I don't know what gravity is in its entirety but I suspect that its force is spread through out 11 dimensions thereby making it less powerful than the electrodynamic and strong and weak nuclear forces that are evidenced in our familiar 4 dimensions and includes a anti gravitational component related to what we currently call dark energy and dark matter.

I suspect that gravity may even be able to leak from one brane in a multi universe system into another.



At least the evangelical explaination of gravity has more certainty and elegant simplicity: 'Gravity is whatever God wants it to be'
