For the last 60 years, we’ve had our eyes and ears glued to the cosmos looking and listening for some sign letting us know we’re not all alone in the galaxy. And the more we discover, the harder it is to believe we’re the only ones.

Think about this for a moment; there’s around 2 trillion [2,000,000,000,000 galaxies] galaxies in the observable universe. Each one of those galaxies have on average 100 million stars. Some supergiants have one hundred trillion stars, and our Milky Way Galaxy has between 100 to 400 billion stars alone. It is likely that there’s at least this many planets floating around all those stars, and complex planetary systems that may resemble our own Solar System.

It brings us to the big question: where is everyone, and why haven’t we been contacted by an extra-terrestrial civilization from even inside our own galaxy? There should be many advanced civilizations out there, and we should have heard something from someone by now.

There are quite a few possible explanations for the ‘Great Silence’, and some researchers think they may have found some answers to this so-called paradox.

What will happen to humanity in the future? Will we finally make contact with another alien civilization, or are we simply alone in the universe?

Will artificial intelligence end up destroying us and other advanced civilizations, or is there a chilling possibility that AI has already done this?
