    I was thinking about how to classify civilizations and came across the Kardashev Scale.

    After reading the requirements to achieve the different type civilizations. I have serious doubts about humans even achieving a type I civilization, let a lone anything higher than that.

    But I am willing to listen to what others think on this subject.

    Interesting, I had never heard of this before. Not sure though how realistic or useful this scale actually is, in practice, since there could be many other ways to measure how "advanced" a civilisation is. For example, a species could be highly advanced without ever having left their planet - they might simply have chosen not to engage in space travel, for whatever reason. Does that make them primitive ?

    I think this classification is a little simplistic.

    I think that scale is meant more for detection than meaningful understanding. Like, at such a level they'd eclipse their star, at another level they'd appear as nebula, etc.

    I dont find this scale all that interesting or useful (pointless).

    Maybe, but the idea of it is interesting. I'd be perfectly happy living in a type I civilization. But I'm not happy thinking that may be to much to ask of humans.

    It claims a type II civilisation could harnes the energy of an entire star via a Dyson Sphere but would a given planet even need that much energy? The output of a whole star? How much can you overpopulate a planet before being easily capable of moving out to a new one?

    I think it's a bit far-fetched.

    I embrace Dostoevky's opinion on the matter...

    The Dyson sphere replaces the planet--probably built with the materials off every solid matter in that solar system, plus new solids created by their understanding and control of fusion.

    Once you get all the worker robots built for the job, you just let them start working. It could start producing energy shortly after some of it has been completed and expand from there over time. That being the case who cares if it takes more than a couple of centuries to build it?

    I don't think we have any right to think of ourselves as "civilised" until Planet Dirt is no longer in a state of constant planetary civil war.

    Ok. I was just wondering how a single planet could ever need that much but if the whole solar system is colonised then it would be a different story altogether.

    As for logistics, it's not hard to imagine that it could be done given the right technology.

    Here's an interesting text from Wikipedia:

    Dyson sphere - Wikipedia, the free encyclopedia

    SETI has adopted these assumptions in their search, looking for such "infrared heavy" spectra from solar analogs. As of 2005 Fermilab has an ongoing survey for such spectra by analyzing data from the Infrared Astronomical Satellite (IRAS).[25][26] Identifying one of the many infra-red sources as a Dyson Sphere would require improved techniques for discriminating between a Dyson Sphere and natural sources.[27] Fermilab discovered 17 potential "ambiguous" candidates of which four have been named "amusing but still questionable".[28] Other searches also resulted in several candidates, which are however unconfirmed.[29]



    References [28] and [29] look interesting but I'll go and have breakfast first.
