I applaude your enquiring mind.
No doubt our Sun seeminly will create the situation you find difficult to get around... however this flow is infinite and any local contribution will be maybe measurable or observable..Solar Wind for example clearly marks out the Heliosphere within the flow ..that is why the space craft will slow when they are really out in it... what I am trying to say is this flow is universal and the contributors every body in the Universe...
The space time "fabric" is in my view a math description of this flow really...if you see a bend in the space time grid think of the bend happening because the flow is greater in the direction of the bend... the flow is what I believe "bends" the grid.
Probably thinking of it as a directional thing is misleading becasue what we really witness is variations in flow pressure ... the push is not only down but omni directional it is the intensity that varies.
As to your last question think about the Earth travelling thru space..rotating..in the flow... it is a shield unto itself and one would think the greatest shield would be the center because we deal with the widest part or the greatest part the flow must travell past... try to see it multi directional and then consider each direction individually... consider how the one under consideration got to that point...what it travelled thru... think of standing by a mountain...it will shield a little and is then thought to have its gravitational influence..as it does but not via attraction but because it is there"...
Imaging is the only tool I have to think, imagining is useful... I do accept it is not for everyone and some folk simply do see in their mind...fortunately my imagination is fantastic...I can build anything in there and having built it it will function in "real time" and as such one can think tradgjectories how things must interact, orbit etc.
Think of it like I said... the space time grid is sort of a map of flow pressure (for mine I am sure Dr A never thought some fool like me would ever suggest such) but it fits well for me...
AND so as not to up[set folk as I do... I know what you think and that is ok...my only concern is that you do not take me any more serious than I take myself...and if I am wrong what does it matter... if I am right by the time anyonme realises the idea will be someone elses...
Its not new it is not mine property...
I like it because one does not need dark matter...dark matter takes science into the land of nonsence and someone should protest it...well I protest it because it is not needed ..accept to support the notion that attraction in fact is real...it is not.
