Ancient Civilizations and Tiny Dyson Spheres

Ancient Civilizations and Tiny Dyson Spheres

Perhaps the greatest challenge facing a civilization is surviving its infancy. We ourselves struggle with that as we try to grow past the age of nation states, warfare and the need for weapons that can cause our own extinction. But once past that infancy, for many civilizations, our own included, there lies a future problem […]

Is This Evidence Of An Alien Civilization?

Is This Evidence Of An Alien Civilization?

In 1981 astronomer Robert Kirshner made a shocking intergalactic discovery. 700 million light years from the Earth lies an enormous, barren sphere known as the Bootes Void. Its very existence challenges what we know about the universe and its origins. The Void is at least ten times larger than the rules of modern physics say […]

10 Ways SETI Might Detect Alien Civilizations And What They Might Be Like

10 Ways SETI Might Detect Alien Civilizations And What They Might Be Like

One of the biggest problems facing the Search for Extraterrestrial Intelligence is that we really have little idea of what one would look like. This makes the prospect of detecting them difficult, after all, how do you look for something that you haven’t ever seen before? But there are clues, mainly based on things our […]

Do Alien Civilizations Invariably Destroy Themselves?

Do Alien Civilizations Invariably Destroy Themselves?

All too often, speculating about alien civilizations is tied directly to the only civilization that we have so far observed, our own. We literally work from a sampling of one, and until we actually detect another civilization that won’t change, no matter how anthropocentric and uncertain it might seem. After all, we are human, and […]

Cosmic Archeology: Detecting Dead Civilizations through Necromarkers

While I am generally a positivist when it comes to the human race, I think we can do great things as a species if we simply play our cards right, and I even think its likely that we will, but I would be remiss not to also accept that we may not and could easily […]

What If We Contacted An Alien Civilization?

What If We Contacted An Alien Civilization?

According to our best estimates – there are 100 billion galaxies in our observable universe. One hundred BILLION. Let that sink in for a second. Our sun is just one solar system in one galaxy… of 100 billion…. That we can see. While we may not have found life yet, I for one feel like […]

Is This Why We Haven’t Found Alien Civilizations? | STELLAR

Thank you to Draper and its Hack The Moon initiative for supporting PBS Digital Studios. People have always dreamed of ways to be closer to the stars. That’s what brought us here to Mauna Kea in Hawaii. From this spot, we can stand nearer to the sky, and see farther and clearer than almost anywhere […]

Are We Among the First Civilizations in the Universe?

Are We Among the First Civilizations in the Universe?

When discussing SETI and the Fermi Paradox the focus tends to be on distance, the idea that an alien civilization could exist in relatively close proximity to earth enough that we could detect them. So far we haven’t found anything. But there is another aspect to the potential existence of exocivilizations; that they may be […]

Alien Civilizations and the Permanent State of Reset

Alien Civilizations and the Permanent State of Reset

I often poke fun at Earth for not being a perfect planet, nor orbiting a perfect sun, nor being located in a perfect galaxy, and all of those things are true. There very likely are better worlds in the universe for life than this one. But, perhaps more likely, there are many worlds that are […]
