What Do Alien Civilizations Look Like? The Kardashev Scale

The observable universe is a big place that has been around for more than 13 billion years. Up to two trillion galaxies made up of something like 20,000 billion billion stars surround our home galaxy. In the milky way alone scientists assume there are some 40 billion earth like planets in the habitable zone of their stars. When we look at these numbers it is hard to imagine that there is nobody else out there.

      Your argument about the nonexistence of a type 3 or above civilization is flawed why should we be able to detect their technology if we cannot imagine what it might look like (yo said it yourself). While you also offered a similar perspective at the end It still was bound to the assumption that a civilisation would develop inwards. If they would be able to utilise dark energy we would not be able to detect it since we can't even detect dark energy or really understand what it is for us its an extra term (not necessarily a constant actually the evidence points not toward a cosmological constant but rather a function) in the Einstein equations we don't know where it comes from we only know it influences the large scale structure of spacetime.

    Thought experiments like this make me laugh about how disconnected astronomers, physicists, and cosmologists are from biologists. From a very biologically practical point of view, there are seemingly insurmountable challenges to endeavors like interstellar space travel. Space adventurists always treat the biological part as a problem that more science will obviously be able to fix in time, when in fact shooting a rocket into space is easy compared to, for example, deep-freezing a human body for 5000 years and reawakening it at another star system. Deconstructing a body and "beaming" it like in Star Trek is even more a non-starter: the information required to make such a reconstruction possible would bog down dozens of supercomputers running in parallel. Another option is teleportation by bringing two areas of spacetime together to allow passage across vast distances, but some things simply aren't possible, and I suspect this and lightspeed travel are two examples. Colonization can probably occur within local regions of space, where maybe multiple planets exist within the habitable zone of a single sun of where multiple habitable solar systems exist within a few light-years (at most) of each other, permitting generational ships to have a realistic chance of successful voyage. Generational ships present a lot of problems in themselves: even allowing for deep-freezing technology, which would be extremely difficult to refine, you'd have to have a skeleton crew alive on board. For a species that is active enough to have developed high technology, there are two possibilities: they're endothermic/hot-blooded, like humans, permitting biological activities to happen at a rapid pace at the cost of enormous food requirements, or they're ectothermic/cold-blooded but come from a relatively warm world. The second type of creature would be more likely to survive deep freeze and wouldn't require as much food, but the skeleton crew would require external heating. In either case, the generational ship would require an enormous reserve of energy, either in the form of food or potential food energy or in chemical or nuclear energy to heat the ship to allow biological functions to continue. When you look out over a time horizon of 100+ years in such a ship, including resources to resuscitate and sustain the payload passengers on a foreign world for long enough to create their own food at the destination, the total size of such a life package becomes prohibitive as anything but a "last-chance-for-survival" Hail Mary mission. Realistically, galaxy-wide civilizations won't exist in any meaningful way. Even if a species had developed a reliable way to propagate itself across numerous star systems, can it be said to be a "civilization" if the constituent societies, can barely coordinate with each other due to the enormous time gaps in data transmissions?

    The add before this video told me there was a tribe of natives that had never seen advanced society of any kind until WW1 or WW2 times. They thought of the westerners as God's and when the westerners left the island, the natives built wooden planes and runways to pay tribute that the gods would some day return. This is the exact thing makes me think about the pyramids, whether in Egypt or South America.

    [9:03] "Their influence would in all likelyhood be so all-encompassing and their technology so far above our own *that we couldn't miss them.* The galaxy should flash with their activity..." The conclusion you make does not seem right. How could we tell the difference between "natural stuff" and "level 3+ civilization artifacts"? Given that it becomes nearly impossible to imagine what a level 3 civilization would even look like, there could definitely be several high-level civilizations toying with our galaxy right now and the black hole at its center is actually their doing for all we know. For example, dark energy could be the scar of a struggle for control over our universe by multiple level 5+ civilizations...

Sounds like gods everywhere not just earth....and why does God need so many names if we are the only beings that know of it?? Also would love to know why the book of Enoch was taken out of the Bible to...he literally goes to space and sees the other planets and is given knowledge of how many days are in a year and our neighbour constellations and there names...even is taken to see the god of all in person.

    Something has been bothering me about this, and I think I figured it out. There is no reason for a species to actually achieve any of these types. We are just a type 0.75 species, and yet we are a handful of decades away from colonizing other planets. Why would a species need or want to go the full route of building a dyson sphere. If they are really that greedy and expansionist, they would skip all that and book it out of the solar system at the earliest opportunity. Infact I find it unlikely that any species will ever hit all of the milestones for any of the types.

    I think life achieved type 1 several hundred million years when it colonized land. From this perspective, the harnessing of electricity and subsequent rise of computation mark the transition to type 2: A synthetic form of life that dwells in the gravitational fields of stars and feeds off their energy, using this energy to generate simulations for humans to live in.

    Wonder what type of civilization these craft belong to that are being sighted and being made public finally after 70yrs....I'm guessing type 1-2??....a theoretical Zero Point Energy harnessing could deliver unlimited energy aswell...when it comes to power needs. And as for distance if you could manipulate the fabric of space you could distort it even fold it like folding a piece of paper from point to point...you don't need to travel in a straight line.
