i am curious as to something i heard about micro-gravity. If spacetime has a certian elasticity such that only objects of a "particular mass or graeter" have an effect on it. If i think of it as a bed sheet with a marble placed on it the sheet bends but if i put only a thin piece of plastic on...

I am curious if there has been any research into the elasticity of spacetime in regards to mass. If we consider that a fabric is resistive to a degree to an object it could be said that an object must poses a certain amount of mass before it can cause a divet in spacetime.

I would say that if the mass of the proton is equal to zero and you follow the basic rules of multiplication the answer is there. However i believe you ask the question under the assumption that the photon must have mass. E is equal to the mass times the speed of light squared would also mean...
