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.
United States lightship LV-117
During the night of May 14, 1934 "Olympic", sister-ship to the lost "Titanic", was homing in on the lightship's radio beacon. Nearly 75 times larger than the 630-ton lightship, the White Star liner was steaming at about in the center of the western terminus of the trans-Atlantic shipping lanes. By 5.00 am on the morning of May 15, "Olympic" was in thick fog that necessitated the reduction of its speed to 16 knots, then .
