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！

' F2 O5 W# V' T5 r都話明"假設"ar!!!!!!假設唔一定要正確ga.............

' A7 E3 k" A& G" l3 B- [) Y8 }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.

$ m7 K+ \7 m* v6 P9 O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+ g/ `7 q2 G0 x0 ]% t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~~~
