Synthesized answer
The provided passages do not explicitly list all remaining unanswered questions. However, they do mention several profound topics that are explored within "The Fabric of Reality," which suggests they are areas of ongoing inquiry or contemplation. These include the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe [1, 2].
The book also connects leading-edge research and thinking on topics such as quantum computers, the physics of time travel, and the comprehensibility of nature [2]. While these are discussed, the passages do not specify which, if any, of these questions remain unanswered.

From the book
cal limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here—for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert—is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence.

Title: The Fabric of Reality by David Deutsch Description: A penetrating exploration of the new physics, including time travel, quantum computers, and the multiverse from an award-winning physicist For David Deutsch, a physicist of unusual originality, quantum theory contains our most fundamental knowledge of the physical world. Taken literally, it implies that there are many universes “parallel” to the one we see around us. This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview based on four main strands: • Quantum physics and its…
