Unless your theory has RoS. Sure you do get isotropy of the speed of light without the RoS. Why? Because speed is a ratio of length/absolute time content for a clock second. RoS destroys isotropy by asserting that light from the front is arriving at M' at c+v and from the rear arriving at M' at c-v. > > Tell me .. if you have two synchronized clocks together, and then you move > them apart with the same speed but opposite directions and then bring them > to a halt .. does your theory say they will remain synchronized? Sure my theory agrees with SR that they will remain synchronize.

These theories share the property that the round-trip speed of light is isotropic in any inertial frame, but the one-way speed is isotropic only in an æther frame. In all of these theories the effects of slow clock transport exactly offset the effects of the anisotropic one-way speed of light (in any inertial frame), and all are experimentally indistinguishable from SR. All of these theories predict null results for these experiments. See Test Theories above, especially Zhang (in which these theories are called Edwards frames). Cialdea, Lett. Nuovo Cimento 4 (1972), pg 821. Uses two multi-mode lasers mounted on a rotating table to look for variations in their interference pattern as the table is rotated. Places an upper limit on any one-way anisotropy of 0.9 m/s. Krisher et al., Phys. Rev. D, 42, No. 2, pg 731734, (1990). Uses two hydrogen masers fixed to the Earth and separated by a 21-km fiber-optic link to look for variations in the phase between them. They put an upper limit on the one-way linear anisotropy of 100 m/s. Champeny et al., Phys. Lett. 7 (1963), pg 241. Champeney, Isaak and Khan, Proc. Physical Soc. 85, pg 583 (1965). Isaak et al., Phys. Bull. 21 (1970), pg 255. Uses a rotating Mössbauer absorber and fixed detector to place an upper limit on any one-way anisotropy of 3 m/s. Turner and Hill, Phys. Rev. 134 (1964), B252. Uses a rotating source and fixed Mössbauer detector to place an upper limit on any one-way anisotropy of 10 m/s. Gagnon, Torr, Kolen, and Chang, Phys. Rev. A38 no. 4 (1988), pg 1767. A guided-wave test of isotropy. Their null result is consistent with SR. T.W. Cole, Astronomical Tests for the Presence of an Ether, Mon. Not. R. Astr. Soc. (1976), 175 93P-96P. Several VLBI tests sensitive to first-order effects of an æther are described. No æther is detected, with a sensitivity of 70 m/s. Ragulsky, Determination of light velocity dependence on direction of propagation, Phys. Lett. A, 235 (1997), pg 125.

One-way isotropy is not the same as one-way measurement for the value of the speed of light.
