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 ...

FOUR mysterious stars might be alien mega-structures built to harvest energy output, researchers have hinted. The hypothetical structures dubbed Dyson spheres are being examined for evidence of alien ...

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 ...

If there are alien civilizations in the Universe, some of them could be super advanced. So advanced that they can rip apart planets and create vast shells surrounding a star to capture all its energy.

A Dyson Sphere is the ultimate sci-fi megastructure — an enormous shell or swarm that could harness the entire energy output of a star. But could we ever actually build one? This video dives into the ...
