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.
RMS Leinster
The exact number of dead is unknown but researchers from the National Maritime Museum believe it was at least 564, this would make it the largest single loss of life in the Irish Sea.
In 1895, the City of Dublin Steam Packet Company ordered four steamers for Royal Mail service, named for four provinces of Ireland: RMS "Leinster", RMS , RMS "Munster", and RMS "Ulster". The "Leinster" was a 3,069-ton packet steamship with a service speed of . The vessel, which was built at Laird's in Birkenhead, England, was driven by two independent four-cylinder triple-expansion steam engines. During the First World War, the twin-propellered ship was armed with one 12 pounder and two signal guns.
