Scientists searching for alien Dyson spheres face an unexpected challenge: exotic stellar objects called strange stars could produce nearly identical observational signatures, creating a cosmic shell game between natural phenomena and potential technosignatures.
2025 research reveals why we haven't detected aliens: civilizations may evolve past detectable phases in mere decades, radio-bright galaxies hide signals in noise, and we're searching the wrong spectrum with outdated tools.
New research suggests the Fermi paradox might have a simple answer: civilizations plateau at modest technology levels due to natural limits, making them nearly invisible. The silence isn't a mystery but the logical outcome of cosmic sustainability.
Scientists are using AI, machine learning, and advanced telescopes to search for alien technosignatures across radio, optical, and infrared wavelengths. New techniques include hunting for megastructures around distant stars and analyzing millions of signals for patterns that indicate technological civilizations.
