Chapter Ten: Where The Moon and the Earth Were Joined (Two Riders Were Approaching)
In order to understand Moore’s transformation it is necessary to fully understand precisely what Watchmen was and what it did. And to understand this it is necessary to appreciate one of its major thematic concerns, the prospect of nuclear annihilation. This aspect of the War entered the scene approximately one picosecond after the creation of the universe, when the electroweak force, unable to cohere once the universe cooled below 1015 K, split into the electromagnetic force, which would go on to underpin more or less the entirety of communication, and the weak nuclear force. This latter force was responsible for a phenomenon called beta decay, in which a neutron can transform itself into a proton by expelling an electron, along with other forms of radioactive decay. Together, along with gravity and the strong nuclear force, they create a delicate mathematical balance in which matter and life are possible. And yet within that crucial weak force is a terrifying implication.
This implication (and indeed the weak force itself) went unnoticed for approximately fourteen billion years, until German chemists Otto Hahn and Fritz Strassman first achieved nuclear fission in 1938. Their work, of course, was simply a momentary endpoint of a larger chain of thought—the revolutions of theoretical physics that swept the scientific community in the early 20th century, upending the classical notions of the world and how it worked. Einstein, Bohr, Heisenberg, and the rest, in a series of dizzying discoveries over the course of decades, unseated the idea of a fixed and knowable universe, finding instead a universe that is fundamentally ordered by human perception, where the act of looking shapes the thing being observed—a quantum revolution that brought, in its wake, the possibility of magic. And then, with Hahn and Strassman, a very different possibility.
Hahn and Strassman conducted an experiment in which they bombarded uranium with neutrons. Observing the result, they discovered to their astonishment that the process had created atoms of barium. Reading a letter about these results, their former colleague Lisse Meitner, a Jewish chemist who had fled Germany earlier in the year, she reasoned that if Niels Bohr’s theory of the atomic nucleus, which held that it worked more or less like a drop of liquid, were correct then a very large nucleus like uranium would be unstable—indeed, unstable enough that the weak force impact of a neutron could lead the nucleus to stretch and eventually snap like a cell dividing into two. Running the calculations further, Meitner realized that the result would have less mass than the original atom, and that the lost mass must be converted into energy—indeed, a tremendous amount of energy, at least for a single atomic reaction, although on its own it was barely enough to move a speck of dust.
Word of the discovery spread quickly, and in early 1939 Niels Bohr brought word across the Atlantic as he traveled to lecture at Princeton. This set off a wave of experimentation and theorization, in which several scientists including Leó Szilárd, Enrico Fermi, and Frédéric Joliot-Curie all came to the same realization: the reaction released more than one neutron.…
