| | Quantum Chromodynamics (QCD) |
 | | On the other hand, the QCD gluons are massless, and their strong interaction is not damped by a small parameter. |
 | | As a result, the QCD vacuum polarization effect is extremely strong, and the empty space is not empty at all - it must contain a soup of spontaneously appearing, interacting, and disappearing gluons. |
 | | There are at least seven levels in between: nucleons are built of quarks, nuclei of nucleons, atoms of nuclei and electrons, molecules of atoms, amino acids of molecules, proteins of amino acids, and we did not arrive at a cell yet. |
