Relativitat

Ia theorias os relativitat sigwrnt od existent equivalent referentials kay describe ia phenomens, ia meges relative uni referential se deducend, sekwent sem transformations, ex ia sama meges relative alyi referential, ed ia physic loys, expremend ia sibias inter ta meges, remanend non-variant. 
 Is observer ep id trehcend navo vidt id durbino muken kata atopp ids mast nifalle seid. Is observer ep id ripa vidt id durbin kwehre un vrongh itner, ed gwahe perodh sammel quem id nav. Bo observers vident id durbin hihes id deck pod id mast. Id horizontal inkapemsyrat est different sekwent iens dwo observers. (Id nav est diken fanzowe petis oku kay kyunggiawe id effect)
==Id inertial relativitatsdastur==
Relativitat est prabh-ye assocyen ad Einstein, yed est id nam Galileo quod tehbiet preter bihe unien in physique ei lexis relativitat. Seighi id coppernican hypothese od Terra revolvt ed tournt, con alter planetes, ambh Sowel eet mathematic-ye satisfacend, id kwecto stus protie vyigic physic arguments : neid effect os ids eventual rotation ghehdt bihe experimental-ye verifien ep Terra ar, kam Galileo dik, hol jinkdout ep Terra kamsei id esiet still. Id sam ghehldt ep un trehcend nav : hatta ye hog syrat, tando tod syrat est uniforme, ghehdt bihe lict ball ep id decko kamsei id nav esiet still; ghehdt bihe mucto kata atopp id mast un xeudil, id nifallsiet pod id mast. Yed, un "still" observer, quel vidt pon id ripa id navo fanzowe ye hog syrat, comvidsiet id xeudil falle pod id mast, lakin id nifallsiet pro el quer id nav hat wohght id, lyt-ye dalger quem id inkapemstet quer id habiet nifallen sei id vecel habiet remanen still. El observer quel wehst in id perodhfanzownd vecel ed tel still ep id ripa ne vide id sam ject : pro uter, id xeudil fallt vertical-ye, pro alter, id fallt sekwent un certain inclination ed bo mayne prabh : ia (mathematic) wirts ios observation different sekwent id respective stand al observer, yani sekwent id chust referential. Talg est id inertial relativitatsdastur. Smad precide od est neid still referential in id absolut, in id universe - quo collabihsit id aristoteliste cosmologia quod placit in id centre id still Terra. Sont tik movend corpsa, ye relative syrats binisbat mutu.
Ep levter kwiter sont dwo trehcend woghs : id gehlb auto wehght ye 140 km/h binisbat id strad, id blou auto ye 120 km/h. Id syrat ios gehlb auto binisbat id blou auto est yinjier 140-120 = 20 km/h. Ep dexter kwiter est id blou auto still, menxu id rudh "superauto" trehct nun ye 5000 km/s syrat. Id syrat iom bams iom phars ios blou auto binisbat id rudh auto est semper 299 795 km/s (syrat os luce) ed ne 299 795 - 5000 km/s, todghi syrat est un constance in quodkwe referential.
==Einstein ed id relativitat os waktmeid==
Einstein hat extenden id inertial relativitatsdastur hin encause idpet dayi uns absolut rewos eni-yod ia corpsa trehcient, ye relative syrats, hissapt sekwent un d/w sibia ( d = andhto distance ed w = wakt), quer w prehpt natural-ye ka un constance. In-kap, lit de ghabihes un paradox. Prabhil-ye, id syrat uns corpos B, quod trehct eni uno movend referential A, addeiht sien syrato tei ios referential : sei trehco ye 5 km/h in un train wehghend ye 150 km/h, mien syrat sessiet 155 km/h pro un extos observer. Idghi experimento deict od ye hoger id syrat uns trehcend corpos ed ye proscher id est id syrat os luce, ye minter se addeihnt ia syrats. Id syrat os luce est in druve borswent ed constant. Khact ses sem corpos meis oku quem luce. Id luce os un star quod swehbht baygh dalg ud un observer ep Terra hat tohrpt sem wakto kay ghehde al. Estghi neid faurankweit os luce in un rewos quod skeipiet semo neutral ambghehrdend milieu quod videihiet observers, pon quodkwe stand, id sam starwent waurn... Api, ad to adduxit id newtonskum conception quod kwehct natural, om absolut rewos ed wakt identic pro quants. In druve, un star wehst ye sem wakt ed sem distance ud different observers qui, ob id inertial relativitatsdastur, ne vide ia sam jects sekwent id referential sont-yei bohnden. Lakin, changent ne tik ia meids iom rewosdistancen sekwent ia stands qualkwe, sontern idschi waktmeid. Mathalan, ia informations ex dwo surces os luce equidistant ud un observer wehsend in un bestohmt referential ghehdsient al sammel; nient ghehde sammel uni observer wehsend in un different referential. Wakto ghi skeipt un variable kam longe, wure ed dube, quom meids changent sekwent ia respective stands in rewos ed wakt im observers (iom referentials), movend binisbat mutu. Punor, id syrat os luce est un constance.
 Bo observers meide pro id syrat os luce id sam wirt, quayque el levter trehct.
==General relativitat==
Id theoria os einsteinsk relativitat permiss concilye id experiment ios borswent syrat os luce con id inertial relativitatsdastur, ed sammel resolvit tod paradox ios impossibilitat os addihes mecanic-ye syrats. Contribuit un revolution in nies weidos os fiker rewos ed wakt, chunke ia saats varyeer sekwent ia referentials... kay prehpihes alya paradoxa : sei ghehdiemos trehce ye un syrat prokwem tod os luce, noster saat esiet maung lenter; ed sei reikiemos Terra, habiems remanto maung yuner quem ti ud qui habiems fortrohct samat. Yed importet mehme od rewos ed wakt ne skeipe aundifference milieus, ni formes semkam indifferent dia ir mathmouns. Einstein isnaht nos ad bemehne ia ka habend uno materialitat, au bariem ka habend bestohmen physic suedsa. 
Generalisend-ye id dastur os special relativitat ei fall iom acceleret systemes, Einstein hat formulet id equivalence principe : id egalitat iom gwaurod massen ed iom inert massen hat ka consequence od est impossible enderkwites, in un clus ed begrancet rewos, ia effects uns gravitationscamp ud ta iom inertiaforcen resultend ex acceleret movs. General relativitat it tyeict id synthese om mecanique ed gravitation. Id gravitationsinteraction est describen ka un kehmb om rewos ed wakt induct ab id presence om masses, ia particules andhend ia curves om minimala "longes" tos ne-euclidei kehmb rewoswakt, wa Minkowski rewos. 
Id theoria os general relativitat, ex quod gwehme ia models os moderne cosmologia ed id theoria ios big bang, buit confirmet ab mult astronomic observations (perodhia os Mercurs perihelium, kehmb ios agmios iom gwayderbams prosch uno massive corpos kam Sowel) ed nuntro hat kamyapt neid experimental testo defaule tod theoria. Also, in 2016, ia gravitational wands previden ab general relativitato takriban oin secule prever ghohd bad bihe detegen ab id LIGO instrument in ia Uniet Stats os America
