Existe uma equa\u00e7\u00e3o que determina o raio para o qual uma massa deve estar totalmente concentrada para que o sistema se transforme num grande buraco negro.\u00a0<\/p>\n

Esta equa\u00e7\u00e3o \u00e9 conhecida como Raio de Schwarzschild e \u00e9 escrita da seguinte forma:
\nRs = 2Gm<\/u>
\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 C ao quadrado <\/p>\n

Onde:\u00a0
\n
\nRs<\/strong> \u00e9 o raio de Schwarzschild
\nG<\/strong> \u00e9 a constante gravitacional , que \u00e9 (6,67 x 10 elevado a \u00a0-11 Nm2\/kg2)
\nM<\/strong> \u00e9 a massa do objeto e
\nC2<\/strong> \u00e9 a velocidade da luz ao quadrado, ou seja (898755 x 10 elevado a 16 m2\/s2)\u00a0<\/p>\n

Sendo assim, se uma pessoa possui uma massa de 70 kg voc\u00ea teria que compact\u00e1-la num raio de: 3,5.10 elevado a \u00a0-24 m\u00a0<\/p>\n

Ou seja, infinitesimalmente menor que as dimens\u00f5es de um \u00e1tomo.\u00a0<\/p>\n

F\u00e1cil, n\u00e3o? <\/p>\n
