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.
White Star Line
The losses of the "Titanic" and "Britannic" left "Olympic" as the only surviving member of White Star's planned trio of express liners. In 1922 the White Star Line obtained two former German liners which had been ceded to Britain as war reparations under the terms of the Treaty of Versailles, ostensibly as replacements for the war losses of "Britannic", "Oceanic", "Arabic", "Cymric" and "Laurentic".: The former "SS Bismarck" which was renamed "Majestic", and the former "SS Columbus" which was renamed "Homeric". At 56,551 gross tons, "Majestic" was then the world's largest liner and became the company's flagship. The two former German liners operated successfully alongside "Olympic" for an express service on the Southampton–New York route until the Great Depression reduced demand after 1930.
