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 keel of the third sister, "Baltic" had been laid down at Harland & Wolff in June 1902, while construction on "Cedric" was still underway. One notable instance in her construction was once her keel was fitted in place, White Star gave orders for her length to be extended by 28 feet. This change in plans required builders to cut her keel in two, move the after end backwards and install the new addition in between. Their reasons for this addition was likely to provide more spaces for passenger accommodations, which combined added up to 2,850 passengers Although "Baltic" was designed with the same layout for Third Class passengers as "Cedric", with a capacity of 2,000, her First and Second Class capacities were significantly greater. First Class was increased to a capacity for 425 passengers, while capacity for Second Class was extended to 450 passengers, almost twice that of "Cedric" and three times that of "Celtic". Simultaneously, the added length also increased her gross tonnage to 23,884, making her now the largest ship in the world. "Baltic" was launched on 12 November 1903, subsequently fitted out and delivered to White Star on 23 June 1904, and sailed on her maiden voyage on 29 June.
