idea of rogue planets wandering the galaxy is not as far-fetched as it may sound. Gravitational tugs-of-war with other planets or passing stars can boot a planet out of its solar system.───流浪行星在星系中游走这个概念并没有它听起来那么难以捉摸，与其他星球或流星的引力之战很有可能使该星球脱离太阳系。

personal training industry as a whole was still in its infancy at this point, so this idea seemed ridiculously far-fetched, at best.───这一点上，私人培训业作为一个整体还处在起步阶段，所以这个想法充其量很是荒谬牵强。

idea that trace amounts of water in planetesimals could give rise to vast oceans may seem far-fetched until one considers how small an ocean can be relative to the size and mass of a planet.───星子中微量的水造就了宽阔的海洋这一观点也许看起来不切实际直到人们认识到相对于一颗行星的质量和体积，浩瀚的海洋是多么的渺小。
