The best books about the mind-boggling mysteries of cosmology

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.

This is my favorite book about the discovery of dark energy—the mysterious stuff that is currently speeding up the expansion of the universe.

It all started in 1998 when cosmologists presented their evidence that the expansion of the universe is accelerating. I was completely stunned and puzzled. I already knew that most of the mass in the universe is in the form of mysterious dark matter, but now I had to acknowledge that the cosmos also contains a large amount of equally puzzling dark energy.

Richard Panek’s book helped me to get to grips with this new reality: the people, planets, stars, and galaxies that we know of constitute just a few percent of everything there is. Panek is a skilled writer; I thoroughly enjoyed how his book not only describes the science but also portrays the scientists.

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.

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.
