Topics
AJ和Hecklefish讨论了卡尔达舍夫等级，这是一种根据文明利用能量的总量来对文明进行分类的方法。他们解释说，人类目前处于0.7级左右，并探讨了不同等级文明的特征，包括1级文明能够利用整个行星的能量，2级文明能够利用整个恒星系统的能量（例如通过戴森球），3级文明能够利用整个星系的能量。他们还讨论了费米悖论，即宇宙中存在大量可能支持生命的天体，但我们却找不到其他文明。他们提出，一个可能的解释是，当文明达到卡尔达舍夫等级的某一阶段时，它们往往会自我毁灭。他们还讨论了其他衡量文明的方法，例如巴罗提出的微观维度掌握尺度，以及人类未来可能面临的挑战和机遇，包括人工智能的发展和与外星文明接触的可能性。 AJ和Hecklefish深入探讨了卡尔达舍夫等级的各个级别，从0级文明到6级文明，并对每个级别的能量利用能力和科技水平进行了详细的描述。他们还分析了不同等级文明可能存在的技术和社会形态，例如戴森球、超光速星际旅行、宇宙操控等。此外，他们还讨论了费米悖论，并提出了几种可能的解释，包括高级文明的自我毁灭和故意隐藏等。最后，他们探讨了人类文明的未来发展方向，以及与外星文明接触可能带来的风险和机遇。

**THE KARDASHEV SCALE. **

We have no idea what an alien civilization would look like. Humans are evolved primates. What if an alien species is reptilian? Or more like an insect? Or a hybrid of these? Or maybe something completely unique that we couldn't even imagine.  

There is only one set of universal laws that every species must follow. Physics. Specifically energy.  

One way to measure a civilization is by its energy consumption. This is done with the Kardashev Scale.  

By using the Kardashev Scale, we can address some big questions about alien civilizations. Like: Fermi's Paradox. It's estimated that there are 40 billion Earth-like planets in the Milky Way that could support life. Certainly a few of these should have given rise to intelligent life. And if so, where is everyone?  

A recent study done by researchers at JPL and CalTech states that when a civilization finally reaches a certain point on the Kardashev Scale, it destroys itself. Which is why we haven't discovered any evidence. They're gone.  

And the Kardashev Scale addresses the most worrisome theory of all. If there are advanced civilizations in our universe, it's probably best if we don't make contact with them.   

Let's find out why.
