    This question has lingered in the back of my mind for many years. How do we know there aren't 10^(some huge fucking number) planet-sized objects just floating out there in interstellar space?

    Actually something like that very question has been asked...
     
    Back when we first started to get a handle on galactic evolution, somebody noticed that the amount of visible (luminous, that is visible to telescopes, radio telescopes, etc..) matter in galaxies was not enough to account to the visible effects of gravity on galaxies. One of the first hypotheses they though of was that there must be a lot of invisible (non luminous) matter floating around - then somebody calculated that the amount of invisible (non luminous) matter required would in fact *be* visible, because it would obscure the stars.
     
    This kicked off the search for dark matter.
     
    So while there may be such bodies, the lack of observed gravitational effects, that they've never been observed to occult any stars under observation, and that none appear visible by the reflected light of out own Sun, gives an upper bound to how many there are likely to be. Further studies of the Oort cloud and the Scattered disk could refine that estimate, because if they exist they'll perturb the objects in those belts as they pass by.

    I thought it made it quite clear why I keep talking about galaxies - because they effect local conditions. Local conditions effect what kinds of stars are born and when they are born. What kinds of stars are born and when they are born (and thus how and when they die) affect subsequent populations of stars - and thus the planetary systems that form alongside those subsequent stars.
     

    take a count of the largest stars. then just the large stars. the medium sized... you are increasing in number, right?

    Are they increasing in number? Where's your evidence?
     

    you are at the front of a gaussian curve. now the numbers start falling as you get smaller and smaller. you have a curve with a rapid drop off on the smaller side. my hypothesis is simply that this is artificial because we simply can't see the dimmer and totally dark systems out there

    Before you can extrapolate the existence of the hand side of the curve, first you must demonstrate the existence of the right side you're extrapolating from.
     
    On top of that you must account for the fact that a star's size varies over time. The stars we see *now* (in type and location) are not the stars we would see if we traveled back 10 billion years, nor are they the stars we'd see if we traveled forward 10 billion years. In the same way, you can't extrapolate the relative position and population of LA and Seattle a million years ago and a million years hence from their current positions and population - you need much deeper knowledge to do that.
     
    For an example of that deeper knowledge, and why your method of taking a census of the stars visible today won't work - consider our own Sun. Our own Sun is a yellow dwarf today - but 10 billion years ago it didn't even exist, 10 billion years in the future it will be a white dwarf (have spent some time as a red giant along the way). Take a look at this chronology of the solar system to see the past and future of the sun so far as we understand stellar evolution today. (The second item in the table even refers to the local conditions I talk about above - conditions that vary with the location of the protostar in the galaxy.)

What would cause the proto-human female to make that choice while the proto-chimpanzee (and many other proto-species) made the opposite choice? (Since the genes are linked, you could phrase the question above using 'sensory whiskers' too.)
     
    Occam's often misused razor only work when there is a clear choice of alternatives *and* there is a clear and reasonable 'simplest explanation' to choose over the others. This isn't the case here.
     
    If I had to guess, I find it more likely the change came via sensory whiskers. Once we hunting and eating with our face, and started doing so with our hands, it seems to me that sensory whiskers start to become redundant to senses like sight and smell which operate at a longer range. This could also help explain why some species (the cats for example) have prominent sensory whiskers and why they've become vestigial in the apes.

    you've brought nothing but a bunch of legalistic and off topic issues, you haven't refuted or even touched what i am saying

    No, I went right to heart of the issues you raised - and refuted them based on scientific evidence. What you've done is simply repeated what you said before without addressing the scientific facts.
     

    the simple truth is, whenever a star/ planetary system forms, you are talking about a certain amount of mass in the region that serves as a starting point. after some time, you have a central gravitational focus, with various objects in orbit. whether or not one or two or more of those objects ignite, is simply a function of mass. and therefore, it is entirely reasonable and plausible to hypothesize that there exists a whole class of systems out there that, simply because nothing ignited, we aren't aware of them.

    Since I never said such objects don't exist, I fail to see your point.
     

    then it is equally valid to say that there may be vastly more of such brown and dark systems than systems we can see, simply as a function of random chance

    No, it is not valid to make such a statement - because the distribution of proto-stellar mass and the distribution of events and forces that influence stellar formation are neither random nor Gaussian. That's why I brought in galaxies, to illustrate that point - even though they are on a different scale, that does not mean they lack influence. Continental drift operates on a hell of a different scale than I do - but both the longer term effects (raising where I live, the Pacific Northwest, above the ocean) and the shorter term effects (volcanoes and earthquakes) have a great deal of influence on me.
     
    So it goes with galaxies - by effecting the distribution of proto-stellar and stellar matter (both on the large scale by clumping it into galaxies and on a smaller scale considering the difference between the rim and the core) they effect the evolution of stellar systems within them. The effects of that (different types of stars forming at different places in different time resulting in nova and supernova ejecting mass from stars into space in varying places at varying times) are analogous to volcanoes and earthquakes and also effect stellar and planetary system evolution.
     
    There's a time dimension as well. The distribution of types of matter varies with the age of the universe and the age of the galaxies. In the beginning, there was nothing but hydrogen. Over time, stars fused that hydrogen into heavier elements (stopping at iron) and energetic events (nova and supernova) created heavier elements and distributed them into space. The presence and concentration of these elements determine not only stellar evolution *but also* planetary system evolution. Since the distribution of those elements is non Gaussian, the types of stars and planetary systems formed from those elements cannot be either.
     
    In short, the evidence available indicates there is no reason to assume the distribution of stellar types is both non-random and non-Gaussian - every bit of available evidence points to the contrary conclusion.

    i mean, star creation should assume a gaussian distribution in terms of star size, right?

    No, we shouldn't assume star creation has a Gaussian distribution - the universe is neither symmetrical nor uniform. Not even at smaller scales - look at the different types/forms of galaxies for example. The gravitational effects and thus the distribution of proto-stellar matter in a spiral galaxy is going to be different than than the effects and distribution in a barred spiral galaxy. (Let alone the multiple other types.) Even within a single galaxy conditions are going to vary. Considering just an ordinary spiral, you'll find different conditions within the core, the arms, the edges of the arms, and out on the rim.
     
    Furthermore, the conditions vary over time as stars of varying ages go nova/supernova. Then you have to consider that not only is the galaxy itself moving and rotating, the stars within the galaxy are moving...
     
    I rather suspect that the distribution of stellar types, rather than being even roughly Gaussian, is going to be determined by the Butterfly Effect.
     

    well look at the wide base of that gaussian curve, below the minimum size needed for ignition

    If it didn't ignite, it's not a star - then technically it doesn't even belong on the chart of star sizes.

    Yes, I did read that. And that they're retiring is pretty much irrelevant - none of them have designed a new spacecraft since the early 70's (at best, assuming they were involved with Shuttle). None of them have run a lunar mission since the early 70's either. None of them have sat at a drafting board or on a console in roughly the same time - they've virtually all been promoted into management. (The Apollo era managers being long gone.)
