The quantum reason behind the solidity of matter
Briefly

Atoms, despite being mostly empty space, result in solid objects that are impenetrable. This phenomenon is explained through quantum physics, highlighting the remarkable nature of atomic structure.
Atoms are made of a large nucleus composed of protons and neutrons, with a tiny size compared to the overall atom. This internal structure leads to a paradox where mostly empty space forms solid, impenetrable objects.
