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 guess I forgot to say it needs to fit in the package lol. I know it’s possible in extreme environments but can you create such an environment in this package is the question.

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.

Just toss a few teaspoons of black hole in there.

Just have the package delivered to the black hole and watch usps get it there rain or snow

Where the fuck did USPS get those super-powerful electromagnets from and how do they know to use them to manipulate impossibly heavy packages!?!

The alien USPS mail sorter from the movie Men in Black II.
No idea, man. I just saw that thing in the company warehouse and started pressing buttons
