I'm cautiously optimistic, but let's be a bit more reserved on this until we see it properly peer reviewed. This area is ripe for pathological science and a myriad errors induced by human factors.

Hopefully other labs around the world will be able to duplicate the experiment soon. We'll see if the results are as well.

I may be misreading, but isn't the "real story" that they ran essentially the "gravity probe B" experiment on the ground and generated data despite all the noise sources and interference and all that on the ground?

Its pretty impressive technologically to pull that off. Don't have to worry about seismic noise when you're on a space satellite, for example.

But this is what concerns me as well. Yes, the effect is significantly - several orders of magnitude - greater than what the theory predicted, however there's no reassurance that it's outside local noise in the lab. "Gravity probe B" was extraordinarily sensitive and safely outside local noise.

I suppose the next step in testing this effect would really be to try it in space.
