In the past, I have read lots of science fiction, but few books challenged my imagination as much as this wonderful book about parallel universes. The reason? It’s not fiction, it’s science!

Yes, I knew that some physicists had been playing with the idea of extra dimensions and parallel worlds. But it took the profound knowledge of a professional physicist and the eloquent writing style of an experienced communicator like Brian Greene to make me truly understand the weird concept of the Multiverse and the many different ways in which it might manifest itself.

Probably there’s a parallel world in which I find the whole topic too tough or too abstract, but in this one, I simply couldn’t put this book away.

This 1986 book (revised in 1999) helped me to understand the Big Bang theory. I read it during a holiday in Italy when I was just starting my career as an astronomy writer. What I had read about the Big Bang so far was either extremely elementary (not really explaining anything at all) or full of jargon and dense with equations.

But John Gribbin knew exactly how to strike the perfect balance between the two. While my wife and one-year-old son were enjoying the swimming pool, I delved into quantum physics, expanding space, and the cosmic background radiation, all presented at a level an interested high-school student could understand.

Obviously, some parts of this book are obsolete by now, but it’s still one of my all-time favorites.

I love it when I first read about new mind-boggling concepts in cosmology. That’s what happened with this elegant book about gravitational waves—minute undulations of spacetime produced by colliding black holes.

Einstein theorized about them long before I was born, but it wasn’t until the 1970s that scientists first started to really hunt for them. I never paid much interest until Marcia Bartusiak described the quest in much detail in her very accessible book back in 2000. Since then, I have become hooked on the subject.

It’s great to see that Bartusiak published an updated edition in 2017, shortly after gravitational waves were first detected. 

This book may well be the next best thing to spending an afternoon with Stephen Hawking.

After all, Belgian theoretical physicist Thomas Hertog has been one of Hawking’s closest collaborators in the years before the wheelchair-bound genius died in 2018. I liked how Hertog alternates difficult theoretical concepts with his personal accounts and experiences of working with an iconic figure like Hawking.

I especially love this book because it is about one of the greatest unsolved mysteries of science: the true nature of time. In what Hertog calls "Hawking’s final theory," the laws of nature do not precede the Big Bang but co-evolve with the early universe itself.

I have to admit that parts of the book were really hard for me to understand, but I was flabbergasted by the suggestion that our observations may have a tangible influence on the evolution and the properties of the universe itself.

This Harvard-trained cosmologist takes us on a journey into the universe, from colliding black holes to neutrons and protons “faking it” as elementary particles. If you ever wondered why the universe has more matter than antimatter, and what is dark matter made of, this book is for you. And physics is about more than theories; it’s about people doing physics. Black lives matter, and Black lives are the stuff of stars. Chanda Prescod-Weinstein shares her exploration of a universe that is “bigger than the bad things that are happening to us.” Along the way, we gain new clues to the fate of our galaxies full of stars.

I savored this book sip by sip, wishing that each chapter would have lasted a little longer, a little longer. I felt a “healthy envy” for anyone lucky enough to have had a teacher like Klein in high school.

It’s impossible not to fall in love with the cosmos while reading his work. His ability to explain complex scientific concepts in an accessible and poetic manner is admirable.

Each chapter has given me an unforgettable early morning coffee, revealing at a pace the magic that science holds in every corner.

Every good book recommendation list needs a twist. The nature of this list tends to lend itself to more fantasy/ fiction books, but this one is different. This book was like standing under a night sky, staring up at the stars, and feeling simultaneously insignificant and extraordinary.

I love how it made the universe feel vast and beautiful yet somehow personal. It’s not just science—it’s poetry, a reminder of how miraculous our existence is. It’s the twist on my list, but I recommend it because it showed me how the mystery of the cosmos mirrors the wonder of childhood discovery. It’s breathtaking and grounding all at once.

Apart from offering a particular perspective on cosmology and extragalactic astrophysics, the well-known heterodox astrophysicist Halton Arp offers some observations on the corruption of academic science and the difficulties scientists claiming new ideas face.

I do not think what he says about astronomy is right, but certainly his complaints on how physics and astronomy gets done contains valuable wisdom on sociology of science.

This book covers a dizzying array of human thought: Greene’s trademark is physics, of course – but in this wildly ambitious work, the Columbia University physicist also dives into evolution, the origins of human culture, the origins of art and music and religion – even the puzzle of consciousness and the paradox of free will. He tackles the deepest of questions – including the problem of finding “meaning” in a universe governed only by the laws of physics. Be prepared to go slow. Your brain will get a workout – but it will be worth every minute of your time.

I love Stephan Hawking’s A Brief History of Time because it was the first book that inspired me to become a cosmologist. It is a terrific overview of the science behind the modern belief in the Big Bang and what has followed.

It is told with Hawking’s wry sense of humor and unique ability to make complex concepts understandable to the layperson and budding scientist, which I was at the time. It is a fantastic start for my readers of all persuasions.
