It is called "frame dragging" and it is an effect predicted to occur near rotating masses according to General Relativity.
Wiki does not do justice to what a great experiment this was. I recommend checking out utube.
space sticks to matter?why?
No. Where did you get that idea from?Originally Posted by MaxPayne
The way I think of it is to consider firstly a person standing on a nonrotating planet, then a person standing on a similar rotating planet. To both of these people, the energymomentum tensor that is the source term of the Einstein equation will be to a reasonable approximation the same. In particular, both people can regard the energymomentum as purely temporal. Therefore, the deformation of the otherwise flat spacetime produced by the energymomentum source will be moreorless the same. Here, I'm applying the principle of general relativity. In the respective coordinate systems, the Einstein equation is the same (the same source term) and therefore have the same general solution. But the otherwise flat spacetime being deformed is different in the two cases. For the nonrotating planet, the otherwise flat spacetime is nonrotating, whereas for the rotating planet, it is rotating. In the nonrotating case, the exterior solution is the Schwarzschild metric, with the deformation from the Minkowskian metric being nonrotating in form. The same deformation applies to the rotating flat spacetime and has the effect of lessening the rotation of the surrounding spacetime, this effect decreasing with distance just as the gravitation decreases with distance. When this is considered in the inertial frame of reference in which the planet is rotating, the surrounding spacetime rotates with the rotation of the planet.
This can also be viewed as an example of Mach's principle where in the frame of reference of the rotating planet, the planet is not rotating and the planet imposes some of this nonrotating character onto the surrounding spacetime. But further from the planet, this effect diminishes and the rotation of the flat spacetime increasingly dominates. In the frame of reference of the nonrotating distant spacetime, the spacetime surrounding the rotating planet has some of the rotation of the planet.
