Hi Kevin,
There have been some lively discussion within the UT forum, regarding concepts of space and time, including the possibility of speeds greater than light. In response to an interest within the UT membership about Einstein's universe, I started posting the weekly update provide by the folks running the Gravity Probe B mission.
The Gravity Probe B mission is an experiment to test Einstein's theory regarding frame dragging of space caused by a rotating mass like earth, as it passes through space at around 70,000 miles per hour. I expect that Einstein's theory will be proved, but I'm hoping something new might be learned to advance our understanding of the universe.
Regards,
