NEW YORK TIMES BESTSELLER • Stephen Hawking’s closest collaborator gives the mental celebrity’s ultimate ideas on the cosmos—a dramatic revision of the speculation he put ahead in A Transient Historical past of Time.
“This beautifully written ebook gives perception into a rare particular person, the inventive course of, and the scope and limits of our present understanding of the cosmos.”—Lord Martin Rees
Maybe the most important query Stephen Hawking tried to reply in his extraordinary life was how the universe may have created circumstances so completely hospitable to life. In an effort to remedy this thriller, Hawking studied the large bang origin of the universe, however his early work ran right into a disaster when the maths predicted many large bangs producing a multiverse—numerous totally different universes, most of which might be far too weird to harbor life.
Holed up within the theoretical physics division at Cambridge, Stephen Hawking and his good friend and collaborator Thomas Hertog labored on this drawback for twenty years, creating a brand new idea of the cosmos that might account for the emergence of life. Peering into the acute quantum physics of cosmic holograms and venturing far again in time to our deepest roots, they had been startled to discover a deeper degree of evolution through which the bodily legal guidelines themselves rework and simplify till particles, forces, and even time itself fades away. This discovery led them to a revolutionary concept: The legal guidelines of physics are usually not set in stone however are born and co-evolve because the universe they govern takes form. As Hawking’s ultimate days drew close to, the 2 collaborators printed their idea, which proposed a radical new Darwinian perspective on the origins of our universe.
On the Origin of Time gives a putting new imaginative and prescient of the universe’s start that can profoundly rework the way in which we take into consideration our place within the order of the cosmos and will finally show to be Hawking’s biggest legacy.

A Rare Breed of Authentic Science Books
After reading Hawkingâs *A Brief History of Time*, and Kipp Thorneâs *Black Holes and Time Warps*, I had the impression that Hawking is not only a great scientist but also a deep philosopher of science. He is a rare breed of scientist who combines solid technical skills with profound insights. He is able to see both the forest and the trees. All this with little âegoâ to be seen in his writings or in his followers. Hertogâs book confirms these conclusions.
Hertog is a student-cum-fellow of Stephen Hawking. He is an outstanding physicist that knows what he is writing about. The book analyzes how scientific debate is motivated by philosophical positions. In particular, the book explains the journey that Hawking traveled from the position of Einstein to that of Lemaître. I will not summarize these positions so as not to spoil your appetite to read the book! It is an interesting journey that is worth the struggle.
The book elegantly weaves scientific theories with the history of science. The style and prose are simple and clear.
The discussion of time is subsumed into the discussion of quantum holography. The author emphasizes that spacetime and gravity are âemergent phenomena.â âHolography ingrains a fundamental element of emergence into the very roots of physicsâinto the fabric of spacetime itself.â According to the author, âHolographic cosmology excises the multiverse like Ockhamâs razor.â An important insight is that âthere is an upper bound on the amount of information that black holes can store.â In contrast, âmultiverse cosmology assumes that our cosmological theories can contain an arbitrarily large amount of information without affecting the cosmos they describe. But holographic cosmology paints a very different picture.â
The last chapter is mostly philosophical. The main message is that we ought to be âAt Home in the Universe.â This is quite enlightening. But the discussion overall is not as stimulating as the rest of the book. The author probably needs to take another look at that chapter.
Overall, despite the many books on black holes, relativity, and quantum physics, this book presents a unique perspective. It also shows the profound value of Hawkingâs contributions to modern science and philosophy.

A good argument against simplistic reductionism
To my surprise, this book is not a glorification of the multiverse concept â Marvel has that turf well-covered these days, yes? â but a thoughtful and considered navigation of the terrifyingly dark and murky waters between Aristotelian absolutism and profligate quantum possibilities. There is, for example, this striking line from the final chapter: “The multiverse evaporates like snow before the sun in quantum cosmology.” I had no idea that the thoughts of Hawking and his associates on the multiverse were this nuanced towards the end of his life.
I was fascinated to discover that Hawking vacillated from a bottom-up universe early in his life to a top-down universe later. It would have been fascinating to discuss with him the non-binary alternative that he seems never to have considered: the Matryoshka universe, in which different levels of certainty, complexity, and existence exist simultaneously and nested within each other, with the most robust forming the exterior, and the most significant complexity on the interior. And even without stating that, and despite Hertog declaring a top-down only strategy, he and Hawking and their associates nonetheless seem to have considered, perhaps without recognizing it, a decidedly Russian-doll-like concept in quotes like this one: “⦠there isn’t the slightest ontological difference between the fact that Christian religions dominated Western Europe ⦠and the value of the anomalous magnetic moment of the electron in the standard model of particle physics. They are both frozen accidents, just at widely different levels of complexity.”
It makes sense that the least time-like and most encompassing of Hawking’s “frozen accidents” also form the most stable and encompassing of the layers, and perhaps this is why Hawking refers to this as a top-down universe. Just as a frozen alphabet enables communication and the formation of new levels of linguistic complexity, Hawking’s earliest frozen accidents become the Standard Model of particle physics, allowing us to see and understand the most distant reaches of the visible universe. Also, a fully emergent universe enables the interplay of particles, space, and time, allowing levels of space to proceed those that we know from a classical perspective, just as some simpler particles, such as quarks, join together into more complex particles such as protons and neutrons.
Perhaps a top-down universe versus a Matryoshka universe is more a matter of linguistic connotation and preference. Top-down better conveys the concept of a tree with the diversification of complexity in the higher branches than the more linear implication of nested dolls. On the other hand, top-down has an unfortunate connotation of premeditated design that is not what Hawking intended, yet it comes to mind quickly for anyone reading the phrase.
However one describes Hawking’s final and more nuanced concept time, this book is a worthy and thought-provoking read.

I worked my way through this excellent book quite carefully, absorbing as much of the physics as my limited mathematical skills allowed. Nevertheless, I still was able to grasp the concepts (I think) that are presented so well for the layman. The final pages of the book delve more into the philosophy of Hawkingâs theory, and I found that part equally fascinating and enlightening.
A great book, if you can stick with it and work your way through.

Ich lese gerne und viel. Dies ist eines der wichtigsten Bücher, das ich je gelesen habe. Fazinierend unter so vielen Aspekten. Ich kenne kein anderes Buch, das en passant so gut erklärt wie theoretische Physik “funktioniert”. Allein diese Eigenschaft, sollte das Buch zur Pflichtlektüre für alle “Wissenschaftsskeptiker” machen. Wie anschaulich der Autor die komplexen Zusammenhänge der jüngeren Physik (Quantenphysik, Relativität, Kosmologie) aufdröselt ist ganz groÃes Kino. Zudem gibt es wunderbare Einblicke in das angelsächsische Uni-System (ich hatte das Glück bei einem Briten zu studieren und habe manches wiedererkannt). Dann zeigt es insbesondere uns Deutschen (die Menschen mit Behinderung gerne in Werkstattbetriebe abschieben, währen man die z. B in NL deutlich häufiger als Kolleg*innen trifft), was diese Menschen groÃartiges leisten können, wenn man sie lässt. OK, Stephen Hawking war sicher ein Ausnahmetalent, aber trotzdem ist das ein deutlicher Fingerzeig. Am Ende gelingt es dem Auto, den Bogen zwischen Physik und Philosophie zu verbinden. Zwei Fachrichtungen, die sich mit unterschiedlichen Methoden ähnliche Fragen widmen. Kaufen, lesen, weitergeben!
