The glue that binds us all: lifting the veil on emergent universal dynamics in nature's strong force at high energies

Massless gluons are responsible for nearly all of the mass of the visible universe. After a brief survey of their remarkable 
properties, we outline how gluon matter at high energies can be described by a strongly correlated many-body theory with universal dynamics 
that bears striking parallels to systems in statistical mechanics and to a memory effect carried by  gravitational waves. When heavy nuclei collide at ultra relativistic energies, 
Weibel-like instabilities drive the matter to decohere and flow to a nonthermal fixed point before forming a perfect fluid on parametrically long time scales. 
This nonthermal fixed point of the hottest terrestrial fluid (T= trillion Kelvin) is universal and can be quantum simulated by cold atomic gases (T=nano Kelvin).
