    There are 7 alien spaceships orbiting earth right now the size of Jupiter, but they are invisible. They are not revealing themselves to us yet because we are not ready. But they are mind controlling the world leaders to prevent us from killing each other in a nuclear war. They helped trump win so as to save us all. There are also millions of people living underground in a whole separate society. Hilary Clinton is a lizard person, etc.

    The first ones I could think out of The top of my head:

    • Wind turbines are being powered by Diesel Generators
    • In The Middle Age people were like 4m tall, which is the reason why the entrance gates of castles are so big.

    There are probably way more, that I forgot (my parents are quite deep into conspiracy theories and so is their entire social circle).

      This guy clearly never has been to an actual castle or medieval townhouse and bumped his head on every second door…

      And the wind turbine one is so bonkers I can’t even imagine someone saying that in a non-joke-context…

      If the trailer has very good brakes set to full power even when nearly empty, it’s actually true, but I doubt that’s the case…

        In that exact case yes, but I like to operate on the assumption that my trailer brakes are permanently broken. I’ve had them fail to operate mid-trip because they’re fucking trailer brakes.

        I am pretty sure physics says “no”:

        Ff <= µ*Fn

        • Fn is proportional to the mass of the trailer, so it is irrelevant for the deceleration (a) if it is empty or not (because Ff = m*a).
        • µ is a constant relying on the tire/ground connection. Comparable to the towing car (if you happen to have car tire quality ones on your trailer, which might be doubtful)
          .

        On top of that, typical car trailers use overrun brakes that per definition work by exerting an additional force on the towing vehicle in the direction of movement that is then used to activate the trailer brake.

          Fair enough, car trailers do have garbage braking most of the time anyway. I may be biased because locomotives are so heavy and the traction you get with steel is shit so they actually benefit from some load behind…

          That is an oversimplified friction model that does not apply well to emergency braking. I still don’t think you get a better braking distance with a trailer in a typical situation but thats not the reason why.

    A roommate once told me that cows “have one hole for babies and pooping”, i.e., a cloaca, but he didn’t know that word. I told him that isn’t true, they are typical mammals so they have the full complement of parts.

    I was sitting at my computer so I pulled up a diagram which he said was wrong. Then he asked to show me and started searching for things like, “cow hole”, “cow butthole and birth canal”, and “cows with just one hole” before I regained my senses and told him to go away.

    The worst part though was the next day when my girlfriend was using my computer and saw the searches so I had to explain to her the conversation and he came back in to defend himself and tried to look up cow smut AGAIN.

    That green grapes were grapes that weren’t ripe. Couldn’t believe my ears and had to point out that green/white grapes make white wine and red grapes make red wine, there’s no such thing as red grapes that are green because they’re not ripe.

        that’s awesome! i’ve watched a bunch of videos on vineyards and it seems like such an intense lifestyle, especially harvest time.

        wait there are red grapes which are unripe and look green? or white grapes can be green before they’re ripe?

          such an intense lifestyle, especially harvest time.

          Getting up at 6 in the morning, your mum is already cooking the lunch for 15 people to be later packed into insulating casings to be taken with you to the vineyard, dad outside waiting already for you to prepare the trailers hooked up to the tractor, then after 8 hours hard manual work in the 45° angled vineyard processing the grapes with the press, tending the previously pressed juice that already started fermenting, than shoveling nearly a ton of grape remains into a large container and compacting them (for latter distilling the stuff to grappa) then falling into bed at a quarter to 11?
          Yeah, somewhat intense…
          During other times of the year (especially in winter) on the other hand life was almost meditatively chill.
          I really liked that, but it is just incredibly hard to make decent money with it, considering all the work…

          And yes, all of our grapes were green (and completely hard) during much of their ripening process, red and white ones alike. They just change colour and become soft and sweet during the last few weeks before harvest.

    That Jesus had 20kg stones he’d send Earth in the Doomsday. And that would be the day I’d regret not listening to the person saying it.

    …mostly because I asked her why should I take the Bible more seriously than the Gîta, the Quran, or the Poetic Edda.

    ~25y later I’m still waiting those 20kg stones.

    I had an economics teacher in high school who warned us that we’re better off at the higher end of a lower tax bracket than the lower end of a higher one, because a higher bracket being a higher percentage of taxation meant you’d lose so much more money that you’d be holding less in the end until you pass the threshold within that bracket where you get back ahead of the tax.

      If the tax isn’t incrementing continuously but in discrete steps, this sounds kinda plausible to me… Also I know of certain hard limits in my country that will force you to suddenly pay some additional kind of taxes or loose certain privileges once you cross them.
      This means that earning a single Euro more could lead to loosing hundreds or thousands in effect…

        if it were to make you lose certain benefits that is another story. but just based on tax itself, the higher tax brackets are only applied to the money that you earn beyond the threshold amount. for example, if you have 2 brackets, 10% up to 40k and 20% beyond that, and you earn 60k, you would end up paying 4k tax on the initial 40k and then another 4k on the 20k beyond that. there’s no scenario in which you would end up earning less due to getting into a higher bracket

          Ok, seems your tax system is different than ours (which applies a earnings-dependent percentage to the whole earnings, minus some free amounts which are again often depending on the sum of earnings - yeah, our tax system sucks…).
          So it actually was a stupid thing to say.

              Damn, you are actually right. Just did a deep dive into Wikipedia and it turns out that I misinterpreted the curves showing the tax percentage depending on the income completely wrong during my whole life. It doesn’t show the tax percentage to be applied to your earnings, but you have to integrate over the curve from 0 to your income…

              TIL…
