Existential Physics

Více o knize

A contrarian scientist explores the profound questions raised by modern physics and its implications for the human condition. The origin of the universe remains an enigma, with doubts about our ability to ever fully explain it. Concepts such as universes within particles or conscious particles are deemed unscientific, as is the idea of our universe being a computer simulation. However, the possibility of a conscious universe is harder to dismiss. Sabine Hossenfelder highlights the connections between quantum entanglement, vacuum energy, and beliefs in alternative healing, as well as the notion that loved ones persist through quantum mechanics. Both science and religion share roots and address fundamental questions about existence, knowledge, and our origins. Physics stands at the forefront of these inquiries, revealing which spiritual ideas align with natural laws. Hossenfelder tackles critical questions in physics: Does the past still exist? Do particles think? Was the universe designed for us? Has physics negated free will? Will a theory of everything ever emerge? She outlines the progress physicists have made, the boundaries of current understanding, and the likelihood of some questions remaining forever unanswered. This engaging book provides a clear perspective on what we know and what remains a mystery.
