Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity.

Seems like a credible source anyway. This is pretty interesting, as it is an aspect of relativity that it turns out I know nothing about. Most things on this subject are garbage; people saying they create anti gravity machines by arranging some magnets in a clever way. I didn't know that a spinning superconductor could actually create measureable gravitational effects. But apparently such effects are predicted by GR.

 

It also turns out that "frame dragging" is also associated with this "gravitomagnetism".

 

So yeah. I found it neat anyway.

lol...there's an identical thread about this that was just made by Bascule.

Oh well.
