Physics and Star Wars
To estimate the effects of the second Death Star, Minton looks into its mass. According to estimated data from some students of Lehigh University, the steel mass needed for building one would be around 770 kilograms times the mass cubed in weight. This would give the Death Star of about ten to the power of nineteen kilograms in mass. Using this data, Minton produces equations that lead him to conclude the fragments would hit the moons surface so hard causing craters almost four times the size of the Chicxulub crater in Mexico. This impact would cause a planetary firestorm and vaporize all lifeforms on the moon.
Timeline of United States discoveries
The RMS "Titanic" was an "Olympic" class passenger liner owned by the White Star Line and was built at the Harland and Wolff shipyard in Belfast, in what is now Northern Ireland. At the time of her construction, she was the largest passenger steamship in the world. Shortly before midnight on April 14, 1912, four days into the ship's maiden voyage, "Titanic" struck an iceberg and sank two hours and forty minutes later, early on April 15, 1912. The sinking resulted in the deaths of 1,517 of the 2,223 people on board, making it one of the deadliest peacetime maritime disasters in history. After nearly 74 years of being lost at sea on the bottom of the ocean floor, a joint Franco-American expedition led by American oceanographer Dr. Robert D. Ballard, discovered the wreckage of the RMS "Titanic" two miles (3 km) beneath the waves of the North Atlantic on September 1, 1985. Ballard was then forced to wait a year for weather conditions favorable to a manned mission to view the wreck at close range. In 1986, Ballard and his two-man crew, in the ALVIN submersible, made the first two and-a-half hour descent to the ocean floor to view the wreck first-hand. Over the next few days, they descended again and again and, using the Jason Jr. remote camera, recorded the first scenes of the ruined interior of the luxury liner.
