    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 neutroniun at that amount or handle that much safely.

      I guarantee that it is physically impossible to fill a cardboard box with pure neutronium. Is it physically possible to get over 70 lbs of the stuff in there in a stable, shippable manner? I don’t know, and neither do you. It’s certainly far, FAR beyond the capability of any technology on Earth, but I guess it might maybe possibly not break the laws of physics. I can’t prove that though, and neither can you, so neither of us can actually prove the statement wrong.

      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).

      To be clear, the neutronium you’re talking about here is the one that is theorized to exist at the core of neutron stars? Could you elaborate on how much has been synthesized and could be handled safely?

        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.

        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’m sorry you are only subscribed to Amazon letter prime, in order to get your packages you must collect them from your nearest whole foods or upgrade to prime plus.

          We’re sorry prime plus is not available in your service area.

          I would expect better from UPS, and as usual the USPS surprises me with their quality.

          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.

        For those of us that don’t use arbitrary made up units at all, that’s 1.35515609E+34 Planck Length x 8.477460474E+33 Planck Length x 2.555613997E+33 Plank Length.

        True but if it is 71 befor putting it in…

        Inside the box it can stay 71 or… loose fat to 35 . You can only know by picking up the box.

    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

    It’s because all the packages have the same domestic weight limit.

      Okay so I originally assumed this was probably due to some union rule or something like that. But I didn’t find any reference to it in the NALC guidelines, anything in the USPS resources center (which is hard to use), anything in google searches, and the original employee documentation or spec.

      I did find the USPS History section and it turns out they have someone whose job title is “Postal Historian”, Stephen Kochersperger.

      But, anyways, I found the address (not email of course haha) for the USPS history office so I have wrote up an letter and put it in the mailbox. I will eventually update yall

      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.

      I saw one “It’s illegal to hunt Blue Whales in Idaho”. Because it’s illegal to hunt endangered species in Idaho, and Blue Whales are endangered, not because legislators were super concerned about saving Idaho’s whale population.

        Was shooting the shit with a customer who was bitching about grass seed bags being full of inert materials. Had no idea! Another customer chimed in that the extra crap is to help if feed properly in a spreader.

      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.

        Wouldn’t the box forever be outside the black hole… as in just on the surface as it would need to exceed the speed of light in order to actually enter the event horizon?..or is that our of date knowledge?

          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.
