标 题: interstellar搞错了一个基本问题

地球上缺少氧气，沙尘暴，这属于行星内部矛盾，好比是天灾。其实这种级别的小灾历
史上也没少有，这种问题都解决不了，说明地球的文明还属于单行星文明。
单行星文明之上是行星际文明，此类文明可以在太阳系内纵横驰骋，改造火星，移民木
星土星的卫星不在话下。但是碰上比如太阳变成红巨星这样的灾难，行星际文明就
HANDLE不了了。
行星际文明之上是恒星级文明，此类文明穿梭于恒星之间，可以在数光年之外的另一个
恒星系建立殖民地。
而interstellsar属于单行星文明的科技水平，却想用恒星级文明的方法来解决问题，
说个不好听的话就是地下室的命操中南海的心。
1964年由苏联天文学家尼古拉·卡尔达肖夫首先提出一個文明所能夠利用的能源总量来
标度一个文明的发展程度。这就是所谓的卡尔达肖夫指数。 按照这个分类，人类连1类
文明都达不到。
Type I
"Technological level close to the level presently attained on earth,
with energy consumption at ≈4×1019 erg/sec[1] (4 × 1012 watts.) Guillermo
A. Lemarchand stated this as "A level near contemporary terrestrial
civilization with an energy capability equivalent to the solar insolation on
Earth, between 1016 and 1017 watts."[2]
Type II
"A civilization capable of harnessing the energy radiated by its own
star (for example, the stage of successful construction of a Dyson sphere),
with energy consumption at ≈4×1033 erg/sec.[1] Lemarchand stated this as "
A civilization capable of utilizing and channeling the entire radiation
output of its star. The energy utilization would then be comparable to the
luminosity of our Sun, about 4×1033 erg/sec (4×1026 watts)."[2]
Type III
"A civilization in possession of energy on the scale of its own galaxy,
with energy consumption at ≈4×1044 erg/sec."[1] Lemarchand stated this as
"A civilization with access to the power comparable to the luminosity of the
entire Milky Way galaxy, about 4×1044 erg/sec (4×1037 watts)."[2] | G*****h
