Just over 95% of our Universe comes in the shrouded form of dark energy and dark matter that we can neither explain nor directly detect. Together, these two dark entities play out a cosmic battle of epic proportions, with the gravity of dark matter slowly pulling structures in the Universe together, and dark energy fuelling the Universe's accelerated expansion, making it ever harder for those structures to grow. In this book we will explore this dark enigma and introduce the cosmologist's toolkit of observations and techniques that allow us to confront different theories on the dark Universe. I'll explain why I believe that, to truly understand the dark Universe, we will need some new physics that will forever change our cosmic view.

Final-year undergraduates, new PhD students and early-career scientists.

Catherine Heymans is professor of observational cosmology at the Institute for Astronomy in the University of Edinburgh, UK, and a European Research Council fellow. She specialises in observing the dark side of our Universe and co-leads the European Southern Observatory KiDS analysis team, using deep sky observations to test whether we need to go beyond Einstein with our current theory of gravity. Catherine has co-authored over 100 technical articles in peer-reviewed journals and a number of articles for Physics World magazine. She is devoted to promoting the public's understanding of her research, both virtually through a Massive Open Online Course 'AstroTech', which has attracted over 30 000 students worldwide, and in person through a wide range of events including art and science festivals. In recognition of this work, she was awarded the 2017 Darwin Lectureship from the Royal Astronomical Society. When Catherine is not busy unveiling the mysteries of the Universe or enthusiastically lecturing undergraduates, she can usually be found building sandcastles and paddling in the sea with her three small children.
