        We recently moved in a very rural area. The rural carrier for our new route gave us a form to fill out, and by the end of the week we were receiving mail. UPS and FedEX on the other hand, wouldn’t deliver to us for a month. USPS will carry our packages up our driveway to our steps; UPS and FedEX throw them in the ditch by the mailbox.

        Also, did you know you can buy stamps, cards, and envelopes directly from the rural carrier? Here’s a fun quote from the rural customer registration form:

        Rural carriers maintain a supply of stamps, cards, and envelopes for sale. Additionally, your carrier will accept Certified Mail™, Registered Mail™, insure packages, and prepare money orders. Generally, rural carriers can extend practically all services available at a Post Office. Please purchase a sufficient supply of stamps and affix proper postage on all outgoing mail.

        Imagine how bleak things would be if Amazon was running the show. USPS is truly the best

          I would think Americans of every political stripe would say the post office is the best government institution we have. That tells you that attempts to undermine them aren’t in our best interest.

    He said “physically” which is wrong because Neutronium. What he possibly meant was “practically” in which Osmium would be the only element you can practically fit in the box since it isn’t possible to synthesize neutronium at that amount or handle that much safely.

      No you mean theoretical. As neutronium is a theoretical substance. To our knowledge there’s no way to find it outside of neuron stars. It is therefore physically impossible, within our current state of knowledge.

      It’s highly unlikely, bordering on theoretically impossible to assume that mankind will be able to synthesize enough to fill a cardboard box with. Then the practical side says even if that was possible, there would probably no way a cardboard box could contain that (and a plethora of other practical impossibilities).

        Wasn’t neutronium practically synthesized in miniscule amounts in the Large Hydron Collider? Also I am not a quantum physicist, so I am not sure if any neutronium is currently safe to handle beyond a miniscule amount considering a sugar cube sized amount of neutronium is theoretically the weight of a large freight ship.

      This is the case for most “Dumb laws”: there’s an outlier that becomes kinda silly, but it’s not really worth the effort to change.

    If you stuffed that box with neutronium then:

    1. Funny event: it’s so dense the Earth itself is basically a thin gas in comparison and it immediately falls through the floor, the ground, and the mantle to oscillate around in the core.

    2. Funny other event: It’s so massive it dominates gravity nearby and everything within a couple of meters gets turned into Cool Physics from aggregating onto an incompressible box really fast and hard. Maybe the nearby atmosphere ignites from being compressed into plasma against the box.

    3. Real physics step in and the neutronium immediately decompresses and the mass equivalent of an inland ocean in neutrons and angry high-energy high-mass decay products sterilizes everything through to the horizon with a gamma ray burst, also triggering massive seismic events from the blast as well as killing everything on Earth since the atmosphere is now radioactive and a lot thinner

      I’ll go one better.
      A (non-spinning uncharged) black hole with diameter 1+5/8th inches (so it fits in the box) has a mass of about 2.3 earths.

      (Near as I can tell QGP filling the whole box is around a ten billionth of that.)

      Of course the box would Very quickly no longer be outside the black hole. QGP would also cause the box to no longer be a container in short order. To put it mildly.

          You need to supercede the speed of light to exit the singularity, not enter it. Now we would see an image of the box entering the black hole on its “surface” until that faded, but the box itself would still very much enter the event horizon and be destroyed.

      Such devices exist, namely stars. Neutron stars are theorized to have neutronium at their core, essentially a soup of neutrons so densely packed that nothing else fits between them - in order words, the densest theoretical material (osmium is the densest material found on Earth).

          I wouldn’t be too surprised if you could achieve that kind of density for a few fractions of a second with explosive powered compression. I’m thinking something like the electromagnetic flux compression technique used by Nakamura et al to make the 1200T magnetic field back in 2018. The package absolutely wouldn’t exist for long though lol

          no, i mean theoretically who knows, but practically no. compressing something to be more dense than a solid is energy intense. you are surpassing the bond energy of moleculesto do it. second, compressing enough osmium is going to take less, but still bigajoules, of energy. the compressive stress is immense. anything that could hold thht stress is much too big to fit in the package.

      The surface area of the box is about 135 inches. If this surface area were spread over a sphere, it would have a diameter of about 6.5 inches and a volume of nearly 150 cubic inches (nearly twice the volume of the uninflated box!). 150 cubic inches of osmium weighs about 120lbs.

      So, indeed you could exceed the weight limit of the box by ballooning it out and filling it with something that’s at least 7/12ths as dense as osmium (or a little more dense than lead).
