On September 14, 2015, after 50 years of searching, gravitational waves were detected for the first time, and astronomy changed forever. Up until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays, and the rest. But gravitational waves - ripples in the fabric of space and time - are unrelenting, passing through barriers that stop light dead.

At the two four-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015, they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected, and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a powerful new path to understand the workings of the universe.

Brian Clegg was always fascinated by Isaac Asimov’s classic Foundation series of books, in which the future is predicted using sophisticated mathematical modeling of human psychology and behavior. Only much later did he realize that Asimov’s "psychohistory" had a real-world equivalent: game theory. Originating in the study of probabilistic gambling games that depend on a random source—the throw of a dice or the toss of a coin—game theory soon came to be applied to human interactions: essentially, what was the best strategy to win whatever you were doing?

Providing a post-COP26 perspective on the climate emergency, Hothouse Earth: An Inhabitant's Guide acknowledges that it is now practically impossible to keep this side of the 1.5°C dangerous climate change guardrail. The upshot is that we can no longer dodge the arrival of a disastrous, all-pervasive climate breakdown that will come. Bill McGuire explains the science behind the climate crisis, painting a blunt but authentic picture of the sort of world our children will grow old in, and our grandchildren grow up in, a world that we catch only glimpses of today.

Since the 1950s, scientists have attempted to harness nuclear fusion—the process that creates the Sun's energy—to generate near-limitless amounts of electricity. But the fact that we still have no fusion power plants is testament to the complexities of the challenge. Now, the deepening climate crisis means that researchers around the world are in a race to create a mini-Sun here on Earth. The glittering prize is an energy source that emits no greenhouse gases and could solve energy equity and supply issues at a stroke.

In this bundle, astrophysicist Andrew May take a deep dive into space exploration and our continued and evolving fascination with the cosmos. Astrobiology: May gives an expert overview of our current state of knowledge, looking at how life started on Earth, the tell-tale signatures it produces, and how such signatures might be detected elsewhere in the Solar System. Destination Mars: May traces the history of our fascination with the Red Planet. The Space Business: May provides an in-depth look at the triumphs and heroic failures of quixotic quests to commercialize the final frontier.
