# Is GR flawed

Is GR flawed?
There are at least two inconsistencies that stand out:
1. An object approaches a star's gravity well. The linear momentum of the object is such that it becomes a satellite. As the satellite tends toward the star, from where is its momentum replenished, to keep it in orbit?
2. What is the force applied to the satellite that causes it to follow the space-time gradient toward the star. If gravity is a result of the curvature of space-time, from where does that force come ---since there is no tether (action at a distance) pulling them toward each other?

Hi Zanderbaxa,

This may help resolve some of the issues.

It what causes the is similar to Newton. That is, it more specifically describes how; but it does not explain the mechanism by which mass contorts space time. Ibo other words, what causes the particle to slide down the parabolic surface?

I do not think it is arcane as EFE; but time will tell.

One thing is for sure EFE is definitely arcane from my point of view.
