Supernova
Violent explosion of a star. The star is destroyed, with a remnant forming a neutron star (pulsar) or black hole (collapsar) depending on the residual mass. There are generally two forms of supernova. One results at the end of the life of a star with at least about eight solar masses, which in a series of progressively shorter-lived and less efficient thermonuclear reactions generates ever heavier chemical elements in layers about the core. Effectively this is a star that lives fast and dies young. When each step in the process chokes up the core with nuclear "ash", contractions follow under gravity, driving up temperatures until they are sufficient to synthesise the next heavy element from this waste product. When the core fills with iron, the end point is reached; it takes more energy to fuse iron into anything heavier than the fusion reaction produces. At this point the star collapses, driving temperatures into perhaps twelve figures Kelvin and triggering an explosion that blows most of the star to smithereens. A second type occurs in close orbiting binary systems where one star A, being more massive, evolves more quickly to the red giant phase and develops a thin outer envelope and a core rich in carbon. Its companion B skims off the outer layer, grows in mass and itself evolves to the red giant stage. At this point the carbon-rich star A begins reclaiming the hydrogen; when the gas accreting onto it drives its mass over 1.4 solar masses a huge nuclear reaction ensues and A blows itself apart. Supernova explosions can briefly outshine the combined output of all the stars in at least a modest galaxy. They are also responsible for seeding the Universe with the heavy chemical elements of which the Earth and our very bodies are made.

War. War Never Changes. War, war never changes. In the year 1945, my great-great grandfather, serving in the army, wondered when he get to go home to his wife and the son he never see. He got his wish, when the U.S. ended WWII by dropping an atomic cloud on Hiroshima and Nagasaki. The world awaited Armageddon, instead, something miraculous happened. We began to use atomic energy as a nearly limitless source of power. People enjoyed luxury once thought in the realm of science fiction. Domestic robots, fusion powered cars, portable computers. Then, in the 21st century, people awoke from the American dream. Years of consumption led to the shortages of every major resource. The entire world unraveled. Peace became a distant memory. It is now the year 2077, and we stand on the brink of total war, and I am afraid, for myself, for my wife, for my infant son, because if my time in the army taught me one thing; is that war, war never changes.
Excellent satire - didn't see comments to that end, so find it hard to fathom if most readers, in turn, didn't laugh out loud, and say so. But apparently not.
I am gonna buy it and give it to my nine year old brother
