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.
Death Angel
Death Angel was formed in the San Francisco Bay Area, California, in 1982 by cousins Rob Cavestany (lead guitar, backing vocals), Dennis Pepa (lead vocals, bass), Gus Pepa (rhythm guitar), and Andy Galeon (drums) -- all of Filipino descent. After considering a number of different names for the band, including Dark Fury, Cavestany and D. Pepa settled on the name Death Angel after coming across a book by that title in a book store. In 1983, the band released their first demo, "Heavy Metal Insanity", with Matt Wallace serving as producer. According to Mark Osegueda, the group was then "more like a metal band, more like Iron Maiden, Tygers Of Pan Tang and stuff like that," as the so-called Bay Area thrash movement was only just beginning to rise to prominence at the time and make its influence felt. Osegueda, a second cousin of the other four members who had been working as their roadie, became the group's lead vocalist in 1984 and performed his first show with the band on a bill with Megadeth in April of that year (at one of the four Megadeth gigs to feature Kerry King on guitars).
