The Big Bang theory says that our universe began with a colossal explosion, about 14 billion years ago, and has been expanding and cooling ever since. Astronomers combine mathematical models with observations to develop workable theories of how the universe came to be, including Albert Einstein’s general theory of relativity along with standard theories of fundamental particles. Today, NASA spacecraft such as the Hubble Space Telescope continue measuring the expansion of the universe. We can now “tell an unbroken story, from inflation to the postinflation period, to the Big Bang and beyond,” says David Kaiser, the Germeshausen Professor of the History of Science and professor of physics at MIT, about the postinflation reheating period that set up the conditions for the Big Bang, and “in some sense puts the ‘bang’ in the Big Bang. It’s this bridge period where all hell breaks loose and matter behaves in anything but a simple way. We can trace a continuous set o
