Science Daily - NYU's Dvali Says Change In Laws Of Gravity, Not 'Dark Energy,' Source Of Cosmic Acceleration:
"New York University physicist Georgi Dvali concludes that the cosmic acceleration of the universe may be caused by the modification of standard laws of gravity at very large distances, and not by 'dark energy,' as posited by many in the field. This modification, Dvali argues, could be triggered by extra space dimensions to which gravity 'leaks' over cosmic distances. Dvali's presentation took place at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington, D.C."
