There are a few questions on here about why Gravity is not a force, but I'm having trouble grasping why exactly.
It sounds to me that Gravity is not a force because it is simply a by-product of mass on spacetime. How does this differ from the strong nuclear force? Are the other forces not an effect of the presence of a particle?
I apologize if this is an overly simple question, I'm not well-versed in physics.
