Speed of Gravity: oshibka Van Flandern?
2.06.2004 10:26 | P. V. Putenihin

V rabote Van Flandern The Speed of Gravity - What the Experiments Say est'  
takoi fragment: 
By direct calculation from geometric ephemerides fitted to such observations,  
such as those published by the U.S. Naval Observatory or the Development  
Ephemerides of the Jet Propulsion Laboratory, the Earth accelerates toward a  
point 20 arc seconds in front of the visible Sun, where the Sun will appear to  
be in 8.3 minutes.  
Menya zainteresovalo sleduyushee mesto v etoi fraze (nekvalificirovannyi perevod  
moi):  
Zemlya prityagivaetsya k tochke v 20 dugovyh sekundah vperedi vidimogo polozheniya  
Solnca, tochke, gde Solnce budet vidimym cherez 8.3 minuty. 
Oznachaet eto ni chto inoe, kak podtverzhdenie togo, chto skorost' gravitacii  
zavedomo prevyshaet skorost' sveta. Esli priznat', chto eta 20-sekundnaya tochka  
sovpadaet s fakticheskim polozheniem Solnca, to my poluchim beskonechno bol'shuyu  
skorost' rasprostraneniya gravitacionnogo vzaimodeistviya. Ob etom Van Flandern  
ne upominaet. Poprobuem hotya by ocenit' znachenie skorosti gravitacii ishodya iz  
privedennyh dannyh. Vvedem sleduyushie oboznacheniya: Ts  vremya prohozhdeniya  
Solncem dugi ot vidimogo polozheniya do fakticheskogo s uchetom skorosti sveta;  
Tg  vremya prohozhdeniya Solncem dugi ot tochki, k kotoroi prityagivaetsya Zemlya v  
moment izmereniya, do fakticheskogo polozheniya Solnca. 
Ochevidno, chto s dostatochnoi stepen'yu tochnosti Tc = 8.3 minuty. Vremya  
prohozhdeniya vtorogo uchastka traektorii Tg neobhodimo izmerit'. 
Ne vyzyvaet somneniya, chto  raschetnoe fakticheskoe polozhenie Solnca (a ne  
izmerennoe po gravitacionnomu prityazheniyu!) nahoditsya vperedi vidimogo  
polozheniya Solnca. Poetomu sleduet ubedit'sya, chto izmerennoe teper' uzhe po  
gravitacionnomu prityazheniyu polozhenie Solnca deistvitel'no nahoditsya vperedi  
vidimogo polozheniya Solnca. Predpolozhim, chto tochnost' izmereniya sostavlyaet 50%.  
To est', fakticheskoe gravitacionnoe polozhenie Solnca nahoditsya v tochke dugi 30  
sekund (pogreshnost' mozhet byt' tol'ko v plyus). Sledovatel'no, v moment  
izmereniya gravitacionnoe Solnce proshlo put' po duge za 8.3/3  menee, chem 3  
minuty. Sootvetstvenno, do Zemli gravitaciya ot etoi tochki takzhe doshla za eti 3  
minuty, to est' skorost' gravitacii pri takoi plohoi tochnosti izmereniya v 3  
raza vyshe skorosti sveta. Odnako oboiti molchaniem takoe gruboe izmerenie  
slozhno, i Van Flandern kak by podrazumevaet, chto gravitacionnoe polozhenie  
Solnca sovpadaet s istinnym. Esli zhe dopustit' tochnost' izmereniya 10%, my  
poluchim znachenie skorosti gravitacii v 10 raz vyshe skorosti sveta. 
Togda chto zhe izmereno v eksperimente Kopeikina? Vozmozhno tol'ko dva otveta:  
libo Van Flandern nepravomerno ssylaetsya na izmerenie gravitacionnogo  
polozheniya Solnca, to est' eto izmerenie ili oshibochnoe, ili net ego vovse, ili  
interpretaciya izmerenii oshibochna; libo vse to zhe samoe mozhno skazat' ob  
eksperimente Kopeikina po izmereniyu skorosti  gravitacii (skorost' gravitacii  
s priemlemoi pogreshnost'yu ravna skorosti sveta). 
Iz dvuh vzaimoisklyuchayushih utverzhdenii odno, bezuslovno, lozhnoe. Chto mozhet  
skazat' prosveshennaya obshestvennost' ob etih dvuh eksperimentah? Citiruemaya  
stat'ya nahoditsya na saite www.metaresearch.org.
