I was wondering if anybody knows the status of the work of C. S. Unnikrishnan in respect to a paper he wrote entitled http://arxiv.org/PS_cache/gr-qc/pdf/0406/0406023v1.pdf" [Broken]. Extract taken from the abstract: “In this paper I argue for a reassessment of special relativity. The fundamental theory of relativity applicable in this Universe has to be consistent with the existence of the massive Universe, and with the effects of its gravitational interaction on local physics. A reanalysis of the situation suggests that all relativistic effects that are presently attributed to kinematics of relative motion in flat space-time are in fact gravitational effects of the nearly homogeneous and isotropic Universe.” C. S. Unnikrishnan is an associate professor at the http://www.tifr.res.in/" [Broken] might give those with the necessary background in this subject a more immediate insight to the scope of his work. Extract taken from last page: “Consider two clocks in a laboratory that are moving very fast inertially. Then one of the clocks, B, is transferred to another laboratory that decelerates and stops, say relative to the reference markers provided by the distant stars or the CMBR. (A) proceeds along its inertial motion. Finally B accelerates again such that it comes to rest relative to A. In the special relativistic analysis of this problem, it is the accelerated clock B that ages less, since the physical situation in a space-time diagram from A’s frame is identical to that in the original twin paradox." In this introduction, he seems to raise some fairly reasonable questions about the twin paradox in respect to Einstein’s first explanation back in 1918 plus the subsequent spread of interpretations based on accelerated frames, lines of simultaneity and time encoded light beams etc.
