The graviton could be between and outside quarks and gluons.

The idea is that the graviton is like a small black hole where the energy pikes are leaving from its poles. When those energy pikes impact quarks and gluons they surrender those particles like plasma fields surrounding planets. 

And that means the graviton would be like a tensor between quarks and gluons. The energy pikes from quarks and gluons are taking energy outside that quantum field that surrounds them. 

That model explains why electromagnetic interaction and weak nuclear force are so powerful when we compare them with gravitation. The dimension of tensor between quarks and gluons is very small. In comparison to the area of the quarks. 

Protons and neutrons are involving three quarks. And gluons between them. Normally we can say that strong nuclear force keeps those particles in one entirety. 

But how to describe the strong nuclear force? There is some kind of electromagnetic- or quantum vacuum. That keeps those particles together. So there are two possible points where we can find graviton. 

There is the possibility that there is some unseen particle between gluon and quarks. And maybe the electromagnetic underpressure of that particle that can be the graviton pulls quarks and gluons together. Or there is another interesting possibility. That possibility is that gluons are also gravitons. 

Three quarks, that strong nuclear interaction connects with gluons are formin protons and neutrons. When those baryons are spinning the structure of those quarks is sending wave motion along with tensors that are connecting gravitons to gluons. 

The dimension of the wave motion that the quarks are sending is far bigger than the dimension of the wave motion that leaves from the tensor. And that causes the gravitation to be so weak. 

When energy pikes that are leaving from those tensors are traveling through the universe they are forming extremely thin pikes. Those pikes can affect a longer range than wave motion that leaves from quarks. The electromagnetic turbulence destroys the energy waves that are leaving the quarks. 

The reason why the energy waves that source is in tensor travel to higher distance is that they are hitting each other less frequently than wave motion that leaves from quarks.
