Dyson spheres, the hypothetical mega-structures that advanced alien civilizations might use to enclose a star and harness its energy, suffer from a fatal flaw: They are catastrophically unstable. But ...

There are three ways to look for evidence of alien technological civilizations. One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts ...

Recently, according to Live Science, the results of two scientific studies have been released that could, if verified, prove the existence of advanced alien civilizations elsewhere in the universe ...

A cosmologist suggests we should look for exploration, along with energy signatures, to try and find aliens. Dyson spheres of some kind may be built to harvest energy from dark matter in black holes.

What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar ...

For more than half a century, scientists have wondered if searching for technosignatures like Dyson Spheres from super-advanced civilizations could help us discover intelligent life elsewhere in the ...

Researchers found seven stars in our galaxy that might host alien megastructures called Dyson spheres. But these stars' strange behavior could also be explained by other phenomena, like clouds of dust ...

A recent study reveals that certain configurations of artificial spheres and rings around binary stars could be stable. The work of Colin McInnes, published in the Monthly Notices of the Royal ...

Two surveys of millions of stars in our galaxy have revealed mysterious spikes in infrared heat coming from dozens of them. Astronomers say this could be evidence for alien civilisations harnessing ...
