From almost any perspective, a meteor (or any object) in space is always falling in one direction or another.
The "almost" comes in because there is zero gravity at the exact center of any body, where the pull is equalized from all directions.
I'm not too clear in this one, but the other "almost" is that gravity (except for external fields) does not exist in a hollow sphere since wherever you put an object inside this sphere, all the gravitational forces from the mass of the sphere's "walls" cancel out.

http://hyperphysics.phy-astr.gsu.edu/hbase/Mechanics/sphshell2.htmlA gravity "neutral point" is also true of any two bodies in an otherwise "sort of" gravity-free volume. Even Jules Verne knew this in his "From the Earth to the moon," where at one point the pull from the earh was canceled out by the pull of the moon.*
It's also true for any number of bodies. Considering the same principles involved in the cited article about hollow spheres, for any N bodies, there must be a point somewhere between them where the pull from each of them acting at one particular point cancels out.
I surmise, therefore, that there may be many volumes (as opposed to "areas") in the cosmos (
including the centers of black holes) where this situation pertains.
I was trying to put these conceptions into a theory of "dark matter," but I don't have the background to make it all "click."

*Yeah, I know, they should not have felt any "weight" at all after the initial acceleration and final deceleration, since they would be in free fall all the way. But Verne knew about that equalization point.
