There’s about 170 billion galaxies in the observable universe—and as the technology of our telescopes improves, humans will probably discover as many as a trillion galaxies. Galaxies, like our own, can contain 200 billion or more planets and stars. Inevitably, some of those celestial worlds are capable of bringing forth and nurturing intelligent life. In fact, to some top astronomers, the question is not whether aliens exist, but how many millions of different intelligent extraterrestrial species exist.

With so many possible advanced life forms out there, the obvious question is: Why haven’t humans made contact with them yet? This famous conundrum is called the Fermi Paradox.
There are at least a dozen cogent answers to the Fermi Paradox, but only a few delve into the communication of extraterrestrial civilizations—something which must exist in some form for us to even know about them. And none of the answers about communication adequately discuss what happens to alien language in an accelerating intelligence explosion, which is what must happen for them to be advanced enough to make contact with us.
We will never have more than a few seconds to understand or even notice our millions of neighbors.
Modern day humans—and presumably other advanced intelligent species—are generally in a state of exponential technological and evolutionary growth. That growth may not perfectly reflect Moore’s Law (where microprocessor speeds double approximately every 24 months), but it’s probably somewhere in the ballpark.
