Gravity Leakage: Energy Accounted for in LHC Predictions?

If people were going to do test runs and predictions, how would they fair before the process is up and running?

Lubos Motl:

What does he say about the cosmological constant? Well, it does not exist. The accelerating expansion of the Universe is, Dvali argues, due to a "leak of gravitational force" into extra dimensions that only appears at very long distances.

So how is this supposed to support views of the space allocated to the views of a bulk with possibilties of expression, if contained in the graviton gatherings? How would high energy support the new visionary aspects of langrange points knowing that Gia has a way to measure. Would this support Gia's views?

Leaking Gravity May Explain Cosmic Puzzle

Dvali would modify the theory of gravity so that the universe becomes self-accelerating, eliminating the need for dark energy. He presented his work here earlier this month at the annual meeting of the American Association for the Advancement of Science.

Dvali borrows from string theory, which states that there are extra, hidden dimensions beyond the four we are familiar with: three directions and time. String theory suggests that gravitons -- hypothetical elementary particles transmitting gravitational forces -- can escape to other dimensions. Dvali says this would cause "leaks" in gravity over cosmic proportions, reducing gravitational pull at larger distances more than expected.

"The gravitons behave like sound in a metal sheet," says Dvali. "Hitting the sheet with a hammer creates a sound wave that travels along its surface. But the sound propagation is not exactly two-dimensional as part of the energy is lost into the surrounding air. Near the hammer, the loss of energy is small, but further away, it's more significant."
