|Einstein's theory of general relativity anticipated that the space-time around Earth would be not only distorted but also warped by the planet's rotation. Gravity Probe B showed this to be accurate.|
Study leader Robert Nemiroff, of Michigan Technological University, said in a report. "If foaminess exists at all, we think it must be at a scale far smaller than the Planck length, indicating that other physics might be involved," (The Planck length is a nearly unimaginably small distance, about one trillionth of a trillionth the diameter of a hydrogen atom.) Nemiroff added "There is a possibility of a statistical fluke, or that space-time foam interacts with light differently than we imagined," If the study holds up, the implications of this study are huge, researchers said.
Bradley Schaefer of Louisiana State University said "If future gamma-ray bursts confirm this, we will have learned something very fundamental about our universe,"
