Area 51 is a secret military base in Nevada. It has been mentioned in news and culture for decades because it is rumored that the base stores crashed alien aircraft and is working on projects such as time travel, weather control, teleportation and exotic weapons. It is so secret, it is rumored that even the U.S. president does not know what goes on there. Some of the activities sound far-fetched, but they must be doing something extraordinary considering the fact they are so secretive. Any thoughts?
