The alien pandemic may self-destruct before we locate them.

If there are advanced extraterrestrial civilizations constructing massive satellite arrays to harness stellar energy, we ought to detect them. Recent calculations suggest that these structures, known as Dyson spheres, may be more prone to self-destruction before we ever find them.

The concept of a structure capable of capturing the majority of a star’s energy was initially introduced in the 1960s by physicist Freeman Dyson. Astronomers postulate that if such structures exist, we should observe distinct signatures…
