What do you mean what mechanism? There is no "mechanism" if you do the experiment i mentioned in my post and drop a baseball or bowling ball in a out stretched blanket, (youd prolly have to have 2 people to hold the blanket up while stretching it out) the amount of distortion and dip isnt based on a "mechanism" it is purely by the mass of the bowling ball or base ball what ever you choose.
Except your experiment is nothing more than circular reasoning. It requires 'gravity' to already exist.
Space doesnt "choose" the distortion amount, the dip and distortion is a reaction based purely on how massive said object is.
So a transfer of information is not needed?
BTW, what about objects without mass? Why are you leaving them out?
what do you mean transfer of information? this isnt a mechanism.
In the example i cited, would you say the baseball or bowlingball transfers information to the blanket? No it doesnt, the blanket merely reacts based on the amount of mass.
when you lay on your matress and it indents, does your body transfer information to the matress? no it doesnt. it reacts based on you.
The world is not a giant computer program where information needs to transfer to do everything.
for every action, there is a reaction.
as far as objects without any mass (which the only thing truly without mass is light, so wow i left light out) and object without mass will not create a distortion in space time.
