摘　　要：提出了澳大利亚是地球上一颗陨落的卫星的假说。 ６ ７００万年前，地球曾吸引它自己的一颗卫星，撞击在东非－马达加斯加附近，这颗卫星就是澳大利亚．澳大利亚在地表上的下陷过程中不断东移，造成它北面和东面半圆形的弧形构造。由于撞击作用，使太平洋洋底的部分岩体飞升到天上，成为我们头上的这轮月亮。新月亮在飞升时，把太平洋北面和西面拖曳成花彩般的弧形构造，并把美洲西部推覆成科边勒拉（落矶山）山脉和安第斯山脉。About 67 million years ago the Earth presumably attracted its satellite to collide with the areas near Madagascar--East Africa. This satellite is just present Australia. The gradual eastward movement of Australia during the surface subsidence could have resulted in the semi-circular arc structure in its northern and eastern parts. At the same time the collision might have caused part of the rock mass at the bottom of the Pacific Ocean to rise to the sky and formed the Moon above us. Consequently the rise of the New Moon pulled the northern and western Pacific to form laced arc structures and ushed western America to form the Cordilleras (Rocky Mountains) and the Andes Mountains.
