Is Gravity Truly Omnipresent and Can It Exist Without Mass?

[Jake Minneman]

If Gravity is considered one of the four fundamental forces why is it not itself omnipresent? The other three forces are variables that do not rely on the existence of another thing, but in the case of gravity mass is essential to its creation. Could the force gravity exist without massive objects warping the fabric of space? When I enter space do I warp the fabric of space? If so could objects on the molecular scale revolve around me?

I did not know what section this belonged in so...

As a refutation classical electric fields require the presence of charge which is "another thing".

To be fair, electromagnetic waves can exist without any charges at all. But then again, so can gravitational waves exist without any mass.

I'm not answering this question but really expanding it from my own ignorance ... what I don't understand, but what you are stating as fact, is that the other forces exist without the presence of another thing. I always thought that the strong and weak forces were forces that interact among subatomic particles. If that IS the case then what does it mean to say that these forces exists without at least two things for them to interact between? If the strong force is mediated by gluons, how is that different from gravity being mediated by gravitons? I am NOT trying here to refute what you are saying, I just don't understand it so am using it as a springboard for the related question of "do the other forces in fact exist in the absence of other things in any way differently than gravity does?".
