are we the first ever advanced race to make it this far?

Are we going to colonize the galaxy or are we doomed?

I think the assumption it makes that life-forms would naturally want to leave a planet is really fucking stupid. It's the same argument people make about evolution; "why aren't we super tall and strong and everyone is a genius", because natural selection isn't a ladder. These aliens could be completely happy on their planet sitting around eating and fucking (or whatever alien equivalent) for billions of years if the environment is feasible, it's about whatever works not leaving the planet. That is not what every organism is destined to do. Honestly, it's probably not what we as a species are destined to do.

Why the fuck would you build Dyson spheres/swarms instead of highly advanced and compact fusion systems? If you can engineer and build colossal systems like Dyson envisioned one would imagine you could figure out fusion and perfect it. I think the Dyson sphere idea will end up being remembered as an extreme expression of mans parasitic materialism on a grandiose scale.

Because you have all this energy being radiated into space that you're not gonna be able to use if you don't build a Dyson Swarm. Plus, it's not too dificult to turn a Dyson Swarm into a Shkadov thruster, so you can crash stars into eachother in order to harvest the energy from supernovae and farm black holes.

>But once self-propagating systems have attained global scale, two crucial differences emerge. The first difference is in the number of individuals from among which the "fittest" are selected. Self-prop systems sufficiently big and powerful to be plausible contenders for global dominance will probably number in the dozens, or possibly in the hundreds; they certainly will not number in the millions. With so few individuals from among which to select the "fittest," it seems safe to say that the process of natural selection will be inefficient in promoting the fitness for survival of the dominant global self-prop systems. It should also be noted that among biological organisms, species that consist of a relatively small number of large individuals are more vulnerable to extinction than species that consist of a large number of small individuals. Though the analogy between biological organisms and self-propagating systems of human beings is far from perfect, still the prospect for viability of a world-system based on the dominance of a few global self-prop systems does not look encouraging.

>>11573465
>The second difference is that in the absence of rapid, worldwide transportation and communication, the breakdown or the destructive action of a small-scale self-prop system has only local repercussions. Outside the limited zone where such a self-prop system has been active there will be other self-prop systems among which the process of evolution through natural selection will continue. But where rapid, worldwide transportation and communication have led to the emergence of global self-prop systems, the breakdown or the destructive action of any one such system can shake the whole world-system. Consequently, in the process of trial and error that is evolution through natural selection, it is highly probable that after only a relatively small number of "trials" resulting in "errors," the world-system will break down or will be so severely disrupted that none of the world's larger or more complex self-prop systems will be able to survive. Thus, for such self-prop systems, the trial-and-error process comes to an end; evolution through natural selection cannot continue long enough to create global self-prop systems possessing the subtle and sophisticated mechanisms that prevent destructive internal competition within complex biological organisms.

>Meanwhile, fierce competition among global self-prop systems will have led to such drastic and rapid alterations in the Earth's climate, the composition of its atmosphere, the chemistry of its oceans, and so forth, that the effect on the biosphere will be devastating. In Part IV of the present chapter we will carry this line of inquiry further: We will argue that if the development of the technological world-system is allowed to proceed to its logical conclusion, then in all probability the Earth will be left a dead planet-a planet on which nothing will remain alive except, maybe, some of the simplest organisms-certain bacteria, algae, etc.-that are capable of surviving under extreme conditions.

>The theory we've outlined here provides a plausible explanation for the so-called Fermi Paradox. It is believed that there should be numerous planets on which technologically advanced civilizations have evolved, and which are not so remote from us that we could not by this time have detected their radio transmissions. The Fermi Paradox consists in the fact that our astronomers have never yet been able to detect any radio signals that seem to have originated from an intelligent extraterrestrial source.
>According to Ray Kurzweil, one common explanation of the Fermi Paradox is "that a civilization may obliterate itself once it reaches radio capability." Kurzweil continues: "This explanation might be acceptable if we were talking about only a few such civilizations, but [if such civilizations have been numerous], it is not credible to believe that every one of them destroyed itself" Kurzweil would be right if the self-destruction of a civilization were merely a matter of chance. But there is nothing implausible about the foregoing explanation of the Fermi Paradox if there is a process common to all technologically advanced civilizations that consistently leads them to self-destruction. Here we've been arguing that there is such a process.

That’s just some mad scientist shit right there. Why build massive solar arrays like that when you can just harness fusion directly in compact reactors, it would be a much less colossal and expensive endeavor, and would be possible far sooner than any Dyson system.

there are an estimated 200–400 billion stars in the Milky Way (2–4 × 1011) and 70 sextillion (7×1022) in the observable universe. Even if intelligent life occurs on only a minuscule percentage of planets around these stars, there might still be a great number of extant civilizations, and if the percentage were high enough it would produce a significant number of extant civilizations in the Milky Way. This assumes the mediocrity principle, by which the Earth is a typical planet.

I would say most, in the entire universe. The chances there is an alien race advanced enough to own an interstellar empire in our own galaxy is super fucking small in and of itself. Because we have already received every wavelength humanly possible within this and several others.

If there is an interstellar race out there, it's definetly not in our galaxy and probably not in the next 100,000 galaxies next to us.
