Elon Musk’s plans for the future of SpaceX, and humanity, are rooted in an idea conceived in the 1960s when astronomers began to pick up mysterious, unknown radio sources in the cosmos.Soviet astronomer Nikolai Kardashev was a pioneer in the search for extraterrestrial intelligence at the time, and some of the signals fascinated him. Intrigued by the idea that a transmission from potential alien civilizations could possibly be detected from Earth, he proposed a scale to classify such civilizations based on the energy they could produce — and then devote to interstellar communications. His concept is now known as theKardashev scale.Musk hasreferencedthe scale often, most recently in video shared on X, his social platform, ahead of SpaceX’s blockbuster initial public offering in June and in asigned statementon the company’s website, which summarizes arequestfiled this year with the US Federal Communications Commission.In the request, SpaceX asks for permission to send up to 1 million new satellites into orbit, with the goal of creating data centers in space. Musk said that this new constellation of satellites would represent “a first step towards becoming a Kardashev II-level civilization.”Elon Musk has directly referenced the Kardashev scale in relation to his future plans for SpaceX.Josh Edelson/Getty ImagesThe Kardashev scale has three levels, moving from planet to star to galaxy. A Type I civilization can use all the energy of a single planet, either produced by the planet itself — for example in the form of geothermal or wind power — or received from its host star, like solar power. A Type II civilization can use the entire energy output of a star, as well as send information across galactic distances. A Type III civilization can harness the power of a whole galaxy and send information across multiple galaxies.The Kardashev scale has its detractors, but it has been a catalyst for discussion for the past six decades, and the subject of many revisions that have add

埃隆·马斯克 (Elon Musk) 对 SpaceX 和人类未来的计划植根于 20 世纪 60 年代的一个想法，当时天文学家开始在宇宙中寻找神秘、未知的无线电源。苏联天文学家尼古拉·卡尔达舍夫 (Nikolai Kardashev) 是当时寻找外星智慧生命的先驱，其中一些信号令他着迷。他对地球上可能检测到来自潜在外星文明的传播的想法很感兴趣，因此提出了一个对此类文明进行分类的标准。
