    What @Gaarst said.

    What would be perfect for KSP would be a bespoke-created physics engine for simulating vast volumes of space with high resolution.

    One did not exist, and creating one from scratch would have been prohibitively difficult (for starters you could add 2 or 3 years to KSP development time, double the cost to cover the salaries of the people they would have needed to hire to create it, and then add a bunch more cost on top of that because there would be few customers wishing to license the use of their engine.)

    Porting from one non-ideal engine to another non-ideal engine would be a lot of work for nothing.

    Squad did not make the mistake of "choosing the wrong engine", they made the "mistake" of building a game/sim that went beyond all contemporary expectations of what you could do in a game/sim world.

    One should not say "Squad should port KSP to a differnt engine" or "If only Squad didn't choose unity..."

    One should say "Gosh it never fails to impress me how much Squad achieved in KSP with the limitations of the physics engines available to them."

    Seriously, read about floating point errors and how KSP handles them, its quite clever.

     

  2. i thing that KSP hast grown to Big..
    To fast to Big...

    Look; SQUAD is a marketing company.

    and KSP has grown from a "i do something usefull/funny" thing to a realy, heavyweight game and simulation...

    It has grown realy big.

    a big Programming Project, maybe to big for a smal marketing company. - they havnt enough recources (know how, manpower) for that.

    Yes they can increase the recources for that.
    but what happened then?

    I think KSP - to big for SQUAD, to small to sell

    While there won't be a need for any aerodynamics, won't the g forces experienced eventually come into play? Can you accelerate the ISS very hard without something snapping somewhere? And tidal forces will limit you depending on size, I believe the ISS has to take them into account to avoid tumbling. I guess a space only transport would be using low thrust engines for most things though.

    yes, g forces..

    and from this point, -> the whole thing has struts/caples to avoid wobling...

    Electrical engines (like vashmir, Hal and (maybe) the EM drive )could save a lot of working mass  ... - but they have low thrust..

    so thats fine from 2 points -> low working mass and low forces...


    and because inflatable:

    You can inflate it first, and thenn add layers to that..

    like a foam -spray...


     

  4. 32 64 bit dosnt make any differenze.

    the big question is: why dos it work as root...

  6. Hi;

    My problem was, the game only start as root.

    i had removed the game  complet, even the savegames.

    removed the game with the steam (deinstall routine)
    removed the game folder with the console...

    i think there was nothing left on the pc..
    and installed it new.

    but steam cant start KSP, it runs only as root...

    :/

    anything i forgot?

    in the game folder, with ls -lisa all rights are for the current user.
    there arnt any data/directorys for "root"...

     

  7. The Solar-array are a good idea.
    But what about the industry that needs a huge amount of Energy.
    ore more worse, coal as reagent, like the steel/aluminium produktion?

    To extract that from the air, you have to use a lot more energy.

    or Aircrafts.
    they need a lot of energy (a turbine from a aircraft, i think, was about 3,6MW of Power). too much to carry about by Batteries.
    you have to use fuel (syntetic, renewable or fosil) -> if you want to syntetisice that , you need a huge amount of power.

    A fusion reactor are good.
    One fusion reactor produce a lot of energy, at a single point -> you can add there a lot of massive power-consuming industry.

    So you dont have to transport the energy over a huge distance.
    Solar-power are good enough for the private-buildings like houses, and so on.

    Ant Man had a really horrendous one. They explicitly state the technology relies on shrinking the distance between atoms. So, there should be a limit to how small you can get. Yet at one point they talk about going "subatomic", which should be impossible by the movie's rules. Not to mention the whole "mass is conserved" thing which was supposed to be one of the reasons Ant Man can do some serious damage when shrunk gets haphazardly applied. Internal consistency, that's all I ask

    And another thing that has some spoilers:

      Hide contents

    At the end of the movie he goes "subatomic", and we see the worst depiction of basically everything at the micro, nano, and femto scales.

     

    yes, ant-man bugs me a lot.

    If he save his whole mass, the whole mass (let me say 50 kg) are aplied to a areal of 0,2*0,2cm...
    thats 0,04 cm²
    with 50 kg thats 1250kg/cm²

     

  9. maybe there are parts like balloons.

    then cilindrical parts -> more easy to build.

    and every part has docking ports, and slots for struts/cables (to prevent this thing from wobling) - so this whole thing can be modular

    (btw: i miss that i can strut docket  things in orbit, -> to prevent space-stations from wobling)

    a lot of solar arays (better weight/energy ratio than a heavy fision reaktor)

    A lot of smaler ships are docking on this thing  - > like the skylon to land/lift things to orbit

    Big electrical based engines -> safe a lot of working mass.


    Welding: you can clean the parts, and then you can heat the tings if you let flown a lot of ampere between the parts.

    thats a good thing about the vakuum in space, you dont need an inert-gas ore something else.

    You don't need anything - just clean them off.
