Could We Build A Real-Life Death Star

 One of the most infamous weapons in science-fiction movie history is the Death Star, a moon-size planet destroyer from the “Star Wars” universe. Back in 2012, more than 25,000 people signed a petition asking the U.S. government to construct it’s own Death Star, but is it actually possible? Rod Pyle, author of the book “Blueprint for a Battlestar: Serious Scientific Explanations Behind Sci-Fi’s Greatest Inventions,” estimates it would take 830,000 years of Earth’s current steel output to create enough metal for the hull of the superstructure of the Death Star alone. He adds that rocket launches to send all that metal and other building materials to space would pollute the atmosphere so badly that no one could live on Earth. Additionally, the Death Star is at most 100 miles in diameter, and would not be able to survive long in low Earth orbit, and putting it into a higher orbit is possible, but would require a “prohibitive” amount of rocket fuel. Not to mention, according to the White House’s response to the online petition, it would cost $850 quadrillion to build. (Fox
