The mass is bound to galaxies, and there is not enough gravity to do that far from black holes. David A. Smith

Smith ---------------------- Mr Smith YOU HAVE TO DECIDE ONCE AND FOR ALL WHETHER TH EPHOTON HAS MASS OR NOT OR ELSE YOU CANT MAKE REAL ADVANCE !!! 2 you understood nothing aboutthe Circlon idea !!! IT DOES NOT MOVE IN CIRCLES BECAUSE OF ANY ATTRACTION FORCE !!! IT MOVES IN CIRCLES AS AN CIRCLES BECAUSE 'I WAS BORN LIKE THAT' IOW THAT IS A *BASIC PREMISE*!!! (BASIC ASSUMPTION) as the curved space time is a basic premise th equestion is not if it is reasonable to *you* th ebasic issue is IS IT WORKING OR NOT !!! (while peole started tosuspect that the earth is orbiting the sun it was not written in any book (aactually the oppsite was written in books (:-) so some people made a premise an intuitive guess and only later it has to be found if it has legs or not by accumulating evidence that is how progress in science is done by TRIAL AND ERROR !!! and later some improvement and again another closer trial etc etc (seems that you never did such a thing i ddi things like that and it worked eventually see my model ) so j the Circlon is a by oroduct of my model so see again the circlon at the appendix of my abstarct if right the circlon is not affacted by gravitation!! THE CIRCLON IS **THE MOTHER* OF **ANY* ATTRACTION FORCE !!! see how it can be done in that abstract appendix - and try to understand something revolutionary !!! (not less revoltionary than 'curved space -time' and even better !!! .... it isa done by **mass unknown ( yet) properties -- not by empty space that has no properties by definition !!!)
