Meeting Hawking
Thomas Hertog explains how he became Stephen Hawking's collaborator.
He achieved top scores, leading to an invitation to Hawking's office, filled with journalists.
insights INSIGHT
Quantum Cosmology Origins
Hawking's work with Jim Hartle on the wave function of the universe stemmed from his PhD work.
The work showed the Big Bang as a singularity where Einstein's theory breaks down.

Wave Function of the Universe
The wave function of the universe describes a superposition of many possible universes.
It's an abstract concept going beyond a single particle's wave function.

In 'A Brief History of Time', Stephen Hawking delves into fundamental questions about the universe, including its origin, the nature of space and time, and the fate of the cosmos. The book discusses key concepts such as the Big Bang, black holes, and the theories of general relativity and quantum mechanics. Hawking also explores the possibility of time travel and wormholes, and he reflects on the intersection of science and philosophy, including the search for a unifying theory of everything and the implications for our understanding of existence and the universe[2][3][4].
On the Origin of Time
Thomas Hertog
In 'On the Origin of Time', Thomas Hertog presents a comprehensive exploration of Stephen Hawking's final theory, which challenges traditional notions of time and space. The book delves into quantum cosmology, string theory, and the concept of the multiverse, offering insights into the origins of the universe and the evolution of physical laws. It is an homage to Hawking's groundbreaking ideas developed over two decades of collaboration.
Is there a multiverse, and if so, how should we think of ourselves within it? In many modern cosmological models, the universe includes more than one realm, with possibly different laws of physics, and these realms may or may not include intelligent observers. There is a longstanding puzzle about how, in such a scenario, we should calculate what we, as presumably intelligent observers ourselves, should expect to see. Today's guest, Thomas Hertog, is a physicist and longstanding collaborator of Stephen Hawking. They worked together (often with James Hartle) to address these questions, and the work is still ongoing.
Thomas Hertog received his Ph.D. in physics from the University of Cambridge. He is currently a professor of theoretical physics at KU Leuven. His new book is On the Origin of Time: Stephen Hawking's Final Theory.
