    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.

      I could see where, if the trailer has good brakes and a relatively light load, it could provide additional stopping power.

      That’s usually not going to be the case though.

        I’m reasonably sure that you’ll never stop sooner, you’ll likely be exceeding the traction from the tires at that point anyway.

        The trailer wasn’t braked.

          It is my understanding that there are two types of brakes you’ll find on trailers, the ones activated by a weight that swings forward under the force of the truck’s braking, and electric ones. Neither are anti-lock or anything fance, and neither are really designed to provide actual stopping power, the drag they add is meant to help maintain control. Most of the braking force is done by the truck’s front wheels.

          I don’t think it’s impossible for there to be a spot on the performance envelope where you’ll stop a few feet shorter with a lightly loaded trailer, but I bet it’s not particularly large.

          It is impossible with a trailer with no brakes.

            Hence the “stupidest thing” :-)

            There might be a way to load a trailer with perfectly spherical chickens and brake a certain way that maximized braking performance to… get a MythBusters result.

            I assure you, that argument is exclusive to this forum, and wasn’t part of the dialog in the car at the time :-)

    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.

          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.

        A lot of it is designed to fit in college dorms. So some are on the small side…

        But this guy also didn’t understand that beds came in standard sizes, and was worried a swedish store (in the US) would be selling bedframes sized based on swedish standards and wouldn’t fit his mattress… It was a dumb conversation

          Ok, so might be different product offering in the US then. Which makes what he said even doubly stupid.
          College dorms are not as much of a thing here in Europe and Ikea stuff here is normal sized, just standardized, mostly with that minimalistic Ikea look and easy to assemble by oneself.

              You before said it was based on the stuff that is used for college dorms, so I gathered he was looking at similar offerings as in other stores but just assumed it to be smaller because of some Ikea-specific reasons instead, so he then had to make up a suitable reason.

              But on the other hand, perhaps he knew that College dorms are not a thing in Europe and had to find a reason the Ikea sold small furniture regardless of this.
              In that case his remark wouldn’t have been stupid at all but a valid speculative thought process based on deeper cultural knowledge.

        I think IKEA furniture does read as a little small to Americans because it is European designed and European furniture on average seems a little smaller than American furniture, to my eye at least.

          That sounds plausible and might be true.

          Also I have to say that I am a rather tall guy and the only height-adjustable desk that had a usable maximum height for me e.g. was the one from Ikea.
          I think it is definitely not a specific Ikea or Swedish thing or has anything to do with the people being smaller (If anything, I think to remember that typical US citizens are actually smaller on average than most of the people in the northern parts of Europe…)

              Thanks!

              Regarding the beds: First thing I noticed were the HUGE headboards. I thought we had a really big one on our bed, but it is perhaps only half as tall as most in the video.
              And while the beds themeselves did look somewhat big, they also seemed to be quite short? I am about 1.90m (~6ft 2inches) and got the impression that I’d either bump my head or have my feet hanging over. But that may be an optical illusion, perhaps because of the widefield camera, the width of the beds or again in comparison to the towering headboards.

              What I also noticed was that the presentation seems not to be grouped by function or room (so beds near sofas near dining tables…). Is this typical?

              Also I was missing a lot of actual, well, “useful” stuff. Kitchen furniture seemed not to be present at all, I saw no child furniture only some youth room stuff, but not much and not very practical and there were no bigger cabinets or other furniture to put away your stuff…
              Do you have specialized stores for that or has it just been the youtuber’s incomplete selection here?

              Overall the presentation of the products is much more spacious and giving a much more “luxurious” impression. When entering a similar exhibition here in Germany I would probably walk right back out again, because clearly not my price range… 😆

                American furniture stores don’t tend to prioritize organization, IMO. It’s more about what fits where.

                Beds do tend to be tall, and sofas and chairs are both tall and wide. Stuffed furniture tends to be overstuffed.

                Extremely tall mattresses are popular, so headboards must also be very tall or they’d be hidden.

                The standard-sized American bed is uncomfortably short for people over 6 ft tall, despite it being pretty common to be tall. Longer mattresses are available at a higher cost.

                Americans don’t tend to have kitchen furniture, unless the dining set is placed in the kitchen. The cabinets and drawers where you’d keep cookware and kitchen supplies are built into the house.

                Storage furniture is also not used very often, and is sort of old-fashioned. Items are usually stored in bookcases in the living room or office, in a closet, or in cardboard or plastic boxes in an attic or basement. If you need more than that, you have to get creative.

                Baby/nursery furniture often comes from a specialty store. It may or may not be available at a store that sells other types or furniture.

                  Extremely tall mattresses are popular, so headboards must also be very tall or they’d be hidden.

                  Yes, I heard about the tall mattresses somewhere before. In this context the tall headboards suddenly make sense!

                  Regarding the length and width I had a look. Turns out, sizes are in reality not that different between US and EU (specifically: Germany). Most due to rounding differences between inches and cm. Exception seems to be King Size, which is a good deal (~5 inches) wider in the U.S.

                  There being no kitchen furniture in U.S. stores also makes sense if i put down my German glasses. Our custom that the kitchen is not part of the house/apartment you buy or rent but responsibility of the person living there is probably completely uncommon not only in the U.S…

                  What you told about the storage furniture is very interesting and something I entirely didn’t know. Here it is common to have massive cabinets and wardrobes for all kind of stuff (although since the rise of Ikea, racks and shelfs also have become very popular). I assumed that to be common also in the U.S. Very interesting difference!

                  Nursery and baby stuff typically also comes in special stores here, but we normally have huge sections for children and youth (i.e. teens) furniture in our department stores.

                  So, I would say somewhat different differences than I expected, very interesting!

    My biology teacher in 7th grade during sex-ed:

    The anus is a one way road

    Fuck her homophobic ass.*

    *Not literally. Something tells me she’s not into that.

    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. An economics teacher.

      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.

            that’s very unusual! based on your instance I thought you lived in Germany, which definitely has a progressive tax system as I just described

              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…

    • The Anunnaki were ancient astronauts who visit Earth periodically, like every 10 000 years or something like that, I don’t remember the exact frequency, but they are supposed to visit us again some time in the future, when it’s their time for a new visit. They are so handsome that we can’t resist mating with them and the current human race is a cross between the Anunnaki and the humans of the last time they visited us.
    • If you travel far enough north, you will find a hidden civilization living under the ice at the North Pole that they don’t want us to know about.
