距離地球最近的黑洞，比太陽大7倍，正以快4倍的速度向地球飛來
黑洞是一種引力強大的天體，所過之處無所不吸，就連光都跑不了，這種東西數量很少嗎？不是的！天文學家們通過天文觀測預估僅僅在銀河系中就至少有200萬個黑洞，而且這種東西神出鬼沒，我們并不容易發現它的影子，只能通過它對周圍物質的擾動來判斷它的存在，而如果它處于荒涼的星際空間，周圍沒有較多物質的話，人類現在的技術是無法觀測到它的存在的。
那么太陽系附近有黑洞嗎？目前人類還沒有發現，如果真有黑洞過來的話，那么它很快就會摧毀整太陽系，把八大行星及其它天體吞入腹中，最后甚至連太陽也吞下去，從而把整個太陽系都掃蕩干凈。
那么太陽系不會遇到這樣的黑洞嗎？這個誰也不敢打包票，15年前法國天文學家曾經宣布，有一個正在快速飛行的黑洞，前進的方向正是地球，這個黑洞已被命名為"GRO J1655-40"，距離地球有6000光年，法國天文學家認為它是一個黑洞，并且形成時間較早，質量已達太陽的7倍。
