Maak nu de plaat nat; het blok zal een grotere weg afleggen, alvorens tot stilstand te komen. Neem dan een blok droogijs (bevroren koolstofdioxide). Dit glijdt bijzonder soepel over een luchtkussen van koolstofdioxidedamp. Neem dan waar dat dit blok veel verder gaat glijden, en wel zonder een noemenswaardige vermindering van snelheid nu. Voorafgaand aan Galileo Galileï (1564 - 1642) was algemeen de gedachte dat er altijd een kracht nodig is om een object met constante snelheid te laten bewegen. Galileï zag in dat het juist de wrijvingskrachten zijn die een vertraging veroorzaken. Wanneer de wrijving minder wordt, dan is er ook minder afname van snelheid. Hij beredeneerde dat als het zou lukken om alle krachten van een object te verwijderen, inclusief de wrijvingskrachten, dat dan de snelheid van een lichaam zelfs nooit zal veranderen. Deze eigenschap noemde hij <a href="/wiki/Traagheid" title="Traagheid">'inertia'</a>.</dd></dl> <dl><dd>Dit brengt met zich mee dat er mechanisch geen verschil bestaat tussen een object in rust of een object dat met constante snelheid beweegt.</dd></dl> <dl><dd>Stel u voor dat u een reiziger bent in een trein, die met constante snelheid horizontaal langs een rechte lijn beweegt. U plaatst een knikker in het gangpad. Relatief ten opzichte van de trein is de knikker in rust, zolang de trein met constante snelheid ten opzichte van de rails beweegt. Relatief ten opzichte van de rails beweegt deze met dezelfde snelheid als de trein. Zowel de trein, zolang die met constante snelheid beweegt, als de rails zijn nu, in goede benadering, inertiaal systemen. <dl><dd>(Wanneer de machinist begint af te remmen voor het volgende station, dan vertraagt de trein ten opzichte van het perron - een negatieve versnelling is dit - en u zult zien dat de knikker naar voren begint te rollen. Die is ineens aan het versnellen ten opzichte van de trein, ondanks het feit dat er geen kracht op aan het inwerken is! Nu vormt de trein een referentiesysteem dat versnelt ten opzichte van een inertiaal referentiesysteem en is deze dus geen inertiaal referentiesysteem meer.)<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></dd></dl></dd></dl> <div class="mw-heading mw-heading2"><h2 id="Speciale_relativiteitstheorie">Speciale relativiteitstheorie</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Relativiteitstheorie&veaction=edit&section=3" title="Bewerk dit kopje: Speciale relativiteitstheorie" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Relativiteitstheorie&action=edit&section=3" title="De broncode bewerken van de sectie: Speciale relativiteitstheorie"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="hatnote" style="margin-bottom:0.5em; padding:0.5em 0 0.5em 1.6em; font-size:95%;" role="note"><span typeof="mw:File"><span><img alt="" src="//upload.wikimedia.org/wikipedia/commons/thumb/e/ee/1rightarrow_blue.svg/15px-1rightarrow_blue.svg.png" decoding="async" width="15" height="15" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/e/ee/1rightarrow_blue.svg/23px-1rightarrow_blue.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/e/ee/1rightarrow_blue.svg/30px-1rightarrow_blue.svg.png 2x" data-file-width="480" data-file-height="480" /></span></span> <i>Zie <a href="/wiki/Speciale_relativiteitstheorie" title="Speciale relativiteitstheorie">Speciale relativiteitstheorie</a> voor het hoofdartikel over dit onderwerp.</i></div> <p>De speciale relativiteitstheorie werd in <a href="/wiki/1905" title="1905">1905</a> ontwikkeld door Albert Einstein.<sup id="cite_ref-Publicatie_2-0" class="reference"><a href="#cite_note-Publicatie-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Deze theorie gaat uit van de volgende twee <a href="/wiki/Axioma" title="Axioma">postulaten</a>: </p> <ul><li>De wetten van de <a href="/wiki/Natuurkunde" title="Natuurkunde">natuurkunde</a>, inclusief die van de <a href="/wiki/Elektrodynamica" title="Elektrodynamica">elektrodynamica</a>, zijn dezelfde voor waarnemers in <a href="/wiki/Inertiaalstelsel" title="Inertiaalstelsel">inertiaalstelsels</a> die <a href="/wiki/Eenparig" class="mw-redirect" title="Eenparig">eenparig</a> ten opzichte van elkaar bewegen.</li> <li>De <a href="/wiki/Lichtsnelheid" title="Lichtsnelheid">lichtsnelheid</a> in <a href="/wiki/Vacu%C3%BCm" title="Vacuüm">vacuüm</a> is een universele constante, oftewel: waarnemers in inertiaalstelsels meten voor de lichtsnelheid in vacuüm altijd dezelfde snelheid (later vastgesteld op 299.792.458 m/s), onafhankelijk van hun onderlinge, relatieve beweging.</li></ul> <p>Het eerste postulaat leunt in feite dicht aan bij het basisidee van de relativiteitstheorie van Galilei. Het tweede postulaat was (ten tijde van Einstein) een geheel nieuw principe, met (ondanks zijn formele eenvoud) bijzonder verreikende gevolgen. Om deze twee basisideeën met elkaar te verzoenen, zijn er speciale transformaties, de <a href="/wiki/Lorentztransformatie" title="Lorentztransformatie">lorentztransformaties</a>, nodig om plaats en tijd van de ene waarnemer om te rekenen in de plaats en tijd van de andere. Hieruit volgt dat plaats en tijd met elkaar zijn verbonden. Evenzo zijn <a href="/wiki/Elektrisch_veld" title="Elektrisch veld">elektrische</a> en <a href="/wiki/Magnetisch_veld" title="Magnetisch veld">magnetische velden</a> <b>E</b> en <b>B</b> voor verschillende waarnemers met lorentztransformaties in elkaar om te rekenen. </p><p>Het artikel van Einstein verscheen in 1905 onder de titel <i>Zur Elektrodynamik bewegter Körper</i>, over de elektrodynamica van bewegende lichamen. De theorie heeft als postulaat (veronderstelling, aanname) dat de lichtsnelheid in vacuüm hetzelfde is voor alle waarnemers. Het postulaat heeft geen relatie met de resultaten van het <a href="/wiki/Michelson-Morley-experiment" title="Michelson-Morley-experiment">experiment van Michelson en Morley</a>, waar de wetenschap tot op dat moment ook niet goed raad mee wist. In deze experimenten was aangetoond dat er geen absoluut stilstaand medium, de <a href="/wiki/Ether_(medium)" title="Ether (medium)">ether</a>, bestaat, dat als drager van lichtgolven zou fungeren. Dat licht geen drager nodig heeft, werd begrijpelijk toen aangetoond was dat licht ook gezien kan worden als bestaande uit deeltjes (fotonen). </p><p>De speciale relativiteitstheorie is ook volledig in overeenstemming met de <a href="/wiki/Wetten_van_Maxwell" title="Wetten van Maxwell">wetten van Maxwell</a> voor het <a href="/wiki/Elektromagnetisme" title="Elektromagnetisme">elektromagnetisme</a>. <a href="/wiki/Magnetisme" title="Magnetisme">Magnetisme</a> is het relativistische effect van <a href="/wiki/Elektriciteit" title="Elektriciteit">elektriciteit</a>. Stel dat een waarnemer een stilstaande elektrische lading ziet en dus een elektrisch veld. Een andere waarnemer in eenparige beweging ten opzichte van de eerste ziet dan een bewegende lading, dus een elektrische stroom, dus een magnetisch veld. </p><p>Uit de speciale relativiteit volgt ook Einsteins beroemde <a href="/wiki/Massa-energierelatie" title="Massa-energierelatie">massa-energierelatie</a> <span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle \mathbf {E} =\mathbf {mc^{2}} }"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mrow class="MJX-TeXAtom-ORD"> <mi mathvariant="bold">E</mi> </mrow> <mo>=</mo> <mrow class="MJX-TeXAtom-ORD"> <mi mathvariant="bold">m</mi> <msup> <mi mathvariant="bold">c</mi> <mrow class="MJX-TeXAtom-ORD"> <mn mathvariant="bold">2</mn> </mrow> </msup> </mrow> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle \mathbf {E} =\mathbf {mc^{2}} }</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/2f7ca8d6a1870e55071428c0ea4208cbc97a27a8" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.338ex; width:9.447ex; height:2.676ex;" alt="{\displaystyle \mathbf {E} =\mathbf {mc^{2}} }"></span>, die de gelijkwaardigheid van <a href="/wiki/Massa_(natuurkunde)" title="Massa (natuurkunde)">massa</a> en <a href="/wiki/Energie" title="Energie">energie</a> uitdrukt.

Volgens Newton is de zwaartekracht sneller dan het licht. Als bijvoorbeeld de <a href="/wiki/Maan" title="Maan">maan</a> opeens zou verdwijnen, zou je eerst zien dat de getijden zich terugtrokken en één seconde later pas dat de maanschijf van de hemel verdween. In de algemene relativiteitstheorie doet ook het effect van de zwaartekracht zich niet sneller dan het licht gelden. </p><p>Einstein voorspelde zo de afbuiging van licht van een ster door de zon. <a href="/wiki/Arthur_Eddington" title="Arthur Eddington">Arthur Eddington</a> nam dit waar bij de <a href="/wiki/Zonsverduistering" title="Zonsverduistering">zonsverduistering</a> op het eiland <a href="/wiki/Principe_(eiland)" title="Principe (eiland)">Principe</a> op 29 mei 1919.
