We discuss the issues for realizing the transition via closed string tachyon condensation occurring near the horizon.

基于此，我们讨论了通过在视界附近发生闭弦快子凝聚来实现上述过程的问题。

The theoretical particles that mediate gravity, known as gravitons, may also be closed loops of string that leak off into the bulk.

理论上的粒子，例如传递引力的引力子，也可能泄漏进入主体， 形成弦的闭合回路。
