11. Therefore, not only the two-way speed of light but also the one-way speed is anisotropic in moving frames . 12. A moving frame , in these circumstances, is just that : a frame which varies from point to point. 13. More generally, moving frames may be viewed as sections of principal bundles over open sets " U ". 14. Astronomers believe the Milky Way is moving at approximately with respect to this local co-moving frame of reference. 15. Broadly speaking, a moving frame corresponds to an observer, and the distinguished frames in special relativity represent inertial observers. 16. Lorentz showed that the dimensions of electrostatic systems in the ether and a moving frame are connected by this transformation: 17. Equivalently, to find a way to assign coordinates so that they coincide with the coordinates corresponding to a moving frame . 18. However, in relatively moving frames the object's endpoints have to be measured simultaneously, since they are constantly changing their position. 19. It shows that temperature separation in a moving gas is due only to enthalpy conservation in a moving frame of reference. 20. It can be seen that the torque is not zero, which apparently would cause the lever to rotate in the non-co-moving frame .
