  • TLDR: Hard disagree on almost anything you just said

    Well historically it is not a terrible system, it is very stable and tends to not self implode regularly like democracy does.

    Yeah if you ignore for example wars of succession, because of incestuous family ties, arbitrary rule, repression and exploitation of its citizens, one could call it stable… Although the escalation and tyranny unfortunately are baked into the system.

    if you look at monarchies historically they tried very very hard to avoid having rebellions in their hands and usually worked in the interest of the nation, as the interest of the nation was the interest of the monarch.

    Have you ever read history books? Sure some rulers may have had that kind of view but theres also plenty of megalomaniacal, terribly violent and unjust rulers in those big ol books of history. And since it is an imposed rule of tyranny there’s really only violence to get rid of an unjust ruler, you know a neat thing about democracy? Violence is the last resort to getting rid of rulers because we can vote! Crazy right?

    So if a democratic nation seems headed towards anti democratic rule, it would seem to me that a better goal would be to install a monarchy instead of a fascist.

    In that case- what’s the fucking difference? Oh, to avoid an autocracy let’s install an autocracy with cherry flavor… Great?










  • That’s not entirely true, cancelling sound waves can also be done on a large scale. I’ve seen it on festivals or other open air venues, where they stack two rows of subwoofers behind each other in a precisely calculated distance to cancel out the bass notes towards the back of the stage, meaning walking in front of the subs you could hear it normally, walking behind them and the bass notes where very faint and clearly coming as a bounce back from walls or the like. So they effectively cancelled out the frequencies towards the back.

    But that doesn’t help OP since that works way better on lower frequencies, with higher notes you’ll need the precise localization you’re talking about. So the high pitched noises from a hard drive probably won’t work.

    Orbital mechanics can be a bit counter intuitive.

    To raise an orbit you need to speed up, but your overall orbital speed will decrease, since the distance grows the higher the orbit gets. So you’ll need to speed up to reach escape velocity to escape Earth’s gravitational pull, once you managed that, you enter the orbit around the sun. To lower an orbit you’ll need to lower your speed, while your orbital velocity will increase, since the orbit gets smaller.

    The “fuel” of a space craft is measured in Delta v, which describes the ability to change the velocity of the vehicle, the unit is m/s or km/s To reach a low earth orbit you need around 10.000 m/s Delta v, if I’m not mistaking another 9.000 m/s to escape velocity, then you’re in a sun orbit, I don’t know how much you need from there, but id say at least another 15-20km/s

    You can look up escape velocity which is the velocity required to exit a gravitational body completely.

    That’s also what makes getting to the sun so difficult. At first you got to speed up to escape velocity to escape the Earth’s gravitational pull, then you enter an orbit AROUND the sun, where you will have to slow down by a lot to lower your orbit enough to get into the sun. Miscalculate and you’ll fling yourself out of the solar system.
