General Relativity Musing

Einstein, and most others who have followed, talk ( actually write) about masses ( including energy) as curving space time. I wonder if it might be more appropriate to say they alter the density of  space time. The correct general relativity solution to bending of light around masses shows twice the deflection that simply taking into account the energy (mass) of the light interacting with a Newtonian gravitational field would yield. I think this makes sense if spacetime density is increased rather than just space. I'll have to think about how to take this thought and use it to make a calculation.
