The Great Disrupter

The elevation of Donald Trump to the American presidency has spelt a dismal descent in political leadership, and more than suggests a systemic decay in the American way of life. Selfsame corruption haunts other societies. But Trump's ascendency cast a stark spotlight on the nation that was the erstwhile leader of the free world.

Cosmic Obesity

According to a conjecture called cosmic inflation, just after the Big Bang, before many of the fundamental physics forces had even taken hold, the size of the universe mushroomed from next to nothing to the size of a dime; at an expansion rate faster than the speed of light.

Bird's Eye View

The United States space agency NASA has taken a peek at the Earth below, and found: "the stretching of resources due to the strain placed on the ecological carrying capacity" as well as "the economic stratification of society into elites and masses (or 'commoners')." In that regard, "accumulated surplus is not evenly distributed throughout society, but rather has been controlled by an elite. The mass of the population, while producing the wealth, is only allocated a small portion of it by elites, usually at or just above subsistence levels."

Bonds Beyond

The vast expanse of interstellar space is supposed to be too cold for most chemical reactions to occur. The more frigid it gets, the harder it is to spark a chemical reaction, for lack of energy – the very definition of cold. Yet a vast variety of complex organic molecules are formed in space. Some reactions transpire on the surface of cosmic dust grains, or with a little help from gamma rays or stray high-energy electrons. But most happen beyond the laws of chemistry.
