Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.
A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, provides the first direct evidence of the ...

Gluons (pronounced /ˈɡluːɒnz/; from English glue) are elementary particles which act as the exchange particles (or gauge bosons) for the color force between quarks, analogous to the exchange of photons in the electromagnetic force between two charged particles.
Since quarks make up the baryons, and the strong interaction takes place between baryons, one could say that the color force is the source of the strong interaction, or that the strong interaction is like a residual color force which extends beyond the baryons, for example when protons and neutrons are bound together in a nucleus.
In technical terms, they are vector gauge bosons that mediate strong interactions of quarks in quantum chromodynamics (QCD). Unlike the electrically neutral photon of quantum electrodynamics (QED), gluons themselves carry color charge and therefore participate in the strong interaction in addition to mediating it, making QCD significantly harder to analyze than QED.
