1 GRAVITATION XLAIND BY TH THORY OF INFORMATONS Antoine Ake * ABSTRACT The theoy of infomatons explains the avitational inteations by the hypothesis that infomation is the substane of avitational fields The onstituent element of that substane is alled an infomaton The theoy stats fom the idea that any mateial objet manifests itself in spae by the emission of infomatons: anula mass and eney less entities ushin away with the speed of liht and ayin infomation about the position ( -infomation ) and about the veloity ( -infomation ) of the emitte In this atile the avitational field is haateised; the laws of avito-eletomanetism ae mathematially dedued fom the dynamis of the infomatons; the avitational inteations ae explained as the effet of the tend of a mateial objet to beome blind fo flows of infomation eneated by othe masses; and avitons ae identified as infomatons ayin a quantum of eney INTRODUCTION Daily ontat with the thins on hand onfonts us with thei substantiality An objet is not just fom, it is also matte It takes spae, it eliminates emptiness The amount of matte within the ontous of a physial body is alled its mass The mass of an objet manifests itself when it inteats with othe objets A fundamental fom of inteation is avitation Mateial objets (masses) ation at a distane on eah othe: they attat eah othe and if they ae fee, they move to eah othe alon the staiht line that onnets them Aodin to the lassial theoy of fields, the avitational inteations an be desibed by intoduin the avitational field : eah mateial objet manifests its substantiality in spae by eatin and maintainin a veto field and eah objet in that field expeienes a tendeny to hane its state of motion The field theoy onsides the avitational field as the mathematial entity that mediates in the avitational inteation This is futhe developed by Olive Heaviside () and Ole Jefimenko () In the theoy of avito-eletomanetism (GM) they desibe the avitational field statin fom the idea that it must be isomophi with the eletomaneti field This implies that it should be haateized by two vetoial quantities that ae analoue to espetively the eleti field and the maneti indution B, and that the elations ovenin these quantities should be analoue to Maxwell s laws * antake@skynetbe - wwwantoineakenet Gavitation explained by the theoy of infomatons Antoine Ake

2 Within the famewok of eneal elativity, GM has been disussed by a numbe of authos () It is shown that the avitational analoues to Maxwell s equations (the GM equations) an be deived fom the instein field equation Althouh GM desibes the avitational phenomena in a oet and oheent manne, it doesn t eate laity about the tue natue of the ation at a distane In the ontext of GM, the avitational field is a puely mathematial onstution that doesn t povide insiht in the mehanisms that ae at the base of the physial laws In this pape we develop the idea that, if masses an influene eah othe at a distane, they must in one way o anothe exhane data We assume that eah mass emits infomation elative to its manitude and its position, and is able to intepet the infomation emitted by its neihbous In this way we popose a physial foundation of GM by intoduin infomation as the substane of the avitational field xpliitly, we stat fom the idea that the avitational field of a mateial objet an be explained as the maosopi manifestation of the emission by that objet of mass-, eneyand anula entities ushin away with the speed of liht and ayin infomation about the position ( -infomation ) and the veloity ( -infomation ) of the emitte Beause they tanspot nothin else than infomation, we all these entities infomatons In the postulate of the emission of infomatons, we define an infomaton by its attibutes and detemine the ules that oven the emission of infomatons by a point mass that is anhoed in an inetial efeene fame The fist onsequene of that postulate is that a point mass at est - and by extension any mateial objet at est - an be onsideed as the soue of an expandin spheial loud of infomatons, that - in an abitay point - is haateised by the vetoial quantity is the density of the flow of -infomation in that point That loud of infomatons an be identified with the avitational field and the quantity with the avitational field stenth in A seond onsequene is that the infomatons emitted by a movin point mass, onstitute a avitational field that is haateised by two vetoial quantities:, the density of the -infomation flow, and B, the density of the -infomation loud We show that the elations - aisin fom the dynamis of the infomatons - between these two quantities (the laws of GM) ae the avitational analoues of the laws of Maxwell- Heaviside Next we explain the avitational inteation between masses as the eation of a point mass on the distubane of the symmety of its own avitational field by the field that, in its diet viinity, is eated and maintained by othe masses And finally we examine the emission of eney by an aeleatin mass Gavitation explained by the theoy of infomatons Antoine Ake

3 I The ostulate of the mission of Infomatons With the aim to undestand and to desibe the mehanism of the avitational inteation, we intodue a new quantity in the asenal of physial onepts: infomation We suppose that infomation is tanspoted by mass and eney less anula entities that ush thouh spae with the speed of liht () We all these infomation aies infomatons ah mateial objet ontinuously emits infomatons An infomaton always aies - infomation, that is at the oot of avitation The emission of infomatons by a point mass (m) anhoed in an inetial efeene fame O, is ovened by the postulate of the emission of infomatons: A The emission is ovened by the followin ules: The emission is unifom in all dietions of spae, and the infomatons divee with the speed of liht ( 8 m/s) alon adial tajetoies elative to the loation of the emitte dn N &, the ate at whih a point-mass emits infomatons, is time independent and dt popotional to its mass m So, thee is a onstant K so that: N & K m The onstant K is equal to the atio of the squae of the speed of liht () to the lank onstant (h): 5 K,6 k s h B We all the essential attibute of an infomaton its -spin The -spin of an infomaton efes to infomation about the position of its emitte and equals the elementay quantity of -infomation It is epesented by a vetoial quantity s, the -spin veto : s is points to the position of the emitte All -spin vetos have the same manitude, namely: s 6 6,8 m s K η 9 ( η,9 k s m with G the avitational onstant) 4 π G s, the manitude of the -spin-veto, is the elementay -infomation quantity We nelet the possible stohasti natue of the emission, that is esponsible fo noise on the quantities that haateize the avitational field So, N is the aveae emission ate Gavitation explained by the theoy of infomatons Antoine Ake

7 7 We onlude: The -field of a set of point masses at est is in any point of spae ompletely defined by the vetoial sum of the -fields aused by the distint masses Let us note that the oientation of the effetive -field has no lone a elation with the dietion in whih the passin infomatons ae movin One shows easily that the outwad -flux thouh a losed sufae in the -field of a set of anhoed point masses only depends on the spanned masses m in : Φ min ds η This elation expesses the onsevation of -infomation in the ase of a set of point masses at est The avitational field of a mass ontinuum at est We all an objet in whih the matte in a time independent manne is spead ove the oupied volume, a mass ontinuum In eah point Q of suh a ontinuum, the aumulation of mass is defined by the (mass) density ρ G To define this sala quantity one onsides a volume element dv that ontains Q, and one detemines the enlosed mass dm The aumulation of mass in the viinity of Q is defined by: dm ρ G dv A mass ontinuum - anhoed in an inetial fame - is equivalent to a set of infinitely many infinitesimal mass elements dm The ontibution of eah of them to the field stenth in an abitay point is d, the effetive field stenth in, is the esult of the inteation ove the volume of the ontinuum of all these ontibutions It is evident that the outwad -flux thouh a losed sufae S only depends on the mass enlosed by the sufae (the enlosed volume is V) ds S ρg dv η That is equivalent with (theoem of Ostoadsky) (4) : V div ρ G η Gavitation explained by the theoy of infomatons Antoine Ake
