  • comparison, a planet the size of Jupiter would only obscure the star by just 1%.

    相比之下,一顆木星大小的行星只會將恆星遮擋1%。

  • It's possible that eventually we'll need more energy than what we can produce on earth, so, the logical end step for maximum energy

    有可能最終我們需要的能量會超過我們在地球上所能生產的能量,所以,為了最大限度地利用能量,合乎邏輯的最終步驟是:

  • harvesting is to harvest it directly from the Sun from one of three different types of Dyson spheres.
