@Adorable_Sergal@hachyderm.io It’s simply a description of reality. If something can be compressed, it means there was a lot of empty space inside it. Like foam rubber, for example. And matter can be compressed to an extreme degree. A star collapses into a neutron star by reducing its volume by 100,000,000,000,000,000 times. That’s only because the rest of its volume was empty. A rock can be compressed 100,000,000,000,000 times to have the density of a neutron star. So even rocks were largely empty.
