A similar approach might also offer an explanation to the original problem: Alien species might conceal themselves from our observations, e.g. in order to {{w|Prime directive|avoid interfering in the development of civilizations}}. This answer to the Fermi Paradox is commonly called {{w|zoo hypothesis}}.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
