Here’s why it’s so weird that we haven’t found aliens yet

In our vast universe there are nearly 100 billion galaxies, each galaxy contains about 100 to

1,000 billion stars — and founded on what we've learned about planets, there are possibly trillions and trillions of habitable planets ones out there. So, to examine the question in the words of Nobel-prize holding physicist Enrico Fermi: "Where is everybody?" Why haven't we come across any indication for extraterrestrial life? With so many possible places for it to ascend, it might seem extremely odd that we haven't found it — or the fact that it hasn't found us. This confusing question, named the Fermi Paradox after our above-mentioned physicist, isn't just bizarre — it's frightening. Just think about it. Even if life is extremely exceptional, it should have arisen somewhere in our own galaxy alone in the previous 11 billion years. As the video below clarifies, if only 0.1% of possibly habitable planets in our galaxy sheltered life, there should still be a million planets comprising life. For an exceptional description of the Fermi Paradox, watch this fantastic YouTube video by Kurz Gesagt, which I first spotted on io9:
