Hi , I have a question that arose in mind. If gravity is a spacetime curvature just like GR says it is the I guess the only way to altering it is from the physical size/density of the object curving the space fabric, like sun being bigger having higher gravity and so on. But if we find that gravity is like electromagnetic force , could we be able to adjust it just like we can make different kinds of strenghts of the electromagnetic force like in an electromagnet. In the case of the existance of graviton I guess. Please explain this to me , because i feel like getting something wrong here or maybe not...? Thanks in advance for your 2cents of input :) Girts.
