No near neighbors: Closest technologically advanced aliens may be 33,000 light-years from Earth
A recent study indicates that technologically advanced alien civilizations could be extremely rare, potentially located as far as 33,000 light-years from Earth. This research highlights the importance of specific planetary conditions, such as the presence of plate tectonics and the right balance of gases like carbon dioxide and oxygen, in fostering life. Understanding the rarity of such conditions can reshape our perspective on the search for extraterrestrial life and the vastness of the universe.
