How do planets orbit in the same plane if the orbital space is curved by the sun ?
If the space in our solar system is curved by the sun's mass, and planets orbit on said curvature of space-time, then how is it possible that the planets orbit in the same plane ? Which is flat.
If Einsteins theory is correct, then no such flat plane should exist in our solar system. And the planets orbits should be on a curved space instead of a flat space, with their orbits stacked one on top the other as they fall deeper and deeper in the 'curvature of space-time'. Like in the illu
It is important to distinguish the measure and the measurand in all circumstances.
That is the ruler is not the same as that which is being measured.
Failure to do this leads to much misunderstanding.
Here are two 'straight line' graphs.
Or are they ?
Straight is the one dimensional version of not curved or zero curvature.
