如果北極有個洞真穿南極,
5 {2 W# A& J/ p% V+ {0 j您跌入去,3 x- m2 e' j( Q% ?: G' ^
您會去到達南極~
8 R* g; x5 H& T: C6 M但到達南極後會吸回北極~~~
" X6 h, C3 D1 a1 a" J# P到北極後又會吸回南極................

事實上,地球質量是唔平衡分佈,

無乜可能，除了極熱之外，還要頂得住地心的高壓！ 未到對面你都變左屎餅啦！ 瓜！

我結論係去唔到最中心, 而喺地心同地面之間停下來. 喺個點係無地心吸力, 因地面質量對我所做成o既萬有引力, 同地心質量對我所做成o既萬有引力喺對等.

( _/ ?; b- M6 B! ?其實係去到地心,南北半球ge地心吸力先相等同抵消~so地心ga引力係0~~~~& n* w/ u6 W, }9 C* x1 c
但您之前有加速,即您本身有speed~0甘您會直去,但去南半球時又受引力,會減speed,最後係南半球表面stop~~~
