Uvazhaemyi gospodin Sumarokov!
_Pokazatel' perelomleniya <...> zavisit ot togo, naskol'ko sil'no padaet skorost' rasprostraneniya elektromagnitnoi volny v veshestve, otnositel'no vakuuma._ -- Sovershenno verno! Pozvolyu sebe napomnit' vam, chto gravitacionnoe pole ne veshestvo i skorost' raspredeleniya sveta kak v pole, tak i bez polya, odna i ta zhe (poskol'ku eto vse ravno vakuum, eto odna iz aksiom teorii otnositel'nosti, proverena opytom Maikel'sona-Morli). No togda, prodolzhaya Vashu logiku, gravitacionnoe pole ne mozhet iskrivlyat' hod luchei. Vrode tak. Po-moemu, eto neplohoi primer togo, chto gravitacionnaya linza vse zhe po svoei fizicheskoi prirode otlichaetsya ot steklyannoi.
_Rezonansnaya chastota,sushestvuet mezhdu samimi atomami veshestva, no ona, ni v koei mere ne svyazana s samim koefficientom perelomleniya._ -- Net. Pochitaite Feinmana, on ochen' krasivo opisyvaet etu svyaz'. V obshem-to, eta svyaz' opisyvaetsya i v obychnom universitetskom kurse elektromagnetizma ili optiki.
_vliyanie mezhgalakticheskogo gaza, kak gravitacionnoi linzy, budet bolee ravnomernym, chem vliyanie zvezdnogo skopleniya._ -- Da, konechno. No, kak ya napisal vyshe, avtor stat'i, po-moemu, pereputal chto-to, kogda napisal, chto osnovnaya massa nahoditsya v galaktikah.
Vashu stat'yu posmotryu chut' pozzhe, nu i kommentarii po ee povoru na etoi vetke diskussii byli by lishni.
S uvazheniem, Dima
