我们通常认为月球是一个静态的、漂浮的物体，在其整个生命周期中基本上保持不变，偶尔的小行星撞击是个例外。这种理解是基于物理学的——当一颗巨大的原行星形成时，月球应该在形成后迅速冷却。
英文原文标题与摘要
Earth's Gravity May Have Kept the Early Moon's Volcanic Heart Beating
We typically think of the Moon as a static, floating object that has remained the same for basically its entire lifetime, with an occasional asteroid impact serving as an exception. That understanding is grounded in physics - the Moon should have cooled rapidly after forming when a huge protoplanet hit the early Earth around 4.5 billion years ago.
