I don’t know why so many people on Lemmy seem to think that when capitalism dies a fully formed socialist utopia will magically spring up in its place. The way we’re headed when capitalism dies the people with all the guns will be in charge, and that’s mostly the same people who already are. The end of the American republic probably won’t be the end of the American empire.
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.
