Could you create a device that would compress some substance to the extent it would reach this weight or is that impossible?

[–] lemmyng@lemmy.ca 52 points 1 day ago (6 children)

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.

[–] Umbrias@beehaw.org 5 points 1 day ago

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.
