I came across this:
The First Test That Proves General Theory of Relativity Wrong - A spinning top increases its weight much more than expected
And I was wondering what impact this has to the General Theory of Relativity.
According to Einstein's theory of general relativity, a moving mass should create another field, called gravitomagnetic field, besides its static gravitational field. This field has now been measured for the first time and to the scientists' astonishment, it proved to be no less than one hundred million trillion times larger than Einstein's General Relativity predicts."We ran more than 250 experiments, improved the facility over 3 years and discussed the validity of the results for 8 months before making this announcement. Now we are confident about the measurement," says Tajmar.This may be the first empiric clue for how to merge together quantum mechanics and general theory of relativity in a single unified theory.What could this other effect be? They thought maybe it's the gravitomagnetic field – the fact that the spinning top exerts a higher gravitational force. So, they placed around the spinning superconductor a series of very sensible acceleration sensors for measuring whether this effect really existed. They obtained more than they bargained for!I basically quoted all the most important stuff here. I was hoping this could be an interesting topic.Now, it remains the need for a proper theory. Scientists can also now check whether candidate theories, such as the string theory, can describe this experiment correctly. Moreover, this experiment shows that gravitational waves should be much more easily to detect than previously thought.
I also hope this isn't old stuff...
