Space-Time............

[Harlequinne]

If Space-Time is curved,where does the vacuum fit into all of this?

Is it fair to say,that a ball 'rolling' around the Sun,must have been a fair amount of logical acrobatics on Einstein's part,but it still remains to be said that the warping could be in any direction,and not necessarily horizontal?

So,which way does the Orbit take place? Where is the warping? Why not have Vertically Orbiting paths?

Have you seen the experiment where two spheres are hung from a ceiling by steel thread? The balls seem to attract. Could it be then, that circle and sphere are indistinct? And that could also account for warpage!

Affirmatives.

Your choice of coordinate system is arbitrary — we choose to look at the warping in the plane of an orbit because that's where we observe the effect, and the motion of an object defines a plane. It would be there if we chose another plane.

There is no up or down in spacetime. Direction is omnipresent in spacetime because everything is relative.

I am working on another eighteen relativity's as we speak
