Several authors have even suggested that this condition should be included between the basic postulates of Quantum Theory. However, there are several scenarios where signaling is, in principle, possible: based on previous results and the analysis of the relation between unitarity and signaling we present an example of a two-particle interferometric arrangement for which the dynamics is, in principle, compatible with superluminal transmission of information. This type of nonlocality is not in the line of Bell’s theorem, but closer in spirit to the one-particle acausality studied by Hegerfeldt and others. We analyze in this paper the meaning of this non-locality and how to preserve the coexistence of the two fundamental theories in this signaling scenario.","PeriodicalId":249199,"journal":{"name":"Old and New Concepts of Physics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131884942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas other theories have been proposed in the past which realize the same, the present theory rests on basic physical principles, in contrast to for instance the MOND theory. The key to arrive at this new theory is to consider from the start the energy density of the vacuum. The way to calculate the eect of the corresponding vacuum pressure on a mass has previously been laid down by Van Nieuwenhove (1992). We obtain a modification of Newton’s law of gravitation with some peculiar properties such as the occurrence of regions of repulsive gravity. The theory can make detailed predictions about galaxy rotation curves and is also able to explain to the Pioneer anomaly.","PeriodicalId":249199,"journal":{"name":"Old and New Concepts of Physics","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115077200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CSRT is technically derived following criterion of the logical independence of the Einstein’s postulates. The epithet ”Complementary” was selected in order to distinguish the CSRT theory from alternative theories. The mission of the CSRT is not to replace the Einstein’s Special Relativity. Both of them must coexist and must have physical applications. Forasmuch as the CSRT postulates do not embody constant velocity of the light by the Einstein’s way, the CSRT need not have 4-dimensional symmetry of the Lorentz and Poincare group. Existence of the CSRT transverse Doppler eect formula and the time dilation formula for moving clocks, which are different from Einstein’s, are crucial moments of the new theory.

We assume the sign convention gμν = diag(−1, 1, . . . , 1), where μ, ν = 0, 1, . . . , D − 1. The string is described by the functions X(τ, σ), where τ ∈ R and σ ∈ 〈0, π〉.
