This is: where is mass? How is mass? Is it contained all around the matter, in each particle? If so, where is the mass distributed around each particle?

Relativity establishes that at light speed, an object has infinite mass and exists in a place where time stands still. Relativistic effects resulting from high velocity do not kick in appreciably until one approaches it very nearly. The angular spin momenta of particles approach this velocity and not only contributes to mass but time as well.

As for string theory, I see it as the fundamental law to which particles subscribe. We just can't analyze deeper than strings. After all, quarks and gluons etc have to be made of energy with a common origin and that origin is strings. m-theory fits in nicely with the beginnings of creation as I've described it in my TOE.

But I believe in such case we wouldn't call gravitons gravitons, but another thing.

I thought very much the same thing even as I was writing it, but I wrote it anyway because I thought the matter academic in a playful sort of way.

I don't think that Maxwell-Newton displace or exclude Relativity-QM in the least. The equation (m1m2)/d² applies regardless of the actual nature of the forces that bring two objects in space together.
