SETI Sync Problem|教育線上App不用買-HotApp4Game

The Search for Extraterrestrial Intelligence has been in existence for about 50 years, and has found practically nothing of interest. Given the huge number of about 200 billion stars in our galaxy, why have we not seen any verified evidence of extraterrestrial intelligence? As Enrico Fermi famously asked in the 1940s, "Where is everybody?"In the vast time and space expanse of our galaxy, stars, their planetary systems and any potential for intelligent life come and go like fireflies on a warm summer’s night. SETI synchronicity Problem is an accurate interactive visual simulation of the synchronicity problem that exists when intelligent civilizations try to detect one another. This application will stretch your mind to the incredible reality of our galaxy and will give you a new perspective of the immensity of the cosmos.
