title="Ruimtetyd">ruimtetyd</a> wat gekrom is volgens algemene relatiwiteit.</figcaption></figure> <p>Die <b>relatiwiteitsteorie</b> omvat twee teorieë deur <a href="/wiki/Albert_Einstein" title="Albert Einstein">Albert Einstein</a>: <a href="/wiki/Spesiale_relatiwiteit" title="Spesiale relatiwiteit">spesiale relatiwiteit</a> en <a href="/wiki/Algemene_relatiwiteit" title="Algemene relatiwiteit">algemene relatiwiteit</a>.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>Die belangrikste begrippe van die relatiwiteitsteorieë is: </p> <ul><li>Die grootte van lengte, massa en tyd is relatief en hang af van die posisie en bewegingsnelheid van die waarnemer.</li> <li>Die snelheid van lig is nogtans onveranderlik, dus dieselfde vir alle waarnemers.</li> <li><a href="/wiki/Ruimtetyd" title="Ruimtetyd">Ruimtetyd</a>: Ruimte en tyd moet saam en in verhouding tot mekaar beskou word.</li></ul> <p>Die begrip relatiwiteit word in die <a href="/wiki/Fisika" title="Fisika">fisika</a> veral gebruik om na enige bewegende stelsel of raamwerk met betrekking tot 'n ander bewegende stelsel te verwys. Volgens die relatiwiteitsteorie het geen liggaam 'n absolute waarde van rus of <a href="/wiki/Beweging" title="Beweging">beweging</a> nie, aangesien dit altyd relatief tot 'n ander liggaam gesien word. </p><p>Hoewel dit byvoorbeeld vir iemand lyk of 'n boom stilstaan, moet die waarnemer in gedagte hou dat sowel hy as die boom beweeg (die <a href="/wiki/Aarde" title="Aarde">aarde</a> beweeg tog met ŉ snelheid van 1800 km/h in sy baan) en dat hy relatief tot die boom bloot met dieselfde snelheid beweeg. </p><p><a href="/wiki/Galileo_Galilei" title="Galileo Galilei">Galileo Galilei</a>, 'n vroeëre natuurkundige, was in sy tyd reeds bewus van relatiwiteit en het eenvoudige wiskundige relasies geformuleer aan die hand waarvan hy 'n aantal stellings gemaak het. Albert Einstein (<a href="/wiki/1879" title="1879">1879</a> -<a href="/wiki/1955" title="1955">1955</a>) het uiteindelik sommige van Galilei se stellings weerlê. Volgens Einstein kan 'n stelsel met <a href="/wiki/Swaartekrag" title="Swaartekrag">swaartekrag</a> gesien word as 'n stelsel sonder swaartekrag wat aan ŉ versnelling onderhewig is. </p><p>Aan die hand daarvan kon hy die beweging van <a href="/wiki/Hemelliggaam" title="Hemelliggaam">hemelliggame</a> uit 'n ander oogpunt as byvoorbeeld <a href="/wiki/Newton_se_Swaartekragwet" title="Newton se Swaartekragwet">Newton</a> beskou en het hy ook die grondslag vir die moderne kosmologie gelê. Die spesiale relatiwiteitsteorie het betrekking op <a href="/wiki/Elektromagnetisme" title="Elektromagnetisme">elektromagnetisme</a>. Einstein se eerste publikasie hieroor heet.

Galileo Galilei het byvoorbeeld eenvoudige relasies opgestel aan die hand waarvan hy die volgende stellings gemaak het: </p><p>- dat die <a href="/wiki/Tyd" title="Tyd">tyd</a> in elke stelsel dieselfde is, met ander woorde dat dit oral ewe laat is (t' =1); </p><p>- dat iemand wat hom in ŉ bewegende voertuig bevind, se posisie ten opsigte van ŉ stilstaande voorwerp steeds verander, dit wil sê dat die voorwerp met 'n snelheid - v ten opsigte van die waarnemer beweeg; </p><p>- dat iemand wat in 'n voertuig (byvoorbeeld 'n trein) teen 5 km/h vorentoe loop terwyl die voertuig self teen 50 km/h beweeg, eintlik teen 55 km/h beweeg. </p><p>Sulke verskynsels was uit daaglikse ervarings bekend en tot aan die einde van die vorige eeu het niemand aan die juistheid van Galilei se stellings (Galilei-transformasies) getwyfel nie. Intussen het <a href="/wiki/James_Clerk_Maxwell" title="James Clerk Maxwell">James Clerk Maxwell</a> (<a href="/wiki/1831" title="1831">1831</a> - <a href="/wiki/1879" title="1879">1879</a>) sy teorieë in verband met elektrisiteit en elektromagnetiese golwe geformuleer en byvoorbeeld aangedui dat lig as elektromagnetiese golwe met ŉ snelheid c (c=300 000 km/s) deur ŉ lugleegte voortgeplant word. Maxwell was egter, soos vele ander, onder die indruk dat lig en ander elektromagnetiese golwe, soos radiogolwe. deur middel van ŉ medium voortgeplant word. </p><p>Die medium (<a href="/w/index.php?title=Flu%C3%AFdum&action=edit&redlink=1" class="new" title="Fluïdum (bladsy bestaan nie)">fluïdum</a>) is met 'n yl gas vergelyk wat alles omhul en "eter" genoem word. Volgens hom is ligsnelheid dan ten opsigte van die eter bepaal, en kon die snelheid van plek tot plek verskil. In 1887 het <a href="/wiki/Albert_A._Michelson" title="Albert A. Michelson">Albert Abraham Michelson</a> (<a href="/wiki/1852" title="1852">1852</a>- <a href="/wiki/1931" title="1931">1931</a>) en, onafhanklik van hom, <a href="/w/index.php?title=Edward_Williams_Morley&action=edit&redlink=1" class="new" title="Edward Williams Morley (bladsy bestaan nie)">Edward Williams Morley</a> (<a href="/wiki/1838" title="1838">1838</a> - <a href="/wiki/1923" title="1923">1923</a>) egter vasgestel dat eter die snelheid van lig nie beïnvloed nie. Hierdie negatiewe resultaat het heelwat verwarring veroorsaak en <a href="/wiki/Hendrik_Antoon_Lorentz" class="mw-redirect" title="Hendrik Antoon Lorentz">Hendrik Antoon Lorentz</a> (<a href="/wiki/1853" title="1853">1853</a> -<a href="/wiki/1928" title="1928">1928</a>) en <a href="/w/index.php?title=George_Francis_Fitzgerald&action=edit&redlink=1" class="new" title="George Francis Fitzgerald (bladsy bestaan nie)">George Francis Fitzgerald</a> (<a href="/wiki/1851" title="1851">1851</a> - <a href="/wiki/1901" title="1901">1901</a>) het onder meer geprobeer om dit aan die hand van wiskundige vergelykings te verklaar. </p><p>Albert Einstein kon egter later, aan die hand van Michelson en Morley se bevindings, die eterteorie omverwerp. Tot dusver het al die natuurkundiges steeds aangeneem dat tyd konstant is, terwyl byvoorbeeld ligsnelheid 'n veranderlike is. Michelson en Morley het egter ook vasgestel dat, afgesien van die resultate ten opsigte van eter, die ligsnelheid altyd dieselfde was. Hulle het byvoorbeeld eers die snelheid van lig teen die aarde se beweging, en toe saam met die aarde se beweging bepaal, en elke keer dieselfde resultaat verkry, naamlik 300 000 km/s. </p><p>Einstein het toe besef dat ligsnelheid, en nie tyd nie, 'n konstante is. Die snelheid van lig, relatief tot ŉ waarnemer, is dus konstant, ongeag die snelheid waarteen hy self beweeg. Die veranderlikheid van tyd kan geïllustreer word aan die hand van die begrip gelyktydigheid. </p><p>Veronderstel dat 2 horlosies, byvoorbeeld 1 000 km van mekaar af, gelyk gestel moet word. Van die een horlosie af moet 'n sein dus op 'n gegewe oomblik gestuur word om die moment te bepaal waarop die ander horlosie reggestel moet word. Die vinnigste bekende manier waarop 'n sein gestuur kan word, is met behulp van lig (300 000 km/s). Selfs lig, wat teen hierdie ontsaglike hoë snelheid beweeg, sal egter ŉ tydjie neem om 1 000 km te oorbrug. </p><p>Die tweede horlosie sal dus altyd ŉ sekere tyd agter die eerste een wees. Tyd het dus geen absolute waarde nie aangesien dit van plek tot plek kan verskil. Oor klein afstande is tydsverskille baie klein, amper weglaatbaar, maar oor groot afstande is die tydsverskil opmerklik. </p><p>'n Ster wat 1 000 ligjare van die aarde verwyder is, se lig neem 1 000 jaar om die aarde te bereik. Op enige gegewe oomblik is daar dus 'n tydsverskil van 1 000 jaar tussen die aarde en die <a href="/wiki/Ster" title="Ster">ster</a> en is dit onmoontlik om iets wat op die 2 liggame gelyktydig gebeur, waar te neem. </p> <div class="mw-heading mw-heading2"><h2 id="Twee_teorieë"><span id="Twee_teorie.C3.AB"></span>Twee teorieë</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Relatiwiteitsteorie&veaction=edit&section=2" title="Wysig afdeling: Twee teorieë" class="mw-editsection-visualeditor"><span>wysig</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Relatiwiteitsteorie&action=edit&section=2" title="Edit section's source code: Twee teorieë"><span>wysig bron</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Die relatiwiteitsteorie het meer as ’n enkele nuwe fisikateorie verteenwoordig.

Die tweede veronderstelling was (in Einstein se tyd) ’n heel nuwe beginsel, met besonder verreikende gevolge ondanks die eenvoud daarvan. Om dié twee basisidees met mekaar te versoen, is spesiale transformasies, die sogenaamde <a href="/w/index.php?title=Lorentz-transformasie&action=edit&redlink=1" class="new" title="Lorentz-transformasie (bladsy bestaan nie)">Lorentz-transformasies</a>, nodig om plek en tyd van die een waarnemer om te reken in plek en tyd van die ander.
