O QUE SIGNIFICA EVENT HORIZON EM INGLÊS
Horizonte de eventos
Um horizonte de eventos é, na relatividade geral, um limite no espaço-espaço além do qual os eventos não podem afetar um observador externo. Em termos leigos, é definido como "o ponto de não retorno", ou seja, o ponto em que a atração gravitacional torna-se tão grande que impossibilita a fuga. O caso mais comum de um horizonte de eventos é o que circunda um buraco negro. A luz emitida além do horizonte do evento nunca pode chegar ao observador externo. Da mesma forma, qualquer objeto que se aproxima do horizonte do lado do observador parece diminuir a velocidade e nunca passar completamente pelo horizonte, com sua imagem cada vez mais redshifted com o passar do tempo. O objeto de viagem, no entanto, não experimenta efeitos estranhos e, de fato, passa pelo horizonte em uma quantidade finita de tempo apropriado. Os tipos de horizonte mais específicos incluem os horizontes absolutos e aparentes relacionados mas distintos encontrados em torno de um buraco negro. Outras noções distintas incluem o horizonte Cauchy e Killing; as esferas de fotões e as ergospheres da solução Kerr; horizontes de partículas e cosmológicos relevantes para a cosmologia; e horizontes isolados e dinâmicos importantes na pesquisa atual do buraco negro.
definição de event horizon no dicionário inglês
A definição de horizonte de eventos no dicionário é a superfície em torno de um buraco negro que encerra o espaço do qual a radiação eletromagnética não pode escapar devido à atração gravitacional. Para um buraco negro não rotativo, o raio é proporcional à massa do buraco negro.
