title="Gravidade">gravidade</a> na maioría dos sistemas teóricos de gravidade <a href="/wiki/Teor%C3%ADa_cu%C3%A1ntica" title="Teoría cuántica">cuántica</a>. As principais características que debería ter: ser sempre atractivo (a gravidade endexamais repele), ter efecto sen importar a distancia entre os corpos, e ademais habería unha cantidade ilimitada deles. Na <a href="/wiki/Teor%C3%ADa_cu%C3%A1ntica" title="Teoría cuántica">teoría cuántica</a>, isto define un <a href="/wiki/Bos%C3%B3n" title="Bosón">bosón</a> de <a href="/wiki/Spin" title="Spin">spin</a> par (2 neste caso) cunha <a href="/wiki/Masa" title="Masa">masa</a> en repouso de valor cero. </p><p>Postúlase a existencia dos gravitóns debido ao éxito da teoría cuántica noutras áreas. Por exemplo, a <a href="/wiki/Electrodin%C3%A1mica" class="mw-redirect" title="Electrodinámica">electrodinámica</a> pódese explicar moi ben aplicándoselle a cuantificación ós <a href="/wiki/Fot%C3%B3n" title="Fotón">fotóns</a>. Neste caso, suponse que os fotóns son creados (e destruídos) continuamente por tódalas partículas con <a href="/wiki/Carga_el%C3%A9ctrica" title="Carga eléctrica">carga eléctrica</a>, de xeito que as interaccións entre estes fotóns xeran as forzas macroscópicas ás que estamos afeitos, coma o <a href="/wiki/Magnetismo" title="Magnetismo">magnetismo</a>. </p><p>Considerando o amplo éxito da teoría cuántica ao describi-la maioría das forzas básicas do <a href="/wiki/Universo" title="Universo">universo</a>, semella axeitado asumir que os mesmos métodos haberán de servir para explica-la gravidade. Fixéronse moitas tentativas de introducir o ata o de agora invisible gravitón, que funcionaría máis ou menos coma o fotón. Isto levaría a unha teoría cuántica gravitatoria, aínda que o <a href="/w/index.php?title=Corpo_matem%C3%A1tico&action=edit&redlink=1" class="new" title="Corpo matemático (a páxina aínda non existe)">corpo matemático</a> sería máis complexo. </p><p>Unha teoría como a descrita precisaría que o gravitón operase de xeito semellante ao fotón; mais, ao contrario que na <i>electrodinámica</i>, onde os fotóns interactúan directamente entre eles e as partículas con carga, a gravidade no traballa de xeito tan sinxelo. Os feitos experimentais mostran que a gravidade créase por calquera forma de <a href="/wiki/Enerx%C3%ADa" title="Enerxía">enerxía</a> (e a <a href="/wiki/Masa" title="Masa">masa</a> é unicamente unha forma condensada de enerxía, segundo a célebre ecuación de <a href="/wiki/Einstein" class="mw-redirect" title="Einstein">Einstein</a>), o cal é difícil de describir nuns termos semellantes á carga eléctrica. Ata o de agora tódalas tentativas de crear unha teoría cuántica sinxela da gravidade fracasaron. </p><p>A detección do gravitón, se é que existe, é unha tarefa bastante problemática. Estas partículas portarían moi pouca enerxía, polo tanto a detección sería moi difícil. A única maneira de detectalss sería buscar os casos nos que o movemento ou a enerxía dun corpo mudase nunha forma distinta da prevista pola <a href="/wiki/Relatividade_Xeral" class="mw-redirect" title="Relatividade Xeral">Teoría Xeral da Relatividade</a>, pero un dos principios básicos da gravidade cuántica sería que deberían coincidir en maior un menor medida con estas predicións relativistas. </p> <table style="clear:both;
