    gravitational radiation is now widely accepted, and the mathematical
    outcome of an events radiation is calculable, but why is the inverse
    square law applicable to the amplitude of this radiation?

    Anything that is spherically symmetric will obey the inverse square law as when it is moving from the centre of origin it is spreading its intensity over the surface of a larger sphere and as we know the surface of the sphere is related to its radius squared.

    i must be careful here as i dont have the facts in front of me.
    i read some time ago that a 5TH power may have a short range
    effect on the ISl for gravity, and if this effect is not found then
    certain, "extra dimensions" theories can be ruled out, i think the
    EOT-WASH group have done tests in the mm range, but im not
    sure if these tests are conclusive.
