Leaking Gravity may explain acceleration without invoking "Dark Energy" or other epicyclic "cosmic constant" variables
"Scientists may not have to go over to the dark side to explain the fate of the universe."
- (*groan*) In over-simplification, the extra dimentions of space, albeit small ones, that are implied by string theory may provide the extra volume required for gravity to degrade faster than R^-2. Leftover hardware from Apollo mission on Moon may provide a suitable experimental base to test this prediction.
