This is the requirement of the Wheeler-Feynman absorber theory of radiation. The condition for complete absorption is more or less written down immediately, and the various cosmological models tested by inspection. Some of the existing errors concerning the refractive index of the intergalactic medium and the past absorber are examined in some detail. Of the Friedmann cosmologies, only the oscillating models are opaque. A number of ever-expanding nonrelativistic cosmologies such as the Dirac and the latest Hoyle-Narlikar models, are also opaque. An assessment of the present value of the Wheeler-Feynman theory is given in the light of recent work on its quantization.","PeriodicalId":54612,"journal":{"name":"Physics-A Journal of General and Applied Physics","volume":"1 1","pages":"1722-1737"},"PeriodicalIF":0.0,"publicationDate":"1972-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88141193","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}

From an examination of the commutation relations between Pmu =-i( delta / delta xmu ) and Anu , P.A A.A, etc. one finds a new set of 'translation' operators Pi mu which commute with the total 'Hamiltonian'. The authors then construct a representation of the Poincare group out of the Pi mu and their canonically conjugate 'coordinates' Qnu . The solutions are shown to correspond to the spin zero mass m representation of the restricted Poincare group. Applications of the technique to other quantum-mechanical problems are also briefly discussed.","PeriodicalId":54612,"journal":{"name":"Physics-A Journal of General and Applied Physics","volume":"10 1","pages":"1658-1663"},"PeriodicalIF":0.0,"publicationDate":"1972-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81980950","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}
