NASA Study Says We May Be Alone in the Universe Because of the “Great Filter”

Anyone involved with or even just interested in the search for extraterrestrial life inevitably runs up against the wall known as the Fermi paradox. During a casual conversation about UFOs with fellow physicists in the 1950s, Enrico Fermi, the creator of the world’s first nuclear reactor, listened to arguments that the universe should be teeming with life since the Milky Way galaxy alone has billions of stars with the potential to have generated life in the same manner as it happened on Earth, but billions of years ago … giving that life time to become much more advanced and capable of travel around the universe. Fermi immortalized his name one more time by pondering the proposal and then asking the question (paraphrased): “If there is so much life around … where is everybody?” Many scientists have tried to resolve the Fermi paradox. One of the more recent arguments against the Fermi paradox is called Great Filter – a nearly impenetrable wall that is blocking life everywhere from advancing to the space travel level. That theory just got a boost from an unlikely source – NASA. Why would NASA – an organization with the mission to look for life on other planets – suddenly accept a theory that could put it out of business? What would Fermi think?
