The planetarium hypothesis, conceived in 2001 by Stephen Baxter, attempts to provide a solution to the Fermi paradox by holding that our astronomical observations represent an illusion, created by a Type III civilization capable of manipulating matter and energy on galactic scales. He postulates that we do not see evidence of extraterrestrial life because the universe has been engineered so that it appears empty of other life.[1]


The hypothesis has been considered by some authors as speculative[2][3] and even next to useless in any practical scientific sense and more related to the theological mode of thinking along with the zoo hypothesis.[4]
