En möjlig definition för oändlighet (men inte den enda) ges med hjälp av <a href="/wiki/Kardinalitet" title="Kardinalitet">kardinalitet</a> – där man säger att två <a href="/wiki/M%C3%A4ngd" title="Mängd">mängder</a> är lika stora om man kan para ihop <i>varje</i> element i den ena mängden med ett (och endast ett) element i den andra mängden, och vice versa. Har du tre tärningar och tre femtioöringar är de lika många, eftersom de kan paras ihop ett och ett. </p><p>Matematikern <a href="/wiki/Richard_Dedekind" title="Richard Dedekind">Richard Dedekind</a> gav en definition av oändlighet som bygger på att en mängd är oändlig om man kan ta bort minst ett element från mängden, och den fortfarande är lika stor (det vill säga har samma kardinalitet). Det kan matematiskt uttryckas på följande vis: <i>En mängd A är oändlig om det finns en mängd </i><b>B</b> ⊂ <b>A</b><i> sådan att </i><b>A</b><i> och </i><b>B</b><i> har samma kardinalitet.</i> Ett exempel på detta är de naturliga talen <span style="white-space:nowrap">ℕ = {0, 1, 2, 3, …</span>} och de jämna (icke-negativa) talen <span style="white-space:nowrap"><b>B</b> = {0, 2, 4, 6, 8, …</span>}. Eftersom man kan para ihop <i>varje</i> element i <b>B</b> med ett naturligt tal (exempelvis genom att dela med två) har de samma kardinalitet som ℕ själv – de är lika många (enligt detta sätt att mäta). </p><p>Ett exempel på detta är paradoxen <a href="/wiki/Hilberts_hotell" title="Hilberts hotell">Hilberts hotell</a>. </p> <div class="mw-heading mw-heading2"><h2 id="Olika_stora_oändligheter"><span id="Olika_stora_o.C3.A4ndligheter"></span>Olika stora oändligheter</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=O%C3%A4ndlighet&veaction=edit&section=2" title="Redigera avsnitt: Olika stora oändligheter" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=O%C3%A4ndlighet&action=edit&section=2" title="Redigera avsnitts källkod: Olika stora oändligheter"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/Fil:Radionella_tal.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/d9/Radionella_tal.png/250px-Radionella_tal.png" decoding="async" width="250" height="200" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/d9/Radionella_tal.png/375px-Radionella_tal.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/d9/Radionella_tal.png/500px-Radionella_tal.png 2x" data-file-width="799" data-file-height="638" /></a><figcaption>En av flera möjliga sätt att räkna upp de <a href="/wiki/Rationella_tal" title="Rationella tal">rationella talen</a>.</figcaption></figure> <p><a href="/wiki/Naturliga_tal" title="Naturliga tal">De naturliga talen</a>, och alla mängder som är lika stora som dessa kallas för <a href="/wiki/Uppr%C3%A4knelig" class="mw-redirect" title="Uppräknelig"><i>uppräkneliga</i></a> – det går att börja att räkna vid ett element (exempelvis 0) och om man räknar på ett bra vis kommer man förr eller senare fram till vilket element som helst i mängden (exempelvis 10<sup>1000</sup>+1). Räknar man däremot på ett dåligt vis – exempelvis bara alla jämna tal – kan man räkna oändligt länge utan att få med ens 1. Något överraskande är det att även de rationella talen – alla möjliga bråktal – är uppräkneliga. Trots att de till skillnad från de naturliga talen är en <a href="/wiki/T%C3%A4t_m%C3%A4ngd" title="Tät mängd">tät mängd</a> – varje intervall på tallinjen innehåller oändligt många rationella tal – är de alltså inte fler än de betydligt glesare naturliga talen. Detta kan uppfattas som icke-intuitivt, men det man måste fråga sig är <i>hur man bedömer oändligheter</i>. Om man använder kardinalitet är frågan om även de rationella talen går att räkna upp i en ordning, vilket faktiskt går (se bild). </p><p>Däremot visar sig de <a href="/wiki/Reella_tal" title="Reella tal">reella talen</a> <i>inte</i> vara uppräkneliga. De är alltså i denna mening <i>fler</i> än de naturliga talen, och slutsatsen blir alltså att det finns större och mindre oändligheter. </p> <div class="mw-heading mw-heading2"><h2 id="Potentiell_oändlighet"><span id="Potentiell_o.C3.A4ndlighet"></span>Potentiell oändlighet</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=O%C3%A4ndlighet&veaction=edit&section=3" title="Redigera avsnitt: Potentiell oändlighet" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=O%C3%A4ndlighet&action=edit&section=3" title="Redigera avsnitts källkod: Potentiell oändlighet"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><i>Potentiell oändlighet</i> används för att hänvisa till processer som i princip kan fortsätta för evigt, eller till objekt som i princip kan förstoras för alltid.

Möjligheten till detta har varit föremål för mycket debatt.

Han fortsatte dock och insåg att oändliga mängder till och med kan ha olika storlekar, skiljde mellan <a href="/wiki/Uppr%C3%A4kneligt_o%C3%A4ndlig" class="mw-redirect" title="Uppräkneligt oändlig">uppräkneligt oändliga</a> och <a href="/wiki/Ouppr%C3%A4knelig" class="mw-redirect" title="Ouppräknelig">ouppräkneliga</a> mängder, och utvecklade sin teori om <a href="/wiki/Kardinaltal" title="Kardinaltal">kardinaltal</a> baserad på observationen. Hans uppfattning rönte så småningom framgång och modern matematik accepterar faktisk oändlighet. Vissa utökade <a href="/wiki/Tal" title="Tal">talsystem</a>, som till exempel <a href="/wiki/Surreella_tal" title="Surreella tal">surrealistiska tal</a>, omfattar de vanliga (ändliga) talen och oändliga tal av olika storlekar. </p> <div class="mw-heading mw-heading2"><h2 id="Frågor_kring_oändlighet"><span id="Fr.C3.A5gor_kring_o.C3.A4ndlighet"></span>Frågor kring oändlighet</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=O%C3%A4ndlighet&veaction=edit&section=5" title="Redigera avsnitt: Frågor kring oändlighet" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=O%C3%A4ndlighet&action=edit&section=5" title="Redigera avsnitts källkod: Frågor kring oändlighet"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>En fråga är huruvida faktisk oändlighet finns i vårt <a href="/wiki/Universum" title="Universum">universum</a>, om det finns oändligt många stjärnor, om universum har oändlig volym och utsträcker sig i det oändliga och så vidare. Detta är en viktig öppen fråga för <a href="/wiki/Kosmologi" title="Kosmologi">kosmologin</a>. Det bör noteras att frågan om att vara oändlig är logiskt skild från frågan om att vara begränsad. Den tvådimensionella jordytan är exempelvis ändlig, men har ändå ingen ände. Genom att färdas rakt långt nog, så återkommer man i princip till startpunkten. I princip kan universum vara sådant på motsvarande sätt; om man flyger med rymdskepp rakt fram tillräckligt länge, kanske man slutligen återkommer till startpunkten, dock visar alla nuvarande observationer på att universum är "platt" och inte "krökt" och att man därmed aldrig kommer att komma runt universum så att man hamnar på samma plats igen. Detta kan dock bero på att krökningen är så avskalad att man inte kan observera den ens med ljusårs avstånd. </p><p>En annan fråga är om det matematiska begreppet oändlighet har någon koppling till det religiösa begreppet <a href="/wiki/Gud" title="Gud">gud</a>.
