The problem with the relativistic 'space warp' idea is that it makes
perfectly circular orbits possible, which aren't in this universe. Nor
can you say that the Sun's 'warp' causes inertia, because if it did,
then inertia would only exist when you thrust away from the Sun. 

As I've said before, I do believe that Mach's Principle is involved
here. If inertia is the distant stars reaching out gravitically through
space and time (requiring that gravity to go forward in time then back
so as to resist your push when you push), then it is entirely possible
to do the same back, because this inertia theory demands that time is
symmetrical both ways. Physicists can't have their cake and eat it.

Space that you talk about warping exists because mass exists. If there
were no mass, there would be no space. I'd suggest looking into Cravens
5-D mathwork a bit more.
