Doesnt the idea of gravity leakage between dimensions explain more than one unanswered question right now. & if not then gravity shielding, Im talking pricipally about the expansion of the universe, & the fact that the community is frantically trying to discover dark matter to explain it.

Please show your work. Got any numbers for us?

Crank ... yes you are.

C.duffill ... If M-Theory is correct, if there are additional dimensions, it offers a possibility of explaining many things: Gravity leakage being only one of them.

But keep in mind that extra dimensions does not guarantee that they are affected by gravity ... though it is likely.

Where are your compactified dimensions hiding?

If there are extra dimensions then they have a characteristic scale. Center of mass gravitational attraction within factor of 10 of the largest compactified dimension will show measurable deviation from 1/r^2 dependence as the leak is excluded.

At a center of mass separation of 20 microns, gravitation is still cleanly 1/r^2,

Spiral galaxies have too much gravitation, not too little.

1. They need not be compaticified.
2. They might be and exist only at the Plack scale
3. They do not need to interact with either time or gravity.

Questions exist ... answers do not. Be patient.
