Why is gravity "special"?
(You may think this belongs in the General Relativity section, but the question really relates more to particle physics).
As I understand it, anything with any energy whatsoever creates a disturbance in the gravitational field. So this means that the potential energy from interactions via W bosons, Z bosons, gluons, or photons all have effects on gravity (even if those effects are so small as to be undetectable).
On the other hand, the fields due to other forces (strong, weak, and electromagnetic) are -- as far as I know -- affected ONLY by the particles that correspond to those fields. In other words, no amount of charge is going to affect the strong force.
I'm not great at lucidly describing what I mean so I hope someone sees what I'm getting at. Can someone help explain this?
Thanks
