Fans pick 100 books like In Search of the Big Bang

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 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.

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.

There are many introductory books about cosmology out there, but this is the book I read when I was a teenager in high school, and it’s the one I still recommend to everyone (including my wife and my parents).

As its name suggests, this book describes the history and physics of the Big Bang theory, which is just an excuse to discuss cosmology in general. Some of the details are out of date or not quite right, but it’s still a great place to start.

As I recall, this short summary ranges a bit more widely than the two volumes I've listed above. It is short, accessible and to the point, with rather more emphasis on the theory than the observations. I like the fact that it looks forward to possible new discoveries about our Universe and provides a glimpse of topics that lie outside the mainstream of contemporary cosmology. Quantum cosmology, anyone?

If one sets out to understand the universe, one thing one needs to do is understand the laws and rules that govern the matter and energy that makes up the cosmos. The second thing one needs to understand is how it came into existence. In this book, Dan Hooper describes what we know about the first few minutes. Hooper is a theoretical cosmologist at Fermilab, America’s flagship particle physics laboratory. He’s also an excellent author, with a great narrative style. If you want to understand how the Big Bang banged, this is the book for you.

The numbers in physics have always fascinated me. Many think of physics as full of impenetrable equations. Some, like E=mc squared and F=ma, are associated with famous names, Einstein and Newton. But on their own, equations don’t tell us what’s happening. Numbers breathe life into equations, giving meaning to the symbols. In Rees’s beautiful book, he identifies six numbers that have led to the universe around us and to the extraordinary complexity of the world we live in. 

And they are just numbers, like 3 or 0.007. Only six numbers? So few seem astonishing. Modern physics and cosmology do identify others. But in all cases, the conclusion is that you can’t change them, not even a little, and still end up with a universe and world like ours. 

In the book Reality is Not What It Seems, Carlo Rovelli exhorts us to “Stop dreaming of new fields and strange particles; supplementary dimensions, other symmetries, parallel universes, strings, and whatever else.” Oh, but I wanted to dream, and Michio Kaku always takes me on such a fun ride! I loved Kaku’s The Future of the Mind, which inspired me as I wrote my own science fiction novel. So I turned to him again when I wanted to learn more about string theory, the competing theory to Rovelli’s loop quantum gravity and Kaku’s own area of expertise. It was well worth it. At least now I can plumb the allure of that symmetry, the wonder of those parallel worlds, and the fullness of those eleven dimensions—even if I may never see them proven out in my lifetime.

For those wanting to delve deeper into cosmology, I can strongly recommend this clearly written college-level textbook. It develops the equations that govern the expansion of the Universe and shows how they depend on the kinds of matter and radiation that fill the Universe. It explains the origin of structures like galaxies and clusters of galaxies and how that structure evolved over time. And it examines the observations, including of the CMB, that have transformed cosmology into a precision science. 

I’ve used it often in classes; I love it, and the students do too.
