Moon measurements might explain away dark energy (moved from ATSNN), page 1

Plans to orbit the moon may explain why the universe is rapidly growing. This may also put a wedge in Einstein's theory of gravity.

Plans to trace the Moon's orbit with extraordinary new accuracy could reveal kinks in Einstein's theory of gravity and help explain the mysterious accelerating expansion of the universe, says a US researcher.

The acceleration cannot be explained by known forces in the Universe. To account for the behaviour, cosmologists have introduced the concept of a new, as yet unseen, force - dark energy.

"The accelerated universe can be a window of opportunity for understanding the most fundamental aspects of gravitation, and may signal the modification of standard laws of gravity at very large distances," Dvali told an audience at the American Association for the Advancement of Science meeting in Washington DC.

This could lead to new explanations about the moon's gravity, if it is funded, and could lead to a new revelation about the moon and the speed of the expanding universe.
I think we could learn many things from this experiment if the funding goes through.
